Crash on loading rails

[nagi]

To recreate:

With Bundler version 1.8.3, Rails version 4.2.0. I don't know if it's relevant, but I'm not using rvm.

rails new foobar
cd foobar
echo "gem 'capistrano', '= 2.15.4', group: :development" >> Gemfile
echo "gem 'rvm-capistrano', '= 1.5.6', group: :development" >> Gemfile
bundle install
bundle exec capify .
bundle exec rails console

Possible Workarounds

1 - Switch the gem load order so rvm-capistrano loads first:

gem 'rvm-capistrano', '= 1.5.6', group: :development
gem 'capistrano', '= 2.15.4', group: :development

2 - Don't require 'rvm-capistrano` in Gemfile

Although I'm not sure what the implications of this are.

gem 'rvm-capistrano', '= 1.5.6', group: :development, require: false

If you need any more info just shout.

Many Thanks,

I had this problem several times and fixed it by setting require to false. I don't know if everyone has this issue, but if so, shouldn't the require: false part be added to the readme?
