使用CanCan和Twitter引導的Rails教程引導

使用Ruby version1.9.3p286和Rails 3.2.8無法運行此開源項目http://railsapps.github.com/tutorial-rails-bootstrap-devise-cancan.html.I。我已經安裝了所有的寶石成功，但試圖從RubyMine的輸出運行時執行以下操作：使用CanCan和Twitter引導的Rails教程引導

一點除了@狒狒的解決方案，嘗試刪除Gem.lock文件並再次運行bundle install

如何過，一旦你是舒服本例中，您可能會感興趣生成您的軌道骨架

試圖刪除gem.lock文件並運行軟件包安裝，但它無法幫助我，謝謝你的作曲家！ –

來自@ sameera207的好建議。使用Rails Composer來生成應用程序。並從作者的安裝Rails閱讀本文：http://railsapps.github.com/installing-rails.html –

它找不到diff-lcs-1.1.3寶石，嘗試運行包手動安裝或安裝寶石。

編輯：看到你的寶石文件，它缺少

gem "diff-lcs", "1.1.3"

我手動嘗試，但所有的t他一樣。 –

添加了gem「diff-lcs」，「1.1.3」，但現在RubyMine打印在任何源代碼中找不到multi_json-1.3.6（Bundler :: GemNotFound） –

也添加了那一個，其他任何可能會抱怨關於。 –
