Answer 1

In case could be useful for anyone that uses rh-* packages this worked for me:

sudo ln -s /opt/rh/rh-nodejs8/root/usr/bin/npm /usr/local/bin/npm

Answer 2

For me, any of the methods mentioned above using Homebrew did not work on macOS. So, I uninstalled node using Homebrew and downloaded the node package from https://nodejs.org/en/download/ and installed it. It worked like a charm.

Answer 3

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

Answer 4

WARNING (edit)

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

Answer 5

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

Answer 6

For CentOS users, this works for me:

sudo yum install npm
