“未定义的方法’组’用于Rails：模块”在Mac上运行“rails generate rspec：install”时

$ rails generate rspec:install /Users/AlbertoRDZ/Desktop/rails_projects/sample_app/config/application.rb:7:in `': 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 `' from script/rails:6:in `require' from script/rails:6:in `' 

Answer 1

也许它适用于以下内容：

在config/application.rb替换

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

同

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