ruby-on-rails – 如何修复模板错误“CoffeeScript未定义”

我试图让我的项目的视图显示出来.但我得到这个错误：

ActionView::Template::Error (ReferenceError: CoffeeScript is not defined):
4:     <title>Myapp</title>
5:     <%= csrf_Meta_tags %>
6:
7:     <%= stylesheet_link_tag    'application',media: 'all','data-turbolinks-track': 'reload' %>
8:     <%= javascript_include_tag 'application','data-turbolinks-track': 'reload' %>
9:   </head>

10：

当我删除第7-8行然后它工作,但我没有CSS或JavaScript.

一周前我没有收到这个错误.我不确定原因是什么.我试过切换Rails版本.我已经尝试卸载Postgres并重新设置它,但它似乎不是问题.
我有Rails 5.0.0.1和“Ruby 2.3.3p222(2016-11-21修订版56859)[x86_64-darwin16]”.我也在使用Mac OS Sierra.

我可以将“应用程序”更改为“默认”并且它可以工作,但我不明白为什么它在一周前工作,而不是现在.

我也有我的视图和控制器设置,这就是为什么它删除第7-8行时的原因.

这是我的宝石文件：

解决方法

最近更新的coffe-script-source gem 1.12.1存在问题.问题是此版本中的源文件为空.已经有一个 open issue,它应该很快修复.

现在您可以将它添加到您的GemFile中

gem 'coffee-script-source','= 1.11.1'

并运行bundle update coffee-script-source直到它被修复.
