当我运行时ng build --prod出现此错误。它可以毫无错误地服务，但不能构建。我接力与那个绑在一起
ERROR in Module build failed (from ./node_modules/@angular-devkit/build-angular/node_modules/mini-css-extract-plugin/dist/loader.js):

如何解决此错误？
https://github.com/webpack-contrib/mini-css-extract-plugin/issues/186 的讨论包括一条语句，即当任何组件具有数组值长度大于 1 的 styleUrls 属性时，会发生此错误。
我在一个应用程序中验证了这一点，在该应用程序中，将此属性的值减小到长度为 1 的数组会使错误消失。
在我的情况下，某些 CSS 无法正常工作，这就是为什么当我一一检查时找到这个 error.it。 因为此错误隐藏了其他错误。
我有这个错误，因为我错误地将"是angular.json文件中的样式列表。我想添加 css 文件并开始输入，但我以另一种方式制作，我把这个"留在那里。
