我的rails应用程序运行正常，直到我在Windows cmd提示符下键入以下命令行：“bundle exec rake assets：clean”。在我这样做并再次进入rails服务器后，主页上弹出了以下错误。
如何摆脱下面提到的错误或者如何解决“捆绑exec rake资产：干净”导致此错误？
ExecJS::RuntimeError in Aaa_core#index
Showing C:/Sites/AAA_Website_new/app/views/layouts/application.html.erb where line #7 raised:

以下是应用程序跟踪： app / views / layouts / application.html.erb：7：在`_app_views_layouts_application_html_erb__51027894_38988708'
我已经尝试过“捆绑安装”，这是我的宝石列表：
