How to reverse "sudo chown -R 501:20" - node.js

Ran npm i -g {library} inside my project and npm gave me an error because I didnt use sudo. instead of using sudo on a second attempt, I followed npm's suggestion to run sudo chown -R 501:20 "/Users/vorousjames/.npm" (inside my project).
now anytime I run an npm command (anywhere), I get bash: /Users/vorousjames/.npm-global/bin/npm: No such file or directory
How do I fix this so I can use npm again?

try running this in the terminal
export PATH="/Users/vorousjames/.npm:$PATH
if it works add that to your .bash_profile

Command not found when executed as sudo, but works after "sudo su"

If i try to run this command bash respond with not found error:
$ npm -v
-bash: npm: command not found
with sudo also:
$ sudo npm -v
sudo: npm: command not found
but works when I run first a "sudo su":
$ sudo su
# npm -v
6.10.3
Why this happens? how can I fix it to works with sudo command?
As #franzisk pointed out, this can be issue of the $PATH for the npm.
Try to do echo $PATH both as normal user and super user. Also run which npm as superuser. If you see any difference (for example, path to npm is not in the normal user path) make changes to your PATH variable accordingly.

fail to install electron in ubuntu

I followed the command 'npm install -g electron', the command line gives me back an error 'EACCES:permission denied, mkdir /usr/local/lib/node_modules/electron/.electron'
I tried to give permission by 'chown -R root /usr/local/lib/node_modules/*', but still doen't work?
anyone seen the problem before?
solved:
at last I found you can install it directly without root or sudo
If you are using the -g flag for global, you have to either run the command as the root user or invoke the command with sudo
sudo npm install -g electron

npm command not found error but node is installed

I installed node and npm with Homebrew a while ago, they both worked fine until today when I keep running into the npm command not found error.
When is run $ whereis node, I get nothing back
When I do $ which node, I see /usr/local/bin/node
When I do $ node -v, I see v4.4.7
When I do $ whereis npm, I get nothing back
When I do $ which npm, I get nothing back
When I do $ npm -v, I see -bash: npm: command not found
I have tried
$ brew update
$ brew uninstall npm
$ brew install npm
I have also made sure that my $NODE_PATH environment variable is set:
# In ~/.bash_profile file:
export NODE_PATH="/usr/local/lib/node_modules"
I also followed these instructions from https://himanen.info/solved-npm-command-not-found/
Nothing seems to work and I keep getting npm: command not found when I run any command in any folder with npm. Any ideas? Thanks
I had the same issue, I am using a MAC.
It was a permission issue in my case, here is what I already did:
$ brew update
$ brew uninstall npm
$ brew install npm
That didn't work for me, so I tried this:
$ sudo chmod -R 777 /usr/local/lib
$ brew postinstall node
and this linked installed node with npm, when I typed:
$ npm -v
5.3.0
Now all commands followed by NPM are working fine,
like npm install
Hope this will work for all!!
Figured out the issue. So the root of the problem was that I installed npm using Homebrew and there are some issues with what goes on under the hood with Homebrew and npm.
To fix this I did the following:
rm -rf /usr/local/lib/node_modules
brew uninstall node
brew install node --without-npm
echo prefix=~/.npm-packages >> ~/.npmrc
curl -L https://www.npmjs.com/install.sh | sh
Important!
Do this in .bash_profile
export PATH="$HOME/.npm-packages/bin:$PATH"
export PATH="$HOME/.node/bin:$PATH"
Now everything works like a charm
In mac via homebrew, when you are getting error like
Error: Permission denied # dir_s_mkdir - /usr/local/lib/node_modules/npm
or mostly getting several folder permission, don't give full permission like
$ sudo chmod -R 777 /usr/local/lib
Please use as mentioned below
$ sudo chown -R $(whoami):admin /usr/local/lib/node_modules/
What it will do, simply gives the ownership to the user (linux users also can use this).
Hint: And in mac please use homebrew for installation. Advantages of homebrew you can switch between versions, easy to uninstall, you no need to run as root (sudo), like wise lots of advantages are there, as a developer its recommended to use homebrew (https://brew.sh/). And one more thing whenever you are getting some error like permission denied or something don't, give the full permission instead of using chmod use chown.
I had the same issue, I executed following command to install node and npm - it worked perfectly.
rm -rf /usr/local/lib/node_modules
brew uninstall node
brew install node

