I've been desperately trying to install modules using node.js but it always fails getting packages with npm.
I logged in as Administrator and used powershell/cmd with "run as administrator". I also had problems with the registry so I used npm set registry http://registry.npmjs.org/
I tried everything... it just drives me nuts.
Here are the errors:

It turns out that you don’t have to run the command again as Administrator, and doing so won’t fix the problem.
Try:
npm cache clean first.
If that doesn’t fix things, take a look in %APPDATA%\npm-cache, or if you’re using PowerShell, $env:APPDATA\npm-cache.
After cleaning the cache, you may still be left with remnants. Manually remove everything in that directory, and try again. This has always fixed things for me.
As #Crazzymatt was mentioning, as of the npm#5 version and up, we need to use npm cache verify instead of npm cache clean. Or else you will get an error as preceding.
npm ERR! As of npm#5, the npm cache self-heals from corruption issues and data extracted from the cache is guaranteed to be valid. If you want to make sure everything is consistent, use 'npm cache verify' instead.

I solve it running as administrator cmd.
Cleaning the cache
npm cache clean -f
And then try to install the package again
You should run cmd.exe as administrator.
Follow the following steps:
Click Start, click All Programs, and then click Accessories.
Right-click Command prompt, and then click Run as administrator.
Here is how I fixed this on my Windows (7) Dev. environment.
I assume the following...
You are Running Command Prompt, Git Bash, Cmder or your favorite Terminal, as an Administrator by right clicking
Privileges Permissions have been granted for Read/Write (i.e chmod -777)
Okay, let's get to it:
Update any packages where a version check is returning a warning ("npm WARN"..) for example...
npm update -g npm
npm update -g graceful-fs
Next we want to force a cache clean. This is flagged by an '--f' or '-f'..
npm cache clean --f
In Widows Explorer search for the following path
%APPDATA%\npm-cache
And Delete it's contents
Start a fresh instance of your Terminal, remembering to 'Right-Click' and 'Run as Administrator', install the packages again.
Hope this helps someone!!
I was already running the Node Command Window as Administrator. As mentioned by many above, the following command with --f (force) solved my issue.
npm cache clean -f
After the Cache Clean, the install was flawless. See the screenshot for reference
I had to login into npm to resolve this issue.
npm login
If you're using TFS or any other source control for your project that sets your checked in files to readonly mode, then you gotta make sure package.json is checked out before running npm install. I've made this mistake plenty of times.
I had the same problem and I've fixed the error by cleaning the cache:
npm cache clean -f
I had the same problem, what I did to solve it was ran the cmd.exe as administrator even though my account was already set as an administrator.
Try following steps
1. Run this command on Terminal or CMD - npm cache clean
2. Go to this folder on windows %APPDATA%\npm-cache And delete folder which you want to install module (Ex:- laravel-elixir) or if you are using PowerShell, $env:APPDATA\npm-cache
3. Then Run your command EX:- npm install laravel-elixir
Here is how I fixed the problem in Windows. I was trying to install the CLI for Angular.
Turn off firewall and antivirus protections.
Right click the nodejs folder (under Program Files), select Properties (scroll all the way down), click the Security tab, and click all items in the ALLOW column (for All System Packages and any user or group that allows you to add the “allow” checkmark).
Click the Windows icon. Type cmd. Right click the top result and select Run as Administrator. A command window results.
Type npm cache clean. If there is an error, close log files or anything open and rerun.
Type npm install -g #angular/cli (Or whatever npm install command you are using)
Check the installation by typing ng –version (Or whatever you need to verify your install)
Good luck!
Note: If you are still having problems, check the Path in Environmental Variables. (To access: Control Panel → System and Security → System → Advanced system settings → Environment variables.) My path variable included the following:
C:\Users\Michele\AppData\Roaming\npm
npm cache verify
Try for newer versions of npm.
I'm using v 5.5.1 and it's working fine.
This is the flow often happens in this case. You run a command with no admin rights, you get message npm ERR! Please try running this command again as root/Administrator.. Then you open one more CLI(cmd, powershell, bash or whatever) and don't close the previous CLI. It appears you have 2 prompts opened in the same directory. And until you close CLI which runs with no admin rights you will be continuously getting npm ERR! Please try running this command again as root/Administrator. So close CLI which runs with no admins rights before running a new one.
