这是 application.html.erb 文件中的一行 <%= stylesheet_link_tag yield(:css), 媒体: "all", "data-turbolinks-track"=> true %> 并且 css 加载每个不同页面所需的文件名。
本地服务器的结果非常好，在 Heroku 中，该命令提供的 css 抛出“您要查找的页面不存在。
您可能输错了地址，或者页面可能已移动。”
以防万一我尝试预编译 Assets 。感谢您提前回复，我将继续显示日志:

最佳答案
可能是 categories.css 不在编译列表中。你可以在 config/application.rb 中尝试这样的事情:
config.assets.precompile += ['categories.css']
替换任何实际文件名(可能是 categories.sass)。
关于css - Heroku 找不到带有 stylesheet_tag 命令的 css(在本地工作)，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/17904702/
