升級到Rails 4.2後，我很興奮嘗試新集成的Web控制檯，但我遇到了一些問題。Rails 4.2網絡控制檯問題
在Rails 4.2的發行說明中，它提到：「使用Rails 4.2生成的新應用程序現在默認帶有Web Console gem。」
由於我升級到4.2，我認爲這意味着我仍然必須在我的Gemfile中指定它。沒有把它添加到我的Gemfile中，rails只是給了我「未定義的局部變量或方法`控制檯'」，所以我認爲這是事實。
一旦我加入的寶石 'Web的控制檯'， '〜> 2.0' 到Gemfile中，並運行Rails服務器，我現在得到：

我用Google搜索周圍，並沒有找到太多。任何意見是極大的讚賞。
謝謝！
你做捆綁舞蹈來完成升級？你有沒有'耙路軌：更新'？ – Doon
還有一個關於web_console和better_errors現在正在運行的問題，但是錯誤與您的不同。 – Doon
我確實做過捆綁舞，並且在那裏遇到了一些小問題。我還介紹了耙路軌：在您提到它之後更新。仍然沒有解決這個錯誤:( – kevinweaver
