Answer 1

If you're using a Mac, perform the following steps, to remedy (assuming you have Homebrew installed already):

sudo rm -rf /usr/local/{lib/node{,/.npm,_modules},bin,share/man}/npm*

(to overcome bash: /usr/local/bin/npm: No such file or directory error):

hash -r 

Then go ahead with updating brew (to keep its kegs up to date) and the reinstallation process, linking is optional.

brew update

brew reinstall node

brew link --overwrite node

At any point inbetween you can use npm -v or node -v to test whether or not you are making progress. If you have node returning a version, but not npm then you will need to add your path to your environment with:

export PATH="/usr/local/bin:$PATH"