NOTE: a lot of IDE has embedded CLI(Visual Studio, VS Code etc) so please close the instance of IDE as well
For those doing this on a MAC. Simply put sudo in front of the command. It will ask you for your password and then run fine. Cheers
What helped me on Windows 10 was just ticking off "Read Only" of project node_modules.
I messed with this problem 2 times and tried all suggestions here with mediocre success.
First time I tried (and succeeded luckily) by:
delete the node_modules folder in your project
npm clean cache -f
check your %APPDATA%/npm-cache and delete everything if not empty
start the terminal as administrator (in my opinion, it isnt a problem of rights, but it wont hurt if you do so)
npm install and then npm update
you will get errors, just install every module that throws an error manually and step by step try to eliminate everything whats wrong
However, this method is quite frustrating and not working everytime. So try this:
Second time I had no luck with the steps above, so I tried to completely reinstall npm and it failed. So I thought there must something be wrong with my node.js installation. My team is running 6.10. and I had the 6.11. and tried it with the 6.10. with no luck.
So I completely wiped everything off my system. Deleted all node modules, checked every path where node or npm could be and cleaned my system.
Then I installed newest 8.1.3
Deleted my project and cloned it to a complete different directory.
Now I installed and updated everything with npm install npm update
Then I compiled with just 2 modules missing and installed them manually
Tadaaaaa, its working now. So all in all it was a problem with node.js. I recommend to everyone who runs into this problem: Try different node versions! And clean ABSOLUTE everything.
As my last resort with this error I created a fresh windows 10 virtual machine and installed the latest nodejs (v6). But there was a host of other "ERRs!" to work through.
I had to run npm cache clean --force which ironically will give you a message that reads "I sure hope you know what you are doing". That seems to have worked.
It doesn't solve the issue on my main Dev machine. I'm canning nodejs as I found over the last few years that you spend more time on fixing it rather than on actual development. I had fewer issues with node on linux ubuntu 14.04 if that's any help.
Deleting the global npm-cache and/or running my cmd line as admin did not work for me. Also, as of npm version 5.x.x, it supposedly recovers from cache corruption by itself.
This did work:
1. Deleted the node_modules folder in my current project.
2. Deleted the package-lock.json in my current project
3. Installed the new package. In my case: npm install bootstrap#next --save
4. Ran npm install for my current project.
Everything now works. In general, nuking node_modules and package-lock.json usually fix these "no apparent reason" bugs for me.
EDIT
I just had the same problem again. But I noticed that everything was installed correctly even though it threw the error after I had followed the steps outlined above. So I could just run ng serve (for Angular), and everything worked.
This sure is a weird error...
As a hack,
Check if the folder path it is complaining exists or not.
If not, try creating them manually and rerun the installation, after clearing the cache
I had success with this, when running the installation from command prompt as an Administrator didn't work
$ npm cache clean
npm ERR! As of npm#5, the npm cache self-heals from corruption issues and data extracted from the cache is guaranteed to be valid. If you want to make sure everything is consistent, use 'npm cache verify' instead.
I tried running npm cache verify with admin rights and it worked after that.
This worked for me, if your package.json is not too big you can do this:
Signout then signin.
Delete node_modules.
npm install again.
Like the other answers, clean npm cache and make sure the cache folder is empty, then run npm install several times. Each time the error message comes for different packages, and the final time (after X attempts) it succeeds.
Run npm clean cache --force
cd %APPDATA%\npm-cache (or cd $env:APPDATA\npm-cache for PowerShell)
del * to delete everything in the folder
Go back into the project folder and run npm install several times until it succeeds. Notice that the error messages come for different packages every time.
WHAT WORKED FOR ME
I ran Command Prompt as Administrator. This helped partially - as I no longer got the error, "Please try using this command again as root/administrator". I was trying to install Cordova. To do it successfully, I also had to do the following:
(1) "npm update node", plus...
