无法在VS代码中调试角度测试：未验证的断点

Question

我有CLI生成的非常标准的angular 7项目。我只更改了.tsconfig中的baseUrl：

{
  "compileOnSave": false,
  "compilerOptions": {
    "baseUrl": "./src",
    "outDir": "./dist/out-tsc",
    "sourceMap": true,
    "declaration": false,
    "downlevelIteration": true,
    "module": "es2015",
    "moduleResolution": "node",
    "emitDecoratorMetadata": true,
    "experimentalDecorators": true,
    "importHelpers": true,
    "target": "es5",
    "typeRoots": [
      "node_modules/@types"
    ],
    "lib": [
      "es2018",
      "dom"
    ]
  }
}

我有这个laung.json：

{
  "version": "0.2.0",
  "configurations": [
    {
      "type": "chrome",
      "request": "launch",
      "name": "Launch Chrome against localhost",
      "url": "http://localhost:4200",
      "webRoot": "${workspaceFolder}"
    },
    {
      "name": "ng test",
      "type": "chrome",
      "request": "launch",
      "url": "http://localhost:9876/debug.html",
      "webRoot": "${workspaceFolder}",
      "sourceMaps": true,
      "sourceMapPathOverrides": {
        "/./*": "${webRoot}/*",
        "/src/*": "${webRoot}/*",
        "/*": "*",
        "/./~/*": "${webRoot}/node_modules/*"
      }
    }
  ]
}

对应用程序进行压缩即可。没有调试测试。它说：断点未经验证，它没有命中。
