Fixing npm On Mac OS X for Homebrew Users

If you just want to fix the issue quickly, scroll down to the "solution" section below.

Explanation of the issue

If you're a Homebrew user and you installed node via Homebrew, there is a major philosophical issue with the way Homebrew and NPM work together. If you install node with Homebrew and then try to do npm update npm -g, you may see an error like this:

$ npm update npm -g

Problem

  • Using emmet in jsx files
  • Emmet expands text when js autocomplete needed
  • Using className instead of class

How it works

  • Install plugin RegReplace
  • Install plugin Chain Of Command
FROM ubuntu:14.04
