'rails console'命令在Rails 3.2.9中拋出錯誤

我正在使用Rails 3.2.9和ruby 1.9.3（使用RVM進行默認設置）。從我的test_app的根目錄執行命令'rails console'/'rails c'時，顯示以下錯誤。'rails console'命令在Rails 3.2.9中拋出錯誤

是的，我有我的問題的答案。

只需打開應用程序文件夾根目錄下的文件'Gemfile'，然後將下面的行粘貼到那裏。

gem 'execjs' 

gem 'libv8' 

gem 'therubyracer'

粘貼後，只要保存文件並執行命令提示符「捆綁更新」。

成功完成軟件包更新後，您嘗試運行'rails c'或'rails console'來獲取rails控制檯。有用！！

謝謝。

嘗試安裝

gem 'therubyracer'

不行！我安裝了gem'therubyracer'和gem'execjs'並進行了捆綁更新。它不工作，同樣的錯誤再次顯示。 –

嗨@Rajesh，好像你在這裏使用rvm，那麼你確定你將寶石捆綁在正確的rvm包中嗎？ – sameera207

我不明白。你能澄清這個問題嗎？ –

安裝如下因素都：

gem 'execjs' 
gem 'therubyracer'

嘗試運行'捆綁安裝'而不是'捆綁更新' – VenkatK

我已經這樣做了，並且我在上面的評論中提到過。 –
