Node.JS NPM not working on Windows - windows

I just installed the latest version of nodejs, and while I can get it to run js files just fine, I can't get npm to do anything.
If I open the node.exe, it brings up a prompt, then I separately tried each of the following and none of them work:
> node npm install socket.io
> npm install socket.io
> help
> node help
ALL of the above result in nothing but the line "..." to be returned, then every thing I type in after that, I just get another line of "...".
This is extremely frustrating. What am I doing wrong?

If you had command prompt open whilst installing the latest nodejs then the path to npm in windows path will not be recognised until you close the command prompt and open a new one.
I know this already has an accepted answer but I just found this and then realised my own mistake and thought it might help someone else.

Opening node.exe will bring up the Read–eval–print loop (REPL). Try just:
c:\users\windowslogin>npm install socket.io

ng is not recognized as an internal or external command

Running windows 7 Professional 32bit.
I tried running npm install -g angular-cli both under normal or admin.
I also tried adding it to the Enviorment Variables under PATH: (C:\Users\Administrator\AppData\Roaming\npm\node_modules\angular-cli\bin\ng) , with no success also.
What am i doing wrong?
I solved this problem in accordance with the figure:
run in cmd
npm install -g #angular/cli
and then
( open in Windows 10) Control Panel\All Control Panel Items\System
or accordance with the figure
step 1:
step 2 :
step3:
step4:
step5: add missing ng path
Here is new environment variable that you need add: C:\Users\PK\AppData\Roaming\npm\node_modules\#angular\cli\bin
Finally, restart all opened command prompts and try again.
For me it works with:
npm run ng <command>
Adding C:\Users\DELL\AppData\Roaming\npm to System Variable Path worked for me. Please find your appropriate file path to 'npm'
Also, check if you have added your angular-cli\bin path to the path variable.
I am using WIN 10, just figure it out for this problem.
Type the code below in cmd:
npm config get prefix
and copy&paste the path that you get it from the top into your computer environment variables-->user variables box --> path --> edit -- C:\Program Files\nodejs\node_global, your path may different.
Click Ok and reopen your cmd window, type in ng version, then it works! Cheers!
Just open your command prompt (run as administrator). Ensure node --v is 6.9.0 or higher and npm --v is 3.0.0 r higher.
After that run the following command:
npm install -g #angular/cli
Once angular is installed. you can see an entry of angular cli in the path
C:\Users\Dell\AppData\Roaming\npm\node_modules\#angular
Then try ng help. It will work.
1) Enter below command on command prompt
npm install -g #angular/cli
2) Make sure that C:\Users\_username_\AppData\Roaming\npm this path is not hidden.
3) Add C:\Users\_username_\AppData\Roaming\npm and
C:\Users\_username_\AppData\Roaming\npm \node_modules#angular\cli\bin to both enviroment variable path.
4) Open new command prompt and type ng help. It will work.
With a command
npm install -g #angular/cli#latest
It works fine, I am able to run ng command now.
I solved it few days ago, after having the same problem with other global modules, by adding to:
Environment Tables -> System variables -> Path:
C:\Users\Administrator\AppData\Roaming\npm\node_modules\angular-cli\bin;C:\Program Files\MongoDB\Server\3.2\bin
Note that it must not have any spaces after ;
That turned out to be my problem.
I followed below steps for resolution for this issue in Windows 10:
First make sure you have installed Angular CLI . You can use below
to install same.
npm install -g #angular/cli#latest
Make sure that AppData is visible and navigate to path below.
C:\Users\rkota\AppData\Roaming\npm
Same path can be found by running below too:
npm config get prefix
Add the above path i.e. " C:\Users\rkota\AppData\Roaming\npm" in Environment variable PATH and make sure it got added by running path in command prompt.
Close command prompt and now try to run below:
ng --version
you will be able to see CLI version.
execute following lines in order to solve the issue for both not found and undefined version of ng
npm uninstall -g angular-cli
npm uninstall --save-dev angular-cli
npm cache clean
npm install -g #angular/cli#latest
Instead of using the in-built command prompt better start using the NodeJS installed version of command prompt. Then it is going to work perfectly without any issues.
General problem is that OS tries to find the PATH variable with ng keyword and cannot find it.
For me, even after the steps #behrouzmoslem suggested in the top answers to this post I didn't manage to get it work, because after the launch of ng command OS started to respond, but opens up editor file by the path C:\Users\{username}\AppData\Roaming\npm\node_modules\#angular\cli\bin\ng which is actually funny. So, solution is:
Just use npx before any angular executables.
Eg : npx ng serve for serving the angular app or npx ng build --watch to build with watcher.
If you get the error even after following the above step. then try below.
Since it is a node script. I am using the below option to create as of now.
node C:\Users\Administrator\AppData\Roaming\npm\node_modules\angular-cli\bin\ng version
May be symbolic links are required. Not researched further.
On Further Research:
Set Path as : %PATH%;C:\Users\Administrator\AppData\Roaming\npm;
In Windows, npm.cmd file is in the above path. If the above Environment variable is set, you can execute as
ng version
ng init
Open cmd and type npm install -g #angular/cli
In environment variables, add either in the user variable or System variable "Path" value=C:\Users\your-user\.npm-packages\node_modules\.bin
In cmd: c:\>cd your-new-project-path
...\project-path\> ng new my-app
