Please require this file from within a Capistrano recipe (LoadError)

Question

I'm using Capistrano 2 with Rails 3 project. Recently I rebuilt my gemset form scratch and now I receive error "Please require this file from within a Capistrano recipe (LoadError)" when I try to run rails server.

Detailed error message:

Which file I should require from within a Capistrano recipe?

Answer 1

The problem is with rvm-capistrano.

Correct it in gemfile. require: false

 gem  'rvm-capistrano',  require: false

This should help

Answer 2

A better solution I found, instead of removing it, to just move rvm-capistrano before capistrano:

# Deploy with Capistrano
gem 'rvm-capistrano'
gem 'capistrano'
gem 'capistrano-ext'

Answer 3

But, what's strange, I've solved this problem also like that (in my Gemfile, just to comment main capistrano gem):

# Deploy with Capistrano
# gem 'capistrano', :group => :development
gem 'rvm-capistrano', :group => :development
