Require 'rubygems' > false

Hi,

I got this: Successfully installed awesome_print-1.6.1 Parsing documentation for awesome_print-1.6.1 Done installing documentation for awesome_print after 1 seconds 1 gem installed Annteki-MacBook-Pro:~ ann$ irb 2.2.1 :001 > require 'rubygems' => false

But gem 'awesome_print' true.

What can I do to have the require 'rubygems' go true? Thanks.

The return value for require doesn't actually tell you whether it loaded or not. Rather it tells you if it loaded for the first time or if it was already loaded. If it does not find something that fits the require statement it will actually throw an exception and fail. In this case rubygems is already loaded by default in your irb environment, so your return value of false is telling you that it has already loaded and no action was taken.

Already loaded

irb(main):001:0> require 'rubygems'
=> false

Not found

irb(main):002:0> require 'notagem'
LoadError: cannot load such file -- notagem
    from /System/Library/Frameworks/Ruby.framework/Versions/2.0/usr/lib/ruby/2.0.0/rubygems/core_ext/kernel_require.rb:55:in `require'
    from /System/Library/Frameworks/Ruby.framework/Versions/2.0/usr/lib/ruby/2.0.0/rubygems/core_ext/kernel_require.rb:55:in `require'
    from (irb):2
    from /usr/bin/irb:12:in `<main>'

Loading for the first time

irb(main):003:0> require 'json'
=> true
