無法加載Rails應用程序與粗糙寶石

Question

我想加載使用Gruff gem的Ruby on Rails應用程序。我可以在irb中加載Gruff，但每當我嘗試加載應用程序（通過ruby script/server）時，它都會崩潰。以下是完整的堆棧跟蹤：

我該如何解決這個問題以便應用程序能夠運行？

是否需要將寶石直接安裝到您的Rails應用程序目錄中？

從here：

Rails插件

響螺很容易與Rails的使用。

gem install gruff 
cd vendor/plugins && gem unpack gruff 

如果你只是做gem install gruff這可能解釋它不是在軌工作，但在工作IRB。
