I have a Linux server that runs some virtual Machines using KVM. Host machine is a Debian derivate with kernel 2.6.32-32(-pve).
In roughly 75% of the times I run npm install, it hangs while installing modules. I ran it in silly debug level and it always hangs at the line
npm info postinstall [module name] (older npm versions)
or
npm verb unlock done using [...] (newer npm versions)
forever.
It happens in every project on the host machine and on the virtualized systems for every node and every npm version I have tested (a lot, including the newest ones (2.7.x atm)).
It also is not deterministic. Sometimes it works, sometimes not and most of the times it hangs on a different module.
On my dev machine (which is in the same network, running OS X 10.10) it works fine.
I am not behind any kind of proxy.
What could possibly be wrong here?
EDIT: For the time being I solved this problem by checking in all my dependencies as gzipped files using https://github.com/JamieMason/shrinkpack
I was having the same issue for several hours, and couldn't work out what the problem was. I tried re-installing everything a few times, manually installing individual modules, switching from x64 to x86 versions of NodeJS, etc, and got nowhere.
In the end, I changed networks, from WiFi over ADSL2+ [~2mbps] to 4G Hotspot [~20mbps] and it worked in 30 seconds. No idea why, since it didn't seem like a network speed issue, but it solved the problem.
Hope this helps someone else, too!
I had the same problem on our Jenkins slaves based on Ubuntu, and it was solved by upgrading npm.
Default npm installed by apt-get has version 1.3.10 now, which is very old (shown by npm --version). There are at least two ways to upgrade it:
Run sudo npm install -g npm command. If you want to install a specific version you can run append it at the end of command: sudo npm install -g npm#2.1.3.
Or you could add NodeSource repositories using these instructions and run usual sudo apt-get update.
I have the same problem on Windows. I deleted my npm-cache folder and reinstalled npm. Everything started working normally after that.
The npm-cache folder can be found at
<your-drive>\Users\<your-name>\AppData\Roaming\npm-cache
Remember to turn on 'View hidden files because the AppData folder by default is hidden
You can reinstall npm by using the command,
npm i npm -g
On Windows make sure you are in a native CMD (not in VSCODE or whatever IDE). Also, try increasing the max memory limit for node:
set NODE_OPTIONS=--max_old_space_size=8096
I did the same, switched my network from WiFi to 3G and it worked.
I'm experiencing the same problem, this is the issue on Github:
https://github.com/npm/npm/issues/7862
There are some useful tips that seemed to help a few people.
For me doing $ npm install -g node-gyp (as suggested here: http://gangmax.me/blog/2013/05/13/resolve-npm-update-node-gyp-hung-problem/) fixed the problem.
I had the same problem and just run
npm cache clean
And it works!
Had this same problem in Windows. The solution was to restart after installing node and npm and then run command prompt as administrator.
In my case, a system restart did the work.
I ran npm install --verbose which suggested some lock on a file in npm-cache. And I think the system released the file (which was under use) after the system restart. I am using windows.
Try cloning the project again and then run npm install to install the packages in your terminal.
I ran into this with npm v6, and it turned out I was just being impatient. I just needed to wait a little longer and it proceeded to the next step.
npm cache clean --force
works for me :)
=> this method working with me When npm block in installation Package for IONIC installation and ReactNative and another package npm.
you can change temporary :
npm config set prefix C:\Users[username]\AppData\Roaming\npm\node_modules2
change the Path in Environment Variables set C:\Users[username]\AppData\Roaming\npm\node_modules2
Run the your command to install your package .
open file explorer copy the link C:\Users[username]\AppData\Roaming\npm\node_modules
ok file yourpackage.CMD created another folder Created "node_modules2" in node_modules and contain your package folder.
copy your package file CMD to parent folder "npm"
copy your package folder to parent folder "node_modules"
now run npm config set prefix C:\Users[username]\AppData\Roaming\npm
change the Path in Environment Variables set C:\Users[username]\AppData\Roaming\npm
now package working correctly with Command line

I just upgraded to node version 9.0.0 and am now getting this error in the command line when trying to use npm install
npm ERR! code MODULE_NOT_FOUND
npm ERR! Cannot find module 'internal/util/types'
I'm using:
OSX 10.10.5
Node version 9.0.0
NPM version 5.5.1
Extra information: I am also trying to do this with a Laravel 5.5 project. This is how I update my version of node: How do I update Node.js?
run
rm -rf /usr/local/lib/node_modules/npm
and then re-install Node.js will work in most cases
Leaving this here for anyone using the n nodejs version manager:
$ n 6.12.0 # Go back to a stable release
$ npm install -g npm#latest # Update npm to latest
$ n lts # Get 8.9.1
$ npm install #Should work now.
