OpenSSL Errors; Mokey in the Middle attacks blah blah

My full list of nonsense upon running bundle install

$ bundle install Fetching source index from https://rubygems.org/ Retrying fetcher due to error (2/4): Bundler::Fetcher::CertificateFailureError Could not verify the SSL certificate for https://rubygems.org/.

There is a chance you are experiencing a man-in-the-middle attack, but most likely your system doesn't have the CA certificates needed for verification. For information about OpenSSL certificates, see http://bit.ly/ruby-ssl. To connect without using SSL, edit your Gemfile sources and change 'https' to 'http'. Retrying fetcher due to error (3/4): Bundler::Fetcher::CertificateFailureError Could not verify the SSL certificate for https://rubygems.org/.

Upgrading to watir 6 and selenium-webdriver 3

The Error in Console:

/System/Library/Frameworks/Ruby.framework/Versions/2.0/usr/lib/ruby/2.0.0/rubygems/core_ext/kernel_require.rb:55:in require': require "watir-webdriver" is deprecated. Please, use require "watir"

I didn't have RVM or Homebrew installed, so steps were a bit longer than expected

Open a terminal to see the list of installed rubies: rvm list

  1. See available rubies for installation: rvm list known
  2. Install a new version ruby (e.g. 2.1.4): rvm install 2.1.4

After npm init and you do all that noise, for setup
  1. npm install --save-dev webpack webpack-dev-server babel-loader babel-core

Note: insert react-hot-loader and react etc, if you are working on React projects

example: npm install --save react react-dom history react-router

  1. touch webpack.config.js and add this boilerplate:
