rspec-rails 2.11.1 + rails 3.2.6

Question

我在我的應用程序中使用rspec-rails 2.11.0，但是當我執行rspec spec /時會發生錯誤。這是一堆錯誤：

什麼是錯誤的？這是我的寶石文件https://gist.github.com/3280825

Answer 1

發生什麼事是你的rspec應用程序版本是不同於你在全球環境中的版本。

看來，當你執行rspec從全球正在使用的一個。

的方法，使其工作是使用bundle exec從@prusswan至極表示將執行與應用程序ENV該命令（適當寶石版本等）

而且該錯誤消息中提到嘗試bundle exec

Answer 2

由於打捆使用，儘管錯誤消息說「試一試」 bundle exec，你真的有如果你想確保只有在Gemfile/Gemfile.lock指定的寶石版本使用捆綁exec來運行它。另一種方法是使用binstubs，如here所述。