The MODULE_NOT_FOUND error seems to happen when changing between node versions and some files are possibly still being cached. I am not sure exactly but the above sequence of commands work for me.
When I first got this, I solved just running "npm install" again to make sure everything was installed.
I got similar error also on Windows 8 after I have just upgraded node js. First: how I ran into the issue then the solution that worked for me.
How I ran to the issue:
When I did npm --version and node --version I discovered that I wass running npm v3.x and node 5.x. So I went to nodejs.org site from where I downloaded node-v8.11.3-x64.msi. After installing the msi package I confirmed that my nodejs version was now v8.11.3 via node --version command.
Then, when I ran "npm install http-server" (w/o the quotes) that's when I got the issue:
npm ERR!
node v8.11.3
npm ERR! npm v3.5.3
npm ERR! code MODULE_NOT_FOUND
My resolution:
I did some research including on the internet and found out that the npm version pointed to in my path was the one in my roaming profile C:\Users[myname.hostname]\AppData\Roaming\npm. In other words, the npm being used is not the one in the updated package I have just installed which is located in C:\Program Files\nodejs.
The resolution was to delete npm and npm-cache in the roaming folder. Note, I used cygwin as I was not able to delete these folders via Windows cmd prompt. With cygwin, I navigated to
cd "C:\Users[myname.hostname]\AppData\Roaming"
Then I removed the aforementioned folders like so
rm -rf npm-cache
rm -rf npm
After that, I opened a new Windows cmd prompt and was able to now successfully install http-server like so:
npm install http-server
Hope this works for you.
For me it was package installation issue, so I just write,
npm i or npm install in the root of the application.
to open the terminal in the root of the application, if you're using VS-code right click on the package.json and click on Open in integrated terminal.
I founded this problem too, so I found that I have imported wrong module instead of express module I had imported router module after I had replaced this two my code work as well
If all the above solutions doesn’t work check for any blank spaces in your folder/file where you copied the path
Make sure you are inside the project folder.
Rename the folder "node_modules" to any other name (for example: node_modules_old).
Run command: "npm i" (the command will build new the folder node_modules).
Try running your program again.
If the problem is resolved and your program is running correct, delete the old folder node_modules.
If you are using libraries make sure to install everything with npm or yarn before starting. And in cases of you files if you are going to use them make sure to do the export.module thing everytime.
If you are working with Local modules then don't have node_modules. All things go well in a easy way.
But if you want to work with both local and node_modules then use
.mjs (extension) - For modules
.cjs (extension) - For common scripts which you want to run with node
in which you can use require statements like
var http = require('http');
var fs = require('fs');
but if using .js extension then use
import http from "http"
import fs from "fs"
And also your package.json for type
Haa well, I have spent two days on this and have done everything I can to fix this issue even tried resetting the system but none of them reloved the issue.
And accidentally found out what was causing this issue, it is because of & in my parent folder name. File hierarchy R&D>remix>blog, When I was trying to run the blog server it was throwing module not found, require stack error.
code: ←[32m'MODULE_NOT_FOUND'←[39m,
requireStack: []
Solution: I have changed the parent folder name to RnD and it fixed the issue. If the file name contains any special characters(even parent folders) try updating it. In my case, it is &
The MODULE_NOT_FOUND error happened to me and even running npm install the error persisted.
Try to do this
For me, what worked was deleting the node_modules folder
rm -r -f node_modules/
After that, run the command to install the package.json dependencies
npm install
What happened to me was that when I ran npm install for the first time I had a very low internet connection and therefore I believe that the packages from package.json were not downloaded correctly and due to that the MODULE_NOT_FOUND error occurred. The funny thing is that just running the npm install command has no effect because it understands that the package is already there but it isn't. Similar as a corrupted data. In my case the npm update was without effect too.
If when you are using React And getting this error message. You can use this ,
NPM
npm install #reduxjs/toolkit
Yarn
yarn add #reduxjs/toolkit
I have an Electron app that I'm trying to install node modules for. When I run npm install, it creates the node_modules folder but all the modules go into a subfolder called .staging. Each module also has -xxxxx appended to it, where the x's are some random alphanumerics.
Other Electron apps I've created have never done this. All the node modules sit in the root of node_modules and don't have -xxxxx appended.
Any idea why this is happening?
I was also facing the same issue, I tried the steps below:
Delete package-lock.json
Delete Node Modules folder
Try installing it using below command (should be in open network)
npm install
Note: - ".staging" means, those dependencies are getting downloaded so for the temporary basis it keeps all those dependencies under ".staging" folder. Once all gets downloaded properly then it will showcase them under node_modules only.
I hope this will work.
This only happens temporarily until the modules are downloaded and installed. Node seems to do this so it can place together common submodules from all the modules you are installing so it can better structure the node modules folder(mainly for windows users).
