Heroku中的节点应用程序：模块构建失败：错误：发现意外的“空间”

Question

我有一个节点应用程序已经在Heroku上运行了一年，但是最近的更新现在在构建时崩溃了。我以前从未见过此错误，也找不到任何帮助。

这是错误日志：

       yarn run v1.12.3
       $ react-scripts build
       Creating an optimized production build...
       Failed to compile.

       ./src/components/Admin_Navigation/navigation.css
       Module build failed: Error: Unexpected "space" found.

我尝试了以下操作：

1. 更新纱线锁
2. 更新package.JSON
3. 更新的纱线和节点版本

您的任何想法都会受到赞赏。谢谢

更新：这是由CSS中不必要的空格引起的。您可以手动在CSS上查找该空间，或者不那么理想的解决方案是将Node回滚到语法不那么严格的版本。
