Question

我正在关注使用rspec，capybara等覆盖TDD的this tutorial。我将以下内容添加到我的Gemfile中：

group :test, :development do
    gem 'turn'
    gem 'rspec-rails'
    gem 'capybara'
    gem 'guard-rspec'
    gem 'growl_notify'
end

跑bundle install，现在得到：

juco@jucoiMac ~/Desktop/rails-test $ rails s
    gem install minitest
    /Library/Ruby/Gems/1.8/gems/turn-0.9.6/lib/turn/minitest.rb:9:in `require': no such file to load -- minitest/unit (LoadError)
        from /Library/Ruby/Gems/1.8/gems/turn-0.9.6/lib/turn/minitest.rb:9

        from /Library/Ruby/Gems/1.8/gems/turn-0.9.6/lib/turn.rb:13

        from /Library/Ruby/Gems/1.8/gems/bundler-1.2.4/lib/bundler/runtime.rb:66:in `each'
        from /Library/Ruby/Gems/1.8/gems/bundler-1.2.4/lib/bundler/runtime.rb:66:in `require'

        from /Library/Ruby/Gems/1.8/gems/bundler-1.2.4/lib/bundler/runtime.rb:55:in `require'
        from /Library/Ruby/Gems/1.8/gems/bundler-1.2.4/lib/bundler.rb:128:in `require'
        from /Users/juco/Desktop/rails-test/config/application.rb:7
        from /Library/Ruby/Gems/1.8/gems/railties-3.2.12/lib/rails/commands.rb:53:in `require'
        from /Library/Ruby/Gems/1.8/gems/railties-3.2.12/lib/rails/commands.rb:53
        from /Library/Ruby/Gems/1.8/gems/railties-3.2.12/lib/rails/commands.rb:50:in `tap'
        from /Library/Ruby/Gems/1.8/gems/railties-3.2.12/lib/rails/commands.rb:50
        from script/rails:6:in `require'
        from script/rails:6

当我尝试执行包括rails server在内的任何rails命令时。这已经posted before，但未得到答复。

Answer 1

turn宝石是最小的。似乎你正在使用rspec，因此你有不兼容性。

Answer 2

转动宝石版 -

 group :test do
      gem 'turn', '< 0.8.3'
    end