If this is happening after an npm install finishes it is likely that there is something wrong with your node installation or something in the install failed.
If you're automatically installing node_modules using CI/CD you should check out npm ci. Also check out this Stackoverflow question.
npm ci
The documentation points out the differences between npm install and npm ci.
The project must have an existing package-lock.json or npm-shrinkwrap.json
If dependencies in the package lock do not match those in package.json, npm ci will exit with an error, instead of updating the package lock.
npm ci can only install entire projects at a time: individual dependencies cannot be added with this command.
If a node_modules is already present, it will be automatically removed before npm ci begins its install. This is nice, because it prevents having to do something like rm -rf node_modules.
It will never write to package.json or any of the package-locks: installs are essentially frozen.
.staging is a temporary npm folder, where the modules are temporarily saved while they are being downloaded, if the package.json downloads are still not completed, the created folder remains, until the installation is complete.
The problem may be lack of space on your hard drive.
I was having 2 versions of node installed on my system.
nodejs v4.2 and node v8.6
I thought this could be conflicting, so I deleted nodejs v4.2 with following commands.
sudo apt-get remove nodejs
and linked the path with
sudo ln -s /usr/bin/node /usr/bin/nodejs
Again I ran npm install and it got fixed
Delete package.lock.json
Delete node_modules
run npm update
This worked for me
I moved the project from C drive to other drive and ran the following commands
take a backup of older node modules if you are running this and existing project
npm cache clean --force
npm update
I faced similar issue and tried the above answers but it did'nt worked for me;
I followed below steps to resolve this issue-
1.npm audit
By running npm audit I got list of pending packages to install-
2.npm i packagename
After installing one or two package one by one from list, I used
3.npm install
At this time the installation went smooth without any lag or hangup. Hope this help who is facing similar issue :).
Sometimes the cache is corrupt and also unremovable.
This fixed the issue I was experiencing.
If you are using nvm
Get the current node version node --version
nvm uninstall (that version)
nvm install (that version)
nvm use
npm install
If you have a windows machine where you do not posses Admin rights to it.
Try deleting node_modules and install using 'npm install' from command line as
'ADMINISTRATOR'
It works!
Anyways, it comes down to an open network thing ;)
I am facing challenges while creating package for all the clientside components of my project in a system which does not have internet connection (for windows).
I have installed NPM for windows in the system. I need to manage the node_modules and run gulp commands in the system to create the package.
Since there is no internet connection in the box, I decided to copy the node_modules from my local box to the box which does not have internet connection.
For copy task, I am using msbuild script but somehow it is not working for me. Also, I see that when I am trying to copy the node_modules manual from one folder to another folder I am unable to copy.
Installed Node version : v0.12.2
NPM version: 2.7.4
Can anyone help me to provide any working sample to fix the above problem.
I think your approach is generally sound. You can build on the internet connected computer no problem! Copy files over with a usb stick if you like.
Here are some tips that might help solve your problems.
If the box is offline, develop on your local machine and deploy to the box
If possible do the gulp steps also on your local machine
Otherwise you need to run the local directory install of gulp. e.g.
node node_modules\gulp\bin\gulp.js build
because you won't be able to npm install -g gulp
Point 3 will work for other global npm_modules too btw
If you are facing long paths (> 256 characters) which can cause copy problems
Try using npm dedupe to remove duplicates
Or try copying to a shorter path e.g to c:\proj instead of to c:\very\long\path\proj
Or explicity install a dependency which has a long path
e.g
npm install deepdep#1.2.4
and then prune that folder from the original
rm node_modules\package\node_modules\package_with_too_many_nested_folders
Or Install the latest npm (v3.0 or higher) which solves this issue once and for all
e.g. npm install -g npm
which will build a much flatter hierarchy for your packages. Requires removing and reinstalling all packages.
Point 5 is a notorious issue on windows which is not a problem on linux because paths can be extremely long. (unless you are mounting a windows a windows directory from linux)
Personally I would go straight for the latest npm version but you have a number of ways of getting around the issue if this is not possible.
searched, and did not see this specific problem.
Trying to get a MEAN stack built on my Linux Mint machine, and bumping into a bit of an unusual issue.
Got MongoDB installed, and finally got it running correctly (none of the instructions ANYWHERE mentioned having to create the /data/db/ directory and set permissions, go figure).... it works now.
Got NodeJS installed, and it appears to work correctly.
I had been told (apparently incorrectly) that NPM installs right alongside Node, with:
sudo apt-get install nodejs
but:
$ npm
bash: /usr/bin/npm: No such file or directory
So I go ahead and install NPM separately.
$ sudo apt-get install npm
Seems to work, so far, no errors, and it looks like it is pulling down the NPM package and installing it...