Installed npm-sudo-fix and ran it, and no luck yet.
I am on Debian Wheezy and have npm 1.4.4.
I was facing the same issue. I ran the command below, It fixed my problem:
mkdir -p /root/.config/configstore
chmod g+rwx /root /root/.config /root/.config/configstore
The same issue happened to me, i was in root mode user#. I just get back to normal user$ and it worked. i am using Zorin OS
I was able to fix this by running:
echo prefix = ~/.node >> ~/.npmrc
and
export PATH=$HOME/.node/bin:$PATH
Explanation here:
Error installing yeoman
What does `echo prefix = ~/.node >> ~/.npmrc` mean?
npm / yeoman install generator-angular without sudo
I just fixed it in Windows. I have done three things, which one have fixed it I am not sure.
Run cmd prompt as administrator.
takeown /? this command is equivalent to chown (linux) but for windows.
cacls -cacls /E /T /G :F
simply go in $USER /Users/calvin/.config/configstore/ and make files unhidden.
it worked for me like charm. I have been trying to fix this since many days.
I had the same issue building a meanjs app on Ubuntu and I've fixed this issue using sudo instead of root:
sudo npm install -g yo generator-meanjs bower grunt
Then i could build the app without being asked for password again:
yo meanjs
sudo allows user to act as root without root login, it is more secure to use sudo instead of logging in as root.
sudo vs root - askubuntu
Although the chmod command seemed to work at first, I got a similar error later, for a different folder. But here I found this workaround which fixed that too:
sed -i -e '/rootCheck/d' "${NPM_CONFIG_PREFIX}/lib/node_modules/yo/lib/cli.js"
If yo is run as root, rootCheck will downgrade to UID 1000 (on Linux) or 501 (on OS X). This causes the permission error. But in a docker container, you might want to run as root, so you have no other option.
You need to rerun this command after upgrading yeoman. In case NPM_CONFIG_PREFIX is not defined, you can use:
export NPM_CONFIG_PREFIX=$(npm config get prefix)
the issue is that yo is not granted to use some of the nodejs modules. basically, y the problem is related to authorization of yo by node package manager "npm", to fix this run this command first
sudo npm install --global yo --allow-root

NPM modules won't install globally without sudo

I have just reinstalled Ubuntu 12.04 LTS, and before anything else i did these steps:
Installed Node via package manager with the following script
sudo apt-get update
sudo apt-get install python-software-properties python g++ make
sudo add-apt-repository ppa:chris-lea/node.js
sudo apt-get update

Tried to install yeoman, express, n, yeoman's generators globally and all of them returned the same error

I need to install yeoman and its generators without sudo not to be in trouble later on :(
Ubuntu 12.04 and using Chris Lea's PPA for install the following works for me:
npm config set prefix '~/.npm-packages'
and adding $HOME/.npm-packages/bin to $PATH
Append to .bashrc
export PATH="$PATH:$HOME/.npm-packages/bin"
For more see this answer from #passy
If you already have $HOME/bin in your path, a simpler solution is just ...
npm config set prefix ~
New node commands will now install into your $HOME/bin directory.
No need to change your path!
Since this discussion is really about reducing the security risks of running sudo, you should also be aware that any node app could potentially be installing an app name that does not match the registered node package name you think you're installing. So there is a security risk that an npm install will replace an existing system command or one you already have in $HOME/bin. If you're concerned, check the bin, and scripts properties in the package.json file of the app you're installing first.
In general, it's safest to:
(a) Place $HOME/bin last in your path so system commands are not superseded.
(b) don't include "." or any relative path in your $PATH so you don't accidentally run a command that happens to be in the current directory.

