我的 rails 应用程序运行良好，直到我在 Windows cmd 提示符中键入以下命令行：“bundle exec rake assets:clean”。在我这样做并再次进入rails服务器后，主页上弹出以下错误。
如何摆脱下面提到的错误，或者如何扭转导致此错误的任何“bundle exec rake assets:clean”？
ExecJS::RuntimeError in Aaa_core#index
Showing C:/Sites/AAA_Website_new/app/views/layouts/application.html.erb where line #7 raised:
(in C:/Sites/AAA_Website_new/app/assets/javascripts/aaa_core.js.coffee)
Extracted source (around line #7):

7: <%= javascript_include_tag "application" %>
8: <%= csrf_meta_tags %>

这是应用程序跟踪：app/views/layouts/application.html.erb:7:in `_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：
