SassC::SyntaxError：错误：“}”后的 CSS 无效：答案

【问题标题】：SassC::SyntaxError: Error: Invalid CSS after "}":SassC::SyntaxError：错误：“}”后的 CSS 无效：
【发布时间】：2019-01-20 17:33:18
【问题描述】：

我正在尝试预编译 + 缩小我的 js 和 css 资产。

如果我跑步：rake assets:precompile

然后它运行良好，但没有缩小。

如果我运行：SECRET_KEY_BASE=rake secretRAILS_ENV=production rake assets:precompile

然后它返回错误消息并且不编译：SassC::SyntaxError: Error: Invalid CSS after "}": expected 1 selector or at-rule, was '!function(){if("und' on line 17881 of stdin

我尝试过更新各种 gem，更改一些 CSS，将 @import 添加到 application.scss 等，但似乎都没有工作。

这是完整的错误信息：

rake aborted!
SassC::SyntaxError: Error: Invalid CSS after "}": expected 1 selector or at-rule, was '!function(){if("und'
        on line 17881 of stdin
>> }

   -^

我错过了什么让它预编译和缩小我的 js 和 css？

【问题讨论】：

显示代码，它抱怨 CSS 语法错误，但错误上显示的行是 Javascript

标签： ruby-on-rails

【解决方案1】：

对于任何搜索此内容的人，最后我只是删除了我的 CSS 和 JS 中包含有问题的行 (!function(){if() 中的两个实例。

仍然不确定它们为什么会导致此错误，但由于它们并没有被积极使用（与我目前不使用的视频相关），我很高兴在没有它们的情况下删除和编译。
