bundler and ruby 1.9.2

Why am I not able to use these lines in a Gemfile:

gem 'date'
gem 'pp'

Must these be required in file instead like this:

require 'date'
require 'pp'

Or is there a way to mix them into your Gemfile so they are available project wide?

I think that date and pp are part of ruby 1.9.2 core and as a result are different from regular gems but I don't exactly understand why...

Solution

  • Because those are not Gems but part of the Ruby standard library. But the standard library isnt loaded by default, hence the require statements
