Html 赫罗库没有'；无法在CSS中获得本地更改

我有个奇怪的问题。 我的heroku应用程序没有从CSS获取本地更改。 但它从.html.erb文件中获取所有更改。 例如：如果我在custom.css中编写body

{background:black！important}

，则背景仅在本地为黑色，在heroku应用程序中为正常。 但是如果我在.html.erb文件中写入

body style=“background:black}

，我将得到更改。 我该怎么办？ 你需要我的gem、CSS或SCSS文件吗

顺便说一句，我删除了gemfile中的

gem'sass-rails'，“~>5.0”

，它开始工作。但这很奇怪，所以我很想知道问题出在哪里。

运行

rails\u ENV=production bundle exec-rake-assets:precompile

在将你的应用程序上传到Heroku之前预编译你的资产。

你能分享你的

production.r吗b

、

application.css

和

gem

文件？@SzilardMagyar是的，5秒=）您是否预编译了您的资产？@SzilardMagyar请参阅更新）@MarcK。我以为资产是自动预编译的。我该怎么做？
