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