Unable to use update npm or install any npm module on mac

Question

npm ERR! Darwin 17.2.0
npm ERR! argv "/usr/local/bin/node" "/usr/local/bin/npm" "i" "-g" "npm"
npm ERR! node v6.9.2
npm ERR! npm  v3.10.9

npm ERR! Cannot find module 'realize-package-specifier'
npm ERR!
npm ERR! If you need help, you may report this error at:

When I try to update npm this the error I receive. I get similar errors while performing any npm install/update operation.

Any idea how to resolve this issue?

Answer 1

Reinstall node via brew ( brew uninstall node & brew install node ). npm ships with Node so you should be good to go. These errors might occur after updating npm, AFAIK this is the safest workaround.

Answer 2

I installed node using nvm and my issue was resolved. This is what I followed to do so.
