brew install npm "npm: command not found"

Solution 1:

I encountered the same issue. After searching and reading different things online, what worked for me was:

$ brew postinstall node

However, first please do execute:

$ brew doctor

and follow the instructions there first, like the comment in your question mentions.

Solution 2:

Try running

$ brew postinstall node

Solution 3:

Try the following:

$ brew update
$ brew uninstall node
$ brew install node
$ sudo chown -R YouComputerName /usr/local/lib/node_modules/
$ brew postinstall node

Solution 4:

the same problem with you, I fixed by:

/usr/local/lib/node_modules/npm/bin/npm-cli.js i -g npm
