升级到 Angular 12 和 Webpack

Question

我已经使用 .NET 框架将 Angular 6 项目升级到 Angular 12。我目前面临 2 个问题。

1)

我在 package.json 中指定构建命令为：

"prodbuild": "ng build --configuration production --aot=true --output-hashing none",
"build": "ng build --output-hashing none",

并且我能够使用 ng build --output-hashing none 进行编译。但是，我无法使用 Chorme 开发工具调试代码，源显示来自 Webpack 而不是项目的目录结构。我在 ts 文件中更改的代码未在开发工具中更新。我尝试过清除缓存、刷新页面，但都没有用。

我之前一直在用

ng build --watch

什么取代了它？这样在浏览器中更新代码和刷新非常方便。

这是我的 angular.json:

请指教！

ng build 现在默认使用生产配置编译。

尝试ng build --watch --configuration development或ng serve
