When I use this command in command mode:
D:\xampp\htdocs\profileApp>npm run dev
I get this error:
'npm' is not recognized as an internal or external command, operable
program or batch file.
How can I solve this?
First of all, I assume you are a Windows user. In this case, you need to download and install NPM together with NodeJS from the official website. When installing, do not unselect the "Add to PATH variables" point. It's important that NPM is added to your PATH variables, so it's globally available.
After installing, simply restart your terminal(s)
Download and install Gitbash it will be used to run such commands. `
Git bash will help you emulate bash commands. Read this article with how to use git and npm on windows with Git Bash
First you need to install Node which comes with NPM bundled in so that it would be recognizable by Windows CMD you can download the latest version from the Official Website.
Optional : If you are willing to work on open source projects consider
installing Git for windows
When I install node 0.10.33 from the msi ( http://nodejs.org/download/ ), I get an old version of npm (1.4.28). How can I upgrade npm on Windows?
npm install -g npm
does not work; I still have the old npm.
You need to follow the Windows upgrade instructions ( https://docs.npmjs.com/try-the-latest-stable-version-of-npm )
tl;dr - npm -g install npm does work, but the old version of npm is still in your PATH.
To fix this, do one of these:
Option 2: remove both of
C:\Program Files (x86)\nodejs\npm
C:\Program Files (x86)\nodejs\npm.cmd
Or
Option 3: Open cmd.exe as administrator, navigate to C:\Program Files (x86)\nodejs and
then run the installation without -g:
npm install npm#latest
*There is an npm package that automate this Option 3:
npm install -g npm-win-upgrade
We at Microsoft Open Source wrote a small tool to automate the process outlined above. You can find it here or just install and run it by executing the following in an elevated command prompt / PowerShell:
npm install -g npm-windows-upgrade
npm-windows-upgrade
There May be many ways to update your npm in Windows
Way 1
Open you power shell as Administrator and run following commands step by step.
Set-ExecutionPolicy Unrestricted -Scope CurrentUser -Force
npm install -g npm-windows-upgrade
npm-windows-upgrade
Here you can select your preferred version of npm
Ready to go !
Way 2
You can simply upgrade to the latest npm version with following command
npm install npm#latest -g
or if you want a specific version of npm simply run
npm install npm#{version} -g for example npm install npm#3.3.12 -g
Now simply run npm --version or npm -v to know your current version of npm
3.3.12 is my preferred version of npm that best suits for approximately every package.
UPDATE
npm install npm#latest -g
the correct npm version is now already shipped with node.js so you can directly switch node version.
you can nvm (Node Version Manager) package to switch node versions very quick and easy.
So, TL;DR; this worked:
Uninstall node
From a command prompt, run where npm
If you had npm installed via chocolatey, you'll see a path like C:\ProgramData\chocolatey\bin\npm.exe - DELETE it!
Now install NodeJS using the appropriate MSI from https://nodejs.org/en/download/
In your favourite shell, type npm --version - this should now echo the version of NPM that came with NodeJS (at the time of this writing, that version is 3.10.10)
This is what worked for me (goofy me!)
I had (age ago) installed npm via chocolatey, which created a chocolatey initiated npm.exe in C:\ProgramData\chocolatey\bin\npm.exe. This was npm version 1.4.9 and wouldn't update no matter what one did including uninstall and reinstall NodeJs.
=======
EDIT: Better way to install node and npm
As of today (27/06/2017), the best way to install and manage node and npm is to install nvm (Node Version Manager) as explained here: https://github.com/coreybutler/nvm-windows. Once you have nvm, installing any node version is super easy:
Open your favourite console (CMD, Cmder, PowerShell)
Type nvm install 6.10.2 (to install node version 6.10.2)
To see the currently active version, type nvm list. This prints something like below:
6.9.3
* 6.9.2 (Currently using 64-bit executable)
6.9.1
6.10.2
It's late 2021 and a lot of these answers can be confusing. npm install -g npm can break your installation. (When I did this, I had to run the Node MSI "Repair" tool to get it working again.) npm-windows-upgrade has not seen a release in over 2 years, and the repo has been archived by its maintainer.
As far as I can tell, there are two options that seem to work reliably today.
Use where npm from DOS prompt or which npm from WSL / Git Bash / etc, to determine which NPM binary is being used.
cd to that path, then run npm install npm#latest (without the -g flag!). npm update npm should have the same effect. You may need an elevated prompt (Run As Administrator).
Verify that this worked by running npm --version.
This worked for me. The other option is:
Completely uninstall NPM + Node using the Add/Remove Programs settings page.
Install an MSI from the Node website.
To upgrade NPM on windows 10
Uninstall Node.js
Restart your system
on command prompt type where npm
delete if npm and npm-cache folder exists in AppData/Roaming
Install Node.js (https://nodejs.org/en/)
You need to follow the Windows upgrade instructions
https://www.npmjs.com/package/npm-windows-upgrade
First, ensure that you can execute scripts on your system by running the following command from an elevated PowerShell. To run PowerShell as Administrator, click Start, search for PowerShell, right-click PowerShell and select Run as Administrator.