NodeJS security vulnerabilities: nodesecurity.io.
As for October 2014:
Node.js is available from the NodeSource Debian and Ubuntu binary distributions repository.
curl -sL https://deb.nodesource.com/setup | sudo bash -
sudo apt-get install -y nodejs
That's it.
Outdated answer:
The fastest way without using sudo is like described here by isaac
I strongly encourage you not to do package management with sudo!
Packages can run arbitrary scripts, which makes sudoing a package
manager command as safe as a chainsaw haircut. Sure, it's fast and
definitely going to cut through any obstacles, but you might actually
want that obstacle to stay there.
I recommend doing this once instead:
sudo chown -R $USER /usr/local
EDIT:
There are certain security concerns and functionality limitations regarding changing the ownership of /usr/local to the current user:
if there is another user on the machine who could use global npm packages - do not change the ownership of /usr/local
https://apple.stackexchange.com/questions/1393/are-my-permissions-for-usr-local-correct
https://askubuntu.com/questions/261326/is-it-safe-to-chown-usr-local
Having said that, if you want to install global module without using sudo, I don't see any better solution (from pragmatic point of view) than mentioned. Security vs easy of use is very broad topic, and there is no easy answer for that - it just depends on your requirements.
The issue was i installed node using sudo, to avoid errors when installing npm modules globally one MUST NEVER install node with sudo.
My solution was to reinstall node it this way:
Download latest stable node sources from nodejs.org #in my case node-v0.10.20.tar.gz
tar -zxf node-v0.10.20.tar.gz #uncompress sources
cd node-v0.10.20 #enter uncompressed folder
sudo chown -R $USER /usr/local
./configure --prefix=/usr/local && make && make install
One thing to note is that only taking ownership of the /usr/local folder wouldn't work in my case because node installation itself was made with sudo
Last step to install yeoman: #although at yeoman.io it says that doing "npm install -g yo" already installs bower and grunt, there are some submodules of grunt that fail, so i fixed that by installing it by itself
npm install -g bower
npm install -g grunt
npm install -g yo
npm install -g generator-angular
I solved this problem with environment variable and shell alias:
export NPM_PREFIX=$HOME/node
alias npmg="npm -g --prefix $NPM_PREFIX"
For me npm did not honor the "prefix" config setting in .npmrc.
Find the path to npm's directory:
npm config get prefix
For many systems, this will be /usr/local.
Change the owner of npm's directories to the name of the current user (your username!):
sudo chown -R $(whoami) $(npm config get prefix)/{lib/node_modules,bin,share}
This changes the permissions of the sub-folders used by npm and some other tools (lib/node_modules, bin, and share).
Here is the link for full details
https://docs.npmjs.com/getting-started/fixing-npm-permissions
According to this similar SO post: npm throws error without sudo
Looks like you might have an ownership issue with ~/.npm directory.
As with the answer in that one, try:
sudo chown -R `whoami` ~/.npm
If you're on a developping machine, you might be better off considering using nvm.
If not, you simply want to install using your favorite package manager.
Whatever the case may be, I'd recommend checking this answer on stackoverflow
Actually, I just changed the permission of a user folder that was owned by root:
sudo chown -R $USER ~/.config/configstore
Then I could "npm install" and "bower install" without sudo!
Worked fine!
using lubuntu 14.04.3, I tried changing ownership of .npm and npm prefix, updated my path, npm installed modules to my home directory without sudo but the path was incorrect so the modules like ember were not found, linuxbew solved the problem, quick setup guide here for node/npm