or ng all-ng-commands
I resolved by adding - %AppData%\npm\node_modules#angular\cli\bin\ path to my environment variables path
close cmd and open it again with admin right or reboot ur system.
for me it works only with the flag --force:
npm install -g #angular/cli --force
If everything is fine then you shoud see the folder node_modules in this path:
C:\Users\YOUR_USERNAME\AppData\Roaming\npm\
I faced same issue when i tried to install angular cli locally with command
npm install #angular/cli#latest
After that i got same issue
C:\Users\vi1kumar\Desktop\tus\ANGULAR\AngularForms>ng -v
'ng' is not recognized as an internal or external command,
operable program or batch file
Than i tried to install it globally
npm install -g #angular/cli#latest
In this case it worked I was wondering that is it not possible to install cli globally ?
After doing some research I found this article very helpful hope it will help someone facing similar issue
Working with multiple versions of Angular CLI
This one almost worked for me, but I had to use: %USERPROFILE%\AppData\Roaming\npm
. In Environment Variables.../System variables/Path
Then when I did CMD: "ng -v" I got the correct response for angular cli.
npm install -g #angular/cli helped for me instead of npm install #angular/cli
1- Install
$ npm install -g #angular/cli
2- Make sure where your ng.cmd is present.
3- Then add this path into variables.
I had the same problem on Windows 7, 64 bits running with npm v3.10.8.
I added the path as it was suggested: ( C:\Users.....(your user name)\AppData\Roaming\npm\node_modules\angular-cli\bin\ng) and uninstalled angular-cli.
After this, I cleared the npm cache by npm cache clean as prompted here https://blogs.msdn.microsoft.com/matt-harrington/2012/02/23/how-to-fix-node-js-npm-permission-problems/. This guarantees there are no leftovers.
Reinstalled angular-cli with npm install -g angular-cliand voila.
Hope that may be useful!
In my case I did below steps.
All Programs -> Node JS-> Right click on Node.js Command Prompt and select properties and from Target string at end copy below
/k "C:\Program Files\nodejs\nodevars.bat"
I launched Visual Studio Code and opened below file
C:\Users\gochinta\AppData\Roaming\Code\User\settings.json and gave below
// Place your settings in this file to overwrite the default settings
{
"terminal.integrated.shellArgs.windows":
["/k", "C:\\Program Files\\nodejs\\nodevars.bat"]
}
Now I typed ng -v in my Visual Studio Code Terminal window and it worked.
I was having the same issue when tried with the syntax "ng new " and solved that simply by updating the existing node version from 5.x.x to 8.x.x. After successful updation of node, the syntax worked perfectly for me. Please update the existing version of node. As it is clearly mentioned in angular documentation that these commands require the node version >= 6.9.x. For reference please check https://angular.io/guide/quickstart. It clearly states "Verify that you are running at least node 6.9.x and npm 3.x.x by running node -v and npm -v in a terminal/console window. Older versions produce errors, but newer versions are fine".
I faced same issue on x86, windows 7;
uninstalled #angular/cli
re-installed #angular/cli
checked & verified environmental variables (no problems there)...
Still same issue:
Solution was the .npmrc file at C:\Users{USERNAME}... change the prefix so that it reads "prefix=${APPDATA}\npm"... Thanks to this website for help in resolving it
For me something was wrong in the PATH enviroment variable. I removed all path related to npm and added at the start of PATH this folder:
c:\Users\<your-user-name>\AppData\Roaming\npm\
Make sure you have ; between paths.
I am facing same issue and it's get resolved. At my end reason is i install node and CLI using other user profile and now i am running ng command from other user login. Since node and cli installed using other user login node is not finding anything on C:\Users\<user name>\AppData\Roaming this path and that's why i am getting this error.
I run npm install -g #angular/cli command and restart my machine. Every thing is working fine.
Sometime in the future. Applicable to Windows 8.1 machine.
Run the following commands
npm install -g #angular/cli
Log out or restart your machine.
This should add the required env path, rather than doing it manually.
I also tried to play with cmd by setting environment variable path & etc, but simple answer is use nodejs command prompt.
So you no need to set environment variable path or anything. When you insalled nodejs it will give it's command prompt, by using that you us "ng" command, without any settings.
Since this question is still asked over and over again one year later I will post my answer here as well.
The clue (on Windows only) is to arrange the entries in the path variable right.
As the NPM wiki tells us:
Because the installer puts C:\Program Files (x86)\nodejs before C:\Users\\AppData\Roaming\npm on your PATH, it will always use version of npm installed with node instead of the version of npm you installed using npm -g install npm#<version>.
So your path variable will look something like:
…;C:\<path-to-node-installation>;%appdata%\npm;…
Now you have two possibilities:
Swap the two entries so it will look like
…;%appdata%\npm;C:\<path-to-node-installation>;…
This will load the npm version installed with npm (and not with node) and with the installed Angular CLI version.
If you (for whatever reason) like to use the npm version bundled with node, add the direct path to your global Angualr CLI version. After this your path variable should look like this: …;C:\Users\<username>\AppData\Roaming\npm\node_modules\#angular\cli;C:\<path-to-node-installation>;%appdata%\npm;…
or …;%appdata%\npm\node_modules\#angular\cli;C:\<path-to-node-installation>;%appdata%\npm;…
for the short form.
This worked for me since a while now.

