sudo: npm: command not found

Question

I had to do

sudo apt-get install npm

that worked for me.

The npm file should be in /usr/local/bin/npm. If it's not there, install node.js again with the package on their website. This worked in my case.

For MAC users, the follow steps worked for me.

If you get Error for Brew, Here's the command you need to type first in the terminal:

/bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install.sh)"

Then run following commands:

$ brew update
$ brew uninstall node
$ brew install node
$ brew postinstall 

I had the same problem; here are the commands to fix it:

• sudo ln -s /usr/local/bin/node /usr/bin/node
• sudo ln -s /usr/local/lib/node /usr/lib/node
• sudo ln -s /usr/local/bin/npm /usr/bin/npm
• sudo ln -s /usr/local/bin/node-waf /usr/bin/node-waf

** EDIT **

WARNING! - Doing a chmod 777 is a fairly radical solution. Try these first, one at a time, and stop when one works:

• $ sudo chmod -R 777 /usr/local/lib/node_modules/npm
• $ sudo chmod -R 777 /usr/local/lib/node_modules
• $ sudo chmod g+w /usr/local/lib
• $ sudo chmod g+rwx /usr/local/lib

$ brew postinstall node is the only install part where I would get a problem

Permission denied - /usr/local/lib/node_modules/npm/.github

So I

// !! READ EDIT ABOVE BEFORE RUNNING THIS CODE !!
$ sudo chmod -R 777 /usr/local/lib
$ brew postinstall node

and viola, npm is now linked

$ npm -v
3.10.10

Extra

If you used -R 777 on lib my recommendation would be to set nested files and directories to a default setting:

• $ find /usr/local/lib -type f -print -exec chmod 644 {} \;
• $ find /usr/local/lib -type d -print -exec chmod 755 {} \;
• $ chmod /usr/local/lib 755

I had to do the following:

1. brew update
2. brew uninstall node
3. Visit https://nodejs.org/en/ download the file
4. Install the downloaded file