Set-ExecutionPolicy Unrestricted -Scope CurrentUser -Force
npm install --global --production npm-windows-upgrade
npm-windows-upgrade
Want to just install the latest version?
1.npm-windows-upgrade --npm-version latest
I did something similar to Sam Mikes. I'm only sharing this because I couldn't get either of his solutions to work on my rig. After a bit of playing around, this is what worked for me:
Remove NPM/Node from your Environment Variables, both for user and system.
Close your open console if you have one open, then open a console as administrator
Change directories to %USERPROFILE% -- that's a window's environment variable that takes you to C:\Users\CurrentlyLoggedInUser
Run from the console in %USERPROFILE%, "C:\Program Files\nodejs\npm" install npm -g (you might have yours in the x86 folder)
If this solution would work for you, step 4 would have worked, and npm -v will show a an up-to-date version
Re-add Node (in Program Files)/NPM (in App Data -- the one installed in Program Files should be the old one) to your user and system environment variables
Note: I've used the Microsoft automated script in the past to fix this, but only because I didn't realize how easy it would be to do it myself.
So none of the previous answers solved the issue for me so I thought I would post my specific solution, which I managed to figure out by going through all the other answers so they were really helpful.
My issue was because I had used chocolatey to install node and possibly npm (looking at chocolatey site now I shouldn't have done that).
To solve the issue I simply had to run the relevant choco uninstall commands for npm and node and then everything switched to the other version of node which I had also installed using the node msi (from node's website).
I hope that helps anyone else that may have gone down the same path as me.
I tried almost every answer but none of them works my way.
Neither npm-windows-upgrade worked nor did the npm install npm#latest etc etc worked.
For people like me I will suggest you guys downloading the latest installer from Node.js website, let the existing version of node directory be on it's place and without changing anything just install the msi installer and you will end up with an upgraded version of node.
My case was upgrading node from 6 to 8.9.3
all npm install commands were getting stuck and will throw error (behind proxy error) after sometime. setting up proxy was not helping. This is what I did.
Had 8.11 nodeJS
Uninstalled NodeJS from Programs & Features with the uninstaller.
Reboot (or you probably can get away with killing all node-related processes from Task Manager).
Look for these folders and remove them (and their contents) if any still exist. Depending on the version you installed, UAC settings, and CPU architecture, these may or may not exist:
• C:\Program Files (x86)\Nodejs
• C:\Program Files\Nodejs
• C:\Users{User}\AppData\Roaming\npm (or %appdata%\npm)
• C:\Users{User}\AppData\Roaming\npm-cache (or %appdata%\npm-cache)
• C:\Users{User}.npmrc (and possibly check for that without the . prefix too)
Check your %PATH% environment variable to ensure no references to Nodejs or npm exist.
If it's still not uninstalled, type where node at the command prompt and you'll see where it resides -- delete that (and probably the parent directory) too.
Reboot, for good measure.
Installed 6.11 nodejs then it worked.
Use npm-windows-upgrade tool to simply upgrade. Steps are provided in the link.
For update node npm on Windows
I have to delete node in:
C:\Users**YOUR USER**\AppData\Roaming
And reinstall node
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.
I am trying to get to grips with node.js, this looked like a fun tut http://net.tutsplus.com/tutorials/javascript-ajax/how-to-scrape-web-pages-with-node-js-and-jquery/ but I have only got the native windows version of node.js and I can't find a way to install any packages.
I have also looked at installing the binaries using chocalatey, but my version of vista doesn't have access to powershell. However, I do have a machine running windows 7 that I can switch to. If it isn't possible to install packages on windows version, I will switch to that machine and work through chocalatey.
Assuming you have the node.exe for Windows, npm has experimental support for windows. You can try working through the README.
Otherwise you can manually install packages on Windows. You will need to manually look at the package.json files for dependencies if you are going with option 2.
I have never tried it, but Scott Hanselman also has a post about getting node running on Windows.
Personally I have found its easier to just run a Linux VM since Windows support is kinda spotty right now.
The short answer is if you have git properly installed, you can open a cmd window, navigate to the directory containing node.exe, and run this:
git config --system http.sslcainfo /bin/curl-ca-bundle.crt
git clone --recursive git://github.com/isaacs/npm.git
cd npm
node cli.js install npm -gf
The more complete answer is that I posted a guide on how to install Node on Windows here. It also describes installing npm to manage packages. Let me know if it works for you.
I have XCode and NodeJS installed but can't use npm.
Here is how I installed npm:
curl http://npmjs.org/install.sh | sh
but when I try to install a package like express it doesn't response and my command line goes to "just type" mode that I just can type characters including enter.
I'm trying to install express with this command:
npm install express
This is a known issue in node, not npms fault. Try this:
npm install express --registry http://registry.npmjs.org/
Basically, https is partially broken in the newest versions of node.