'slc' is not recognized as an internal or external command, operable program or batch file

I am trying to get StrongLoop working on my Windows 7 machine.
I installed it with npm install -g strongloop
It threw some python errors, which seems to be expected and then execution finished.
I did the npm install npm step as indicated here: http://docs.strongloop.com/display/public/LB/Installing+StrongLoop#InstallingStrongLoop-Windows
When I try 'slc' on the command line it gives the above error. I added it to the path manually and still nothing. Even when I go right into the directory where the slc file is ({user}\AppData\Roaming\npm\node_modules\strongloop\bin) and try to use it from there it says the same thing. Like the file that was installed is not executable.
Is this the right file? Is there another one somewhere? Drawing a blank here.
This happened to me as well.
Try uninstalling strongloop like so: npm remove strongloop
Then install it again with Microsoft Visual Studio 2012.
Make sure it's installed, and run the npm command like so:
npm install -g strongloop --msvs_version=2012
Even if you see errors and warnings, ignore them and let it run until it's done.
If you still have errors you can check them in builderror.log that should be in:
C:\Users\<user>\AppData\Roaming\npm\node_modules\strongloop\node_modules\node-inspector\node_modules\ws

Ugly output when running NPM commands from Windows

I have manually installed "node.exe" (0.10.36 x64) & NPM Zip (1.4.12) under Windows 7.
When I run a NPM command (from cmd, powershell or Eclipse TCF terminals), it prints a lot of a new line with single character from this list: -\|/.
However, it doesn't with Eclipse console.
It uselessly fills the console and makes difficult to see messages, especially when running some infinite running command like "karma start".
Is there any way to remove/fix these ugly output characters ?
It's an issue of "1.4.12" and "1.4.13" versions. Switch back to 1.4.10 (1.4.11 doesn't work at all on my computer) has solved the issue.
Another solution can be to upgrade to newer versions of npm simply running npm install npm --global. If want to easy switch NPM versions, just copy "npm.cmd" and "node_modules/npm" to another directory. Then from this directory, run npm install npm. Finally, update your PATH to take this directory in priority (or remove the old npm versions).
I have the same issue on Win 10. I was previously using v0.12.7 (I did not know why I used a so "old" version) then installed v4.2.2 which makes ugly output.
To solve this problem, I uninstalled v4.2.2 from Control Panel, removed npm and npm_cache folder from %APPDATA%, and finally removed all paths related to Node and npm from PATH environment variable.
Hope this could help someone.

firebase-tools "-bash: firebase: command not found"