(2) I also added the " -g " in the >>npm install cordova<<. In other words, type this: >>npm install -g cordova<<
~~~ FOR WINDOWS 8.1 ~~~
"RUN AS ADMINISTRATOR" COMMAND PROMPT
For windows 8.1, I don't have an ACCESSORIES group when I click START > ALL PROGRAMS. But I do have that older -- but trusty and reliable -- START BUTTON and START MENU - thanks to the free Classic Start Menu app. So, with that installed....
ALTERNATIVE #1:
1. Type "cmd" in the SEARCH BOX at the bottom of the START menu.
2. When cmd.exe shows up in the top of the search results, right click it and select RUN AS ADMINISTRATOR.
ALTERNATIVE #2 If you already have a Command Prompt window open and running - and you want to open another one to Run As Administrator:
1. Locate the Command Prompt app icon in the Taskbar (usually along the bottom of you screen unless you have moved it a different dock/location).
2. Right click the app icon.
3. Now, right click "COMMAND PROMPT" and select RUN AS ADMINISTRATOR.
Hope this helps someone.
I don't know which steps worked for me. But these are my steps to get rid of this error:
Updated Node.js
Ran npm cache clean command in Command prompt ( With
some element of doubt for cache presence)
Ran react-native init in
command prompt as Administrator (on Windows OS), hoping works well
with sudo react-native init on Mac OS
Close the IDE
Close the node terminals running ng serve or npm start
Go to your project folder/node_modules and see you if can find the package that you are trying to install
If you find the package you are searching then delete package folder
In case, this is your 1st npm install then skip step 4 and delete everything inside the node_modules. If you don't find node_modules then create one folder in your project.
Open the terminal in admin mode and do npm install.
That should fix the issue hopefully
FINALLY Got this working after 4 hours of installing, uninstalling, updating, blah blah.
The only thing that did it was to use an older version of node v8.9.1 x64
This was a PC windows 10.
Hope this helps someone.
If you're in react native project, and Expo is running, then close it.
Re-install the package, and everything should be fine.
Also remember to end all other npm commands e.g. npm run dev-server.
A solution that worked, is to close all PowerShell and cmd instances. Start PowerShell/cmd again as administrator and things seem to work.
This can happen if you're doing react-native and the node.js cmd is open in the background.
On windows 10,
npm cache clean --force and npm cache verify did not work for me.
Tried to delete cache folder and file with administrator permission, did not work.
The process-explorer tool helped me finding that Node.exe is holding on the cache file. I killed the process and tried to clean, worked.
I kept running into this error when installing Bower through NPM on a Windows 7 machine running a precise32 Ubuntu Box on Vagrant. I tried every combination of commands and always got the same or very similar errors
Installing locally, globally, with sudo, without sudo, etc.

EDIT: As well as my answer below please note the file directory + file size limitation when using Windows (260 characters I believe)
I have had to install vagrant in a folder directly on my c:/ drive to get over this limitation as some packages end up having nested dependencies causing this limit to be exceeded. My problem was with grunt-contrib-less
Self answering as I couldn't find a solution anywhere else on StackOverflow
I eventually got it to work via changing to the root user via su root and trying to install globally again. Apparently just using sudo wasn't enough.
So it became
root#precise32: npm install -g bower --no-bin-links

EDIT 2: After coming across this problem again and again I'll add a bit more information for people here regarding node modules and vagrant under Windows.
I now overcome the file path limitation via putting any long dependency chains that fail due to path length (usually EPERM) I add one of the packages in the chain to my own package.json. This means the long requirement chain is split as npm does not re-install the package deeper in the tree if it's already installed.
Just make sure you require a version which is valid for the version string for the module.
The order of the dependencies in package.json does not matter, dependencies are resolved before anything is installed
One of ops guys (vagrant and node.js quick tip) found a solution for that problem. Basically you need to have the following code in your Vagrant file:
config.vm.customize ["setextradata", :id, "VBoxInternal2/SharedFoldersEnableSymlinksCreate/v-root", "1"]
That will allow npm to create symlinks for the modules that require it.
Than install packages without forcing the symlinks. So, when running npm install on a virtual machine created through vagrant, run it as:
sudo npm install --no-bin-link
It was usefull for me when I installed the express
module.
