Question

$ rails generate rspec:install

/Users/AlbertoRDZ/Desktop/rails_projects/sample_app/config/application.rb:7:in `<top (required)>': undefined method `groups' for Rails:Module (NoMethodError)
    from /Users/AlbertoRDZ/.rvm/gems/ruby-1.9.2-p290/gems/railties-3.0.9/lib/rails/commands.rb:15:in `require'
    from /Users/AlbertoRDZ/.rvm/gems/ruby-1.9.2-p290/gems/railties-3.0.9/lib/rails/commands.rb:15:in `<top (required)>'
    from script/rails:6:in `require'
    from script/rails:6:in `<main>'

Answer 1

也许它适用于以下内容：

在config/application.rb替换

中

if defined?(Bundler)
Bundler.require(*Rails.groups(:assets => %w(development test)))
end

与

Bundler.require(:default, Rails.env) if defined?(Bundler)