Excited that Firebase's hosting is now out of beta. Trying to get going with with the firebase-tools package and I've successfully installed it:
npm install -g firebase-tools
Trying to run any tool fails with
-bash: firebase: command not found
I've tried putting the following command in my .bash_profile without any luck
export PATH=/usr/local/share/npm/bin:$PATH
Any ideas? Pretty new to the command line in general.
Thanks!
Run code below with terminal,
alias firebase="`npm config get prefix`/bin/firebase"
Installing firebase-tools globally did the trick for me :
npm install -g firebase-tools
You should add the npm bin folder to your bash PATH variable. To do that, run:
npm get prefix
And it should output something like /home/your-username/npm-global or /home/your-username/npm-packages.
Then in your ~/.bashrc or ~/.bash_profile (if you're in a Mac) file, add:
export PATH="/home/your-username/npm-global/bin:$PATH" # Add npm bin PATH
Note the "/bin" after the npm get prefix result.
#mklement0 That answer looks good, but I'm worried it will be intimidating to someone who is so new to the command line. So I'm going to cherry-pick the most relevant piece of it.
#cienki Run this command to see what you should be putting in that PATH prefix in your .bash_profile file:
npm get prefix
by chance if you are using macOS with m1 chip
arch -x86_64 npm i -g firebase-tools
assuming that you haven't set the PATH
export PATH="`npm config get prefix`/bin:$PATH"
That's all and enjoy
On macOS: Use
curl -sL firebase.tools | upgrade=true bash
It worked for me
firebase -V
Using Windows 10, Bash
This worked for me:
npm get prefix // to find Path which for me it was C:\Users\User\AppData\Roaming\npm
search "Environment Variables" which located in "System Properties".
Under "System Variables", find the PATH variable, select it, and click "Edit". Click "New" and add the path found with the "npm get prefix" command earlier (which was for me C:\Users\User\AppData\Roaming\npm)
Then click "Ok"
Restart Bash
firebase --version //to check firebase version
Bruno's answer did the trick, I only needed to add a dot at npm-global in Ubuntu in .bashrc:
export PATH="/home/your-username/.npm-global/bin:$PATH" # Add npm bin PATH
Below command works for me on terminal
curl -sL firebase.tools | upgrade=true bash
This command install firebase tool for me
After installing:
$ npm install -g firebase-tools
$ firebase init
-bash: firebase: command not found
"If you are getting the above output then follow the below steps:"
For Windows Users:
type this cmd :
$ npm get prefix
C:\Users\Jeet\AppData\Roaming\npm [this is the location]
Now you have to set in enviorenment variable -> (windows+r) -> sysdm.cpl -> Advanced(tab) -> Environment Variables
-> under the System Variables -> click on path -> edit -> C:\Users\Jeet\AppData\Roaming\npm [paste] the above location -> apply - ok - ok.
Restart your bash terminal
Thanks!!!
For Mac OS Sierra:
$ sudo npm install -g firebase-tools
To stop other Node process use $ ps aux | grep node
If needed to upgrade or install emulator - $ npm install -g #google-cloud/functions-emulator
Ready to go $ firebase --version
For anyone using MacOS Catalina 10.15.2 getting the bash PATH variable fixed the issue for me.
Run:
npm get prefix
Then run:
export PATH=/Users/userid/.npm-global/bin:$PATH
Note: I recently upgraded from my old High Sierra MacBook Pro, and was confused as well.
For anyone using nvm the error could arise because you are on a different nvm version than you were on when you first installed firebase tools globally. That's what it was for me. When I restarted webstorm nvm switched to a different version.
Run nvm list to check the version you are on and run nvm use x.x.x to switch to the right version where you installed firebase tools originally.
This worked for me on Mac (same thing the others have been posting above, just for Mac):
go to your home folder in Finder (named after your user name, in my case "macbook")
press cmd+shift+dot (will reveal hidden files)
go the .npm-global/bin folder and copy its path (Finder menu -> View -> Show Path Bar, right click on the bin folder in the path bar -> "Copy 'bin' as Pathname")
open Terminal (by default the home folder) and go nano ~/.bash_profile
at the top of the file add export PATH="<cmd+v>:$PATH" (will look similar to this: export PATH="/Users/macbook/.npm-global/bin:$PATH")
save .bash_profile changes and restart Terminal, firebase command should work now
if you installing firebase-tools using
yarn global add firebase-tools
i got same error then i got answer and execute this
export PATH="$(yarn global bin):$PATH"
and then i can do firebase login pretty well
I am on Linux and installing the package with admin privileges resolved the problem:
sudo npm i -g firebase-tools
Simply reinstall node.js. This worked for me and fire command was recognized.
You forgot sudo type this
sudo npm install -g firebase-tools
problem solved.
I know most answers work for all generic 'command not found' errors. Basically by manually setting PATH variable but there's an easier way for this specific problem relating 'firebase command not found':
Try this cURL command and it will fix this issue for good and will minimise any user errors.
Install the Firebase CLI using the automatic install script
Run the following cURL command (Mac or Windows):
curl -sL https://firebase.tools | bash
Source: https://firebase.google.com/docs/cli#install-cli-windows, https://firebase.google.com/docs/cli#install-cli-mac-linux