With Vagrant 1.5 on Windows, you can now use rsync or smb folder shares which won't have this problem.
To get around the 260 character file length limit in windows, which npm seems to surpass quite easily, you can use the npm link command.
This will allow you to use node_modules local to your project. If you run it on your guest machine it will install them globally on your guest machine and then create a symlink in your projects node_modules folder. That way only the symlink is shared to the windows host machine and the 260 file length limit is not exceeded.
I go over this in more detail in this blog post here.
I can't find at all where npm has its global settings stored.

There is a problem with upgrading npm under Windows. The inital install done as part of the nodejs install using an msi package will create an npmrc file:
C:\Program Files\nodejs\node_modules\npm\npmrc
when you update npm using:
npm install -g npm#latest
it will install the new version in:
C:\Users\Jack\AppData\Roaming\npm
assuming that your name is Jack, which is %APPDATA%\npm.
The new install does not include an npmrc file and without it the global root directory will be based on where node was run from, hence it is C:\Program Files\nodejs\node_modules
You can check this by running:
npm root -g
This will not work as npm does not have permission to write into the "Program Files" directory. You need to copy the npmrc file from the original install into the new install. By default the file only has the line below:
prefix=${APPDATA}\npm
For me (being on Windows 10) the npmrc file was located in:
%USERPROFILE%\.npmrc
Tested with:
npm v4.2.0
Node.js v7.8.0
It looks like the files npm uses to edit its config files are not created on a clean install, as npm has a default option for each one. This is why you can still get options with npm config get <option>: having those files only overrides the defaults, it doesn't create the options from scratch.
I had never touched my npm config stuff before today, even though I had had it for months now. None of the files were there yet, such as ~/.npmrc (on a Windows 8.1 machine with Git Bash), yet I could run npm config get <something> and, if it was a correct npm option, it returned a value. When I ran npm config set <option> <value>, the file ~/.npmrc seemed to be created automatically, with the option & its value as the only non-commented-out line.
As for deleting options, it looks like this just sets the value back to the default value, or does nothing if that option was never set or was unset & never reset. Additionally, if that option is the only explicitly set option, it looks like ~/.npmrc is deleted, too, and recreated if you set anything else later.
In your case (assuming it is still the same over a year later), it looks like you never set the proxy option in npm. Therefore, as npm's config help page says, it is set to whatever your http_proxy (case-insensitive) environment variable is. This means there is nothing to delete, unless you want to "delete" your HTTP proxy, although you could set the option or environment variable to something else and hope neither breaks your set-up somehow.
How to figure it out
Start with npm root -- it will show you the root folder for NPM packages for the current user.
Add -g and you get a global folder. Don't forget to substract node_modules.
Use npm config / npm config -g and check that it'd create you a new .npmrc / npmrc file for you.
Tested on Windows 10 Pro, NPM v.6.4.1:
Global NPM config
C:\Users\%username%\AppData\Roaming\npm\etc\npmrc
Per-user NPM config
C:\Users\%username%\.npmrc
Built-in NPM config
C:\Program Files\nodejs\node_modules\npm\npmrc
References:
https://docs.npmjs.com/files/npmrc
https://docs.npmjs.com/misc/config
https://docs.npmjs.com/cli/root.html
Have you tried running npm config list? And, if you want to see the defaults, run npm config ls -l.
Even though we have the .NPMRC can be in 3 locations,
Please NOTE THAT - the file under the Per-User NPM config location take precedence over the Global & Built-in configurations.
Global NPM config => C:\Users\%username%\AppData\Roaming\npm\etc\npmrc
Per-user NPM config => C:\Users\%username%.npmrc
Built-in NPM config => C:\Program Files\nodejs\node_modules\npm\npmrc
To find out which file is getting updated, try setting the proxy using the following command
npm config set https-proxy https://username:password#proxy.company.com:6050
After that open the .npmrc files to see which file get updated.
Isn't this the path you are looking for?
C:\Program Files\nodejs\node_modules\npm\npmrc
I know that npm outputs that , but the global folder is the folder where node.js is installed and all the modules are.
On windows, used the below command that listed down all the default values for npm including the location of config file with variable name userconfig
npm config ls -l