$ nodejs -v
v0.10.21
$ npm -v
$
?? It simply fails to respond without any error... so I try:
$ npm install grunt -g --save-dev
$
Same completely silent failure... in fact, NOTHING I could do gets a response out of NPM.
Looked all over the web, and saw nothing similar anywhere... found out that NPM holds its cache files in ~/.npm and noticed that this folder didn't exist (kinda like the mongo issue above), so I created it, and set permissions to 7777... still nothing.
Purged and re-installed both node and npm, tried installing them both together and separately (yes, desperation)... still no love.
WTF am I doing wrong?
I would love, eventually, to have a nice development environment setup, hopefully with Cloud9 as a local IDE.... but already pulling my hair out.
=========================================================================================
OK, after a few more headaches, this is up and built now... thank you all.
Would love to mark both as answers, but it won't let me.
npm does come with node. Where is apt-get pulling it from? I install the Mac OS X packages on my Mac for development and npm does in fact come with it. I compile from source on my CentOS server and npm comes with it.
Your package provider may be providing them separately as a (in)convenience to you.
As for why your npm command does not work after installation, I can't say for sure, but I am suspicious of your use of --save-dev and -g together.
-g means to install globally, which means 2 things:
It will be installed outside of your npm package's structure into a system location like /usr/bin or /usr/local/bin
It requires root access to install. Did you use sudo to run it with root access?
Both of those requirements conflict with --save-dev which records the package as a dependency in your package.json file so that future npm install commands will install that package within the project space.
That said, I happen to know a lot about grunt. It has 2 parts, a globally installed tool and the package-specific tool. The correct way to install it is:
$ [sudo] npm install -g grunt-cli
$ npm install grunt --save-dev
This will install the grunt-cli package into a system location guaranteed to be in the $PATH, which turns around and looks for a package-specific grunt installed which is not system-wide.
When installing nodejs with npm, this one-liner worked for me.
sudo apt-get install nodejs nodejs-dev npm
I don't believe npm comes with the nodejs installation in the apt repo. Try to install npm separately using the following tutorial http://www.giantflyingsaucer.com/blog/?p=1688 'To install NPM ....'
====== Edit ====
node and npm IS separate. Follow the official wiki and everything should be fine
Node noob here.
I had previously installed both npm and node separately.
Apparently, npm comes with node now. (link)
To my newbie mind, this means my previous dual installation is old and ugly. 1 binary > 2 binaries. So i uninstalled both.
Then I installed the latest node following the procedure. (i am running eOS)
Terminal
user#box:-$ which node
/usr/bin/node
user#box:-$ node -v
v0.10.22
user#box:-$ which npm
user#box:-$ npm -v
bash: /usr/bin/npm: No such file or directory
I can always run:
curl https://npmjs.org/install.sh | sh
but that seems to indicate that npm is actually NOT included in node.
When they say they are included do they just mean the code is in the same repo, but the binaries are still different?
Final question I have /usr/bin/node as well as /usr/bin/nodejs
can i delete one of these? im not sure when/where i picked up a second copy.
Yes, the nodejs package includes both node and npm executables. The code for each has its own repo, but when packaged both are included.
npm source: https://github.com/isaacs/npm
node source: https://github.com/joyent/node
When you install that .deb file from the PPA, you should get both /usr/bin/nodejs and /usr/bin/npm and 2 symlinks at /usr/bin/node (which points to) /etc/alternatives/node (which points to /usr/bin/nodejs).
If any of this isn't true, your install didn't fully succeed, most likely due to conflicting files you left around from your manual install. I would suggest uninstalling the .deb then making sure there are no stale files left from your manual install and then installing again.
Only node.js packages comes with npm. so if you are installing using an .msi, .exe, .dmg .pkg, .deb or using a package installer like apt-get, yum or brew, then you'll have both node and npm.
However,npm is not part of the node core. if you are installing node and using a method where you are using ./configure or make install || make link, then npm will not be installed, and will need to be compiled using the same type of installation, and node will have to be placed on your path.
If you used git, or unzipped node and you can see a configure script, then you will also need to acquire npm.
I've had issues (mostly on Mac) with npm ending up in directories that aren't in the terminal PATH. If you can figure out where npm is located, you can just add it to your path with something like:
export PATH=$PATH:/path/to/npm
I think (I'm not on a mac so I can't check at the moment) that it sometimes gets put in /usr/local/share/. But at any rate, the problem is likely NOT that npm isn't installed, but that it's installed somewhere you're not expecting.
Few months ago i had started learning the react so all this stuff i needed to install my laptop that had the ubuntu operating system.
What i did -- First i installed the node and without knowing that it came up with the npm package. I installed the npm package again.. but there was no conflict at all.
But after exploring all these things that nodejs have npm package. So i uninstalled the npm package due to concern about memory usage..
And Now everything is working fine....