This issue and other caused by the same reason can be solved installing Node in user space.
You can do it just copying and pasting in your terminal
NODEJS_ROOT=${NODEJS_ROOT:-~/nodejs}
cd /tmp
wget -N http://nodejs.org/dist/node-latest.tar.gz && tar xzf node-latest.tar.gz
NODEJS_CURRENT=$(tar tf node-latest.tar.gz|head -1)
mkdir -p $NODEJS_ROOT/$NODEJS_CURRENT
cd $NODEJS_CURRENT
./configure --prefix=$NODEJS_ROOT/$NODEJS_CURRENT && make install
cd $NODEJS_ROOT
rm current 2> /dev/null # Removes current symbolic link, if any
ln -s $NODEJS_CURRENT current
Same commands can be launched also to get Node updated to latest version.
Don't forget to edit your environment. Only once, do
echo "export NODEJS_ROOT=$NODEJS_ROOT" >> $HOME/.bash_profile
echo 'export PATH=$NODEJS_ROOT/current/bin:$PATH' >> $HOME/.bash_profile
source $HOME/.bash_profile # reload your env, so you can use node right now
Check out this article as a reabout how to Install Node.js without sudo.
For a more general solution about this topic (i.e., install software locally) see dotsoftware.
just use nvm
you will be able to dynamically switch between different node versions and it is installed locally for your user. No sudo needed. Just make sure you have fully cleaned up the old node beforehand.
https://github.com/nvm-sh/nvm
In order to install Node.js and npm locally without having to use sudo open the terminal and type:
echo 'export PATH=$HOME/local/bin:$PATH' >> ~/.bashrc
. ~/.bashrc
mkdir ~/local
mkdir ~/node-latest-install
cd ~/node-latest-install
wget -c http://nodejs.org/dist/node-latest.tar.gz | tar xz --strip-components=1
./configure --prefix=~/local
make install
wget -c https://www.npmjs.org/install.sh | sh
Use NVM
I had the same "permission denied" issue. Instead of trying to fix the NodeJS installed from https://nodejs.org/en/ which installs into folders that are owned by root instead of $USER, I used NVM. node version manager.
Install it: run curl -o- https://raw.githubusercontent.com/nvm-sh/nvm/v0.39.1/install.sh | bash
Install a version of node: run nvm install 16
Use it:
nvm use 16
npm install -g yarn
Everything worked fine when I used Node installed by NVM.
The best solution I found was to install Node.js from the tar package on to user home directory & link the lib folder location. Here is what you need to do
This will install Nodejs under ~/.local/ instead of the default /usr/local/
Add this to your ~/.npmrc (create the file if it doesn't exist already):
root = /home/YOUR-USERNAME/.local/lib/node_modules
binroot = /home/YOUR-USERNAME/.local/bin
manroot = /home/YOUR-USERNAME/.local/share/man
Download the Nodejs source code from nodejs.org and install it under your ~/.local tree:
tar xf node......
cd node........
./configure --prefix=~/.local
make
make install
Create ~/.node_modules symlink. (This directory will be automatically searched when you load modules using require "module" in scripts. I'm not sure why Node doesn't search ~/.local/lib/node_modules by default.)
cd
ln -s .local/lib/node_modules .node_modules
Is ~/.local/bin in your path? Type
which npm
If it says ~/.local/bin/npm, you're done.
Otherwise, do this...
export PATH=$HOME/.local/bin:$PATH
...and add that line to your ~/.profile file, so it'll run every time you log in.
If you still encounter ownership or permission error while installing packages, then change ownership of ~/.local/ dir by running
chown -R user:user ~/.local/
Now you should be good to install packages via 'npm'
Note: ALL OF THE ABOVE COMMANDS ARE TO BE RUN AS USER. DO NOT USE SUDO OR ROOT LOGIN
NEVER EVER CHANGE THE PERMISSION OF FOLDERS UNDER '/USR/LIB/'. WILL LEAD TO UNSTABLE OS
I find Pawel Grzybek's explanations very convincing: They boil down to 3 simple sudo commands, never having to use sudo again for global npm installs:
sudo chown -R $(whoami) /usr/local/lib/node_modules
sudo chown -R $(whoami) /usr/local/bin
sudo chown -R $(whoami) /usr/local/share
