从 css 到 scss 的 Angular-cli - Angular-cli from css to scss

问题：

I've read the documentation , which says that if I want to use scss I have to run the following command:我已经阅读了文档，它说如果我想使用scss我必须运行以下命令：

ng set defaults.styleExt scss

But when I do that and make that file, I still receive this error in my console:但是当我这样做并制作该文件时，我仍然在控制台中收到此错误：

styles.bundle.js:33Uncaught Error: Module build failed: Error: ENOENT: no such file or directory, open '/Users/Egen/Code/angular/src/styles.css'(…)