This is for updated mac mac Os Catalina(10.15.1+) & on zsh.
Go to Terminal (vim .zprofile)
add this export PATH="/Users/Your Username/.npm-global/bin:$PATH"
Works for me!
Faced the same issue, am a newbie backend guy.
Used npm install firebase-tools
It doesn't install and you can't run.
I tried looking at the forums and here's what worked for me:
sudo npm install -g firebase-tools.
Then it asks for Permissions when you firebase login.
Am using Ubuntu.
After trying pretty much everything, only one worked for me (I'm on MacOs Catalina):
Try the following in your terminal:
curl -sL https://firebase.tools | bash
This will check the OS of your machine and then install everything else automatically and properly.
The command is from the official Firebase Documentation.
https://stackoverflow.com/a/60474459/1245341
After installing
$ npm install -g firebase-tools
Note the directory where it istalled What I did was locate the directory where firebase was installed. In my case C:\usr\local then I copied the three firebase files. I also went into the node_modules folder and copied the firebase tools folder. Then I went to my app directory in file manager and pasted the firebase files, then created a new node_modules folder and pasted the firebase-tools folder.
Now go to your cmd and run
$ firebase init
It should work
I tried a lot of things from here and from other forums, but what ended up working for me (and this is more of a work-around) was to download the binary and then open it and it set up all the firebase stuff for me.
However, I found that if I moved it after opening it once, it did not work. So first move it to wherever you want to leave it and then run the .exe.
This allowed me to skip configuring the PATH variable which was nice.
I'm on a Windows 10 Pro Education. Hope this helps someone who has a similar struggle.
Adding to Durul Dalkanat's answer,
Assuming you have executed npm install firebase-tools -g
Firstly get the output of the command of npm get prefix.
Open .bashrc file which is in the home directory and add alias <output of npm get prefix>/bin/firebase at the end of the file.
Run source .bashrc in the home directory.
Enjoy!
The alias of firebase will be the actual firebase path in the main system and this solution should work flawlessly.
if you're windows 8 user, one possible solution is to put the PATH in environment variables manualy...
On the Windows desktop, right-click My Computer.
In the pop-up menu, click Properties.
In the System Properties window, click the Advanced tab, and then click Environment Variables.
In the System Variables window, highlight Path, and click Edit.
In the Edit System Variables window, insert the cursor at the end of the Variable value field.
If the last character is not a semi-colon (;), add one.
After the final semi-colon, type the full path to the file you want to find.
For me it was: C:\Users\ 'username' \AppData\Roaming\npm
To get your path put this string in you command line:
$ npm get prefix
Click OK in each open window
I tried all the answers above, other SO answers, and GitHub answers but nothing worked. The only thing that worked for me was to save whatever was inside my index.js file temporarily somewhere else, delete the entire cloud functions folder, then reinstall and start everything from the very beginning.
After many hours trying everything the only thing what helped (on windows) was downloading and installing node again.
I found a solution.
npm i express firebase-tools
If you are admin on your PC, installing firebase and firebase-tools with -g flag should resolve the issue (the path will added to the global PATH variable) but if you are an admin, you may have to add that path yourself.
Seeking help from one of the top answer, issue this command will return the path where firebase is installed
npm config get prefix /bin/firebase
In my case the following is returned.
C:\Users\*user_name*\AppData\Roaming\npm
Copy that path (from first line) and visit this page on how to update path variable (Window + x then visit systems > Advance Settings). Here add a new entry in path and past that path there. Firebase command should work from command prompt every time without the use of alias required.

installing yuidoc under windows 7

I'm trying to get yuidoc running under windows 7... and failing.
Now I'm a nodejs noob so maybe I'm doing something wrong.
I've installed the node-v0.6.19.msi from nodejs.org (got 'hello world' running so that's good)
Then I tried installing yuidoc via npm (as described here http://yui.github.com/yuidoc/)
The npm install seems to work (lots of http GET and no big red ERR!s).
Next I tried 'node yuidoc .' but that throws a 'cannot find module'.
The node msi default install folder is C:\Program Files\nodejs\
while the npm installs yuidoc to C:\Users[username]\AppData\Roaming\npm\node_modules\yuidocjs
Weirdly, the npm install only created some empty folders. What am I doing wrong?
Ah sorry, that was my bad trying to reinstall yuidoc with npm (it errored and cleared the folders).
I now seem to have yuidoc correctly installed (lot's of files in ..node_modules\yuidocjs). But trying to run it from node.js still doesn't work.
Ah it was just me being a nodejs noob. I thought I needed to run everything from within node (also tried running npm that way at first too).
Simply running yuidoc directly from command prompt does the trick.
