我試圖在rails 4.2中安裝rake gem。 釷寶石似乎安裝正常，但然後Rails嘗試運行時失敗，說它不能看到rake-10.5.0。 我正在開發魯米賽，我得到的錯誤在下面，我的Gemfile也是如此。 我試圖刪除Gemfile.lock建議其他職位，但無濟於事。Rails找不到Rake-10.5.0

實際上，您不需要在'gemfile'中包含'gem'rake''。嘗試刪除這個字符串並刪除'gemfile.lock'一個，'gem install rake --version = '10 .5.0''和'bundle install' –
刪除gemfile.lock的問題是你可以無意間拉入不同的寶石版本比你在prod/staging環境中使用的版本要多。此外，如果該步驟作爲部署的一部分運行，則依靠gem install來獲取「正確」版本的rake僅適用於其他環境。 – jaydel
