Question

我从一个新项目开始，团队正在使用Webpack构建其角度应用程序。该Webpack配置根本不支持源映射。现在我们升级到了Angular 8，于是，我们决定使用Angular-CLI。

CLI应该开箱即用地支持Source Maps，但是不知何故它只加载所有组件的样式

但是只要我直接从main.js中检查源映射，就可以找到所有映射的代码。

是否有可能我们错过了某些配置，或者某些重要软件包取消了源地图？对于一个新的cli项目，sourcemaps运行良好

对于那些有相同问题的人。我可以按照以下步骤进行修复

创建一个新的ng CLI项目，
将所有资产和代码移至新项目
使新项目运行
用新创建的项目替换存储库中的角度文件夹

Angular CLI生成用于打字稿的源地图，但浏览器仅加载样式源地图
