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

	npm --version #2.1.11

	npm install -g npm@latest

	npm --version #2.7.3

	# if npm ERR! UNABLE_TO_VERIFY_LEAF_SIGNATURE
	npm config set strict-ssl false

	# In your test_helper.rb
	class ActiveRecord::Base
	mattr_accessor :shared_connection
	@@shared_connection = nil

	def self.connection
	@@shared_connection \|\| retrieve_connection
	end
	end

	class Meal

	def initialize(meal_cost, tax_rate, tip_rate)
	@meal_cost = meal_cost
	@tax_rate = tax_rate
	@tip_rate = tip_rate
	end

	def calculate_percentage_rate(amount, rate)
	return amount.to_f * rate/100
