我正在使用带有 ruby​​ 1.9.3 的 Rails 3.2.9（默认使用 RVM）。当我执行命令'rails console'/'rails c'时，从我的test_app的根目录中，显示以下错误。

rails console

是的，我得到了我的问题的答案。

只需在应用程序文件夹的根目录中打开文件“Gemfile”，然后将下面的行粘贴到那里。

gem 'execjs'

gem 'libv8'

gem 'therubyracer'

粘贴后，只需保存文件并在命令提示符下执行“捆绑更新”。

成功完成包更新后，您尝试运行“rails c”或“rails console”以获取 rails 控制台。有用！！

谢谢你。
