无法使用 Angular 13 在 VS Code 中命中断点

Question

下面是我的launch.js

{
    // Use IntelliSense to learn about possible attributes.
    // Hover to view descriptions of existing attributes.
    // For more information, visit: https://go.microsoft.com/fwlink/?linkid=830387
    "version": "0.2.0",
    "configurations": [
        {
            "type": "pwa-chrome",
            "request": "launch",
            "name": "Launch Chrome against localhost",
            "url": "http://localhost:4200",
            "webRoot": "${workspaceFolder}"
        }
    ]
}

在launch.js，我试过把webRoot改成"webRoot": "${workspaceFolder}/src"，没有影响。

我的应用程序使用ng serve 启动并运行，但是当我点击F5 启动调试模式时，没有一个断点被命中，它们都是unbound/greyed out。

下面是我的angular.js，以防万一有人需要。

还有什么可以让它发挥作用？

谢谢。

我遇到了同样的问题，从 Angular 11 更新到 13，然后我找到了一些帮助，并在我的项目中执行了以下步骤：

1.- 编辑 : angular.json 文件。

将以下行（sourceMap 和优化）添加到相应的部分或环境中，例如：

"configurations": {
    .......
    .......
    .......
   "dev" : {
    "sourceMap": true,
    "optimization": false,
    ..... // More code
   },
   "devlocal" : {
    "sourceMap": true,
    "optimization": false,
    ..... // More code
   }


}

2.- 重新启动您的 Angular 应用程序。 3.- 将断点放在组件中。 4.- 使用 chrome 或 Visual Studio 代码调试您的应用程序。

就是这样！！！

它适用于我。 :)
