“样式”：[...] 在 angular.json 中不起作用

Question

我一直在尝试在我的项目中实现 Angular 材料，并在styles.scss中导入了预建主题。 但这没有用。 所以我尝试将它添加到angular.json文件中，但似乎也没有成功。 然后我angular.json styles.scss在"styles":[] 有谁知道可能是什么问题？

我的angular.json文件

尝试使用这种格式：

"styles": [
          "./node_modules/@angular/material/prebuilt-themes/indigo-pink.css",
          "src/styles.scss"
         ],

也不要忘记使用ng serve重新启动应用程序以应用更改。
