无法通过在 Visual Studio Code 中为 Angular 8 项目启动 Chrome 调试器来工作

Question

将 Angular 升级到版本 8 后，我现在无法在 Visual Studio Code 中运行 Chrome 调试器。

我没有改变我的launch.json，它类似于以下内容：

{
  "type": "chrome",
  "request": "launch",
  "name": "Launch Chrome (https)",
  "url": "https://myhost.domain.com:4200",
  "webRoot": "${workspaceFolder}"
},

我通过以下命令启动 Angular 应用程序

ng serve --host myhost.domain.com --ssl --disableHostCheck

这在升级之前已经工作了很长时间。我能够在 Angular 中启动 Chrome 并调试不同的组件。现在它所做的只是声明“未验证的断点”

我尝试了以下方法：

• 将 webRoot 文件夹位置更改为不同的可能位置。当我提供应用程序时，我确实注意到输出中有一条新消息。( https://myhost.domain.com:4200/webpack-dev-server/ ? ?wds?: webpack 输出来自 / ? ?wds?: 404s 将回退到 //index.html)

• 卸载和重新安装 Visual Studio Code 扩展

• 添加 SourceMap：true
• 使用 ng new test-project 创建一个全新的 Angular 项目并尝试调试这个项目，它也做同样的事情。

这是我的 package.json 的样子：

{
  "name": "my-application",
  "version": "0.7.2",
  "scripts": {
    "ng": "ng",
    "start": "ng serve",

Angular 8的调试launch.json和tasks.json配置已更改（最近于 2019 年 7 月更新）

您可以在 VSCode 文档站点上找到最流行的调试方法的链接和详细信息。

Angular 的特定版本在 vscode-recipies GitHub 页面上：https : //github.com/Microsoft/vscode-recipes/tree/master/Angular-CLI

在此处发布完整配置时，它们经常更改以使其值得，因此只需放入链接
