Rails 4: cannot install rubyzip

Question

I am trying to install rubyzip into my Rails 4 app, but I keep getting cannot load such file errors. Here are the things I've tried:

1. A. Gemfile: gem 'rubyzip'
   B. bundle install
   C. ...Using rubyzip 1.1.4...
   D. In my controller: require 'zip'
   E. Error: cannot load such file -- zip

2. A. Gemfile: gem 'rubyzip', "~> 0.9.9"
   B. bundle install
   C. ...Installing rubyzip 0.9.9 (was 1.1.4)...
   D. In my controller: require 'zip/zip'
   E. Error: cannot load such file -- zip/zip

Not sure where I'm going wrong.

Answer 1

Figured it out. Had to restart my server and then it worked.
