[英]Why rails isn't displaying a web page
问题描述
每次启动Rails应用程序时，服务器都会显示一条错误消息。 例如（从命令行）：

尝试删除javascript_include_tag（标为虚线的行），然后查看页面是否加载。 如果页面确实加载，则关于javascript的资产文件可能有问题。

解决的第一种方法。 将以下行添加到文件application.js ：
//= require turbolinks
第二种解决方法。 在Gemfile为Gemfile gem 'coffee-script-source'设置版本1.8.0 ：
gem 'coffee-script-source', '1.8.0'
