angular - VSCode Angular 5 Chrome 调试器问题 - 匹配空白？ - 和霍尔特

Question

其中一项更新突然停止工作后。我目前正在通过 Chrome 开发者工具进行调试。

ng serve works well and the app is running perfectly.

但是，我想再次使用 VSCode 进行调试..尝试了导致上述相同问题的几种配置。2.

{
"version": "0.2.0",
"configurations": [

  {
    "name": "ng serve",
    "type": "chrome",
    "request": "launch",
    "url": "http://localhost:4200/#",
    "webRoot": "${workspaceFolder}",
    "sourceMapPathOverrides": {
      "webpack:/./*": "${webRoot}/*",
      "webpack:/src/*": "${webRoot}/src/*",
      "webpack:/*": "*",
      "webpack:/./~/*": "${webRoot}/node_modules/*"
    }
  },
  {
    "name": "ng test",
    "type": "chrome",
    "request": "launch",
    "url": "http://localhost:9876/debug.html",
    "webRoot": "${workspaceFolder}"
  },
  {
    "name": "ng e2e",
    "type": "node",
    "request": "launch",
    "program": "${workspaceFolder}/node_modules/protractor/bin/protractor",
    "protocol": "inspector",
    "args": ["${workspaceFolder}/protractor.conf.js"]
  }
]

    }
  ]
}

禁用所有扩展，除了Chrome 调试器Visual Studio 团队服务

4200端口未被使用

netstat -a -n -o

我应该如何更改launch.json并通过VSCode恢复调试能力？

Answer 1

当端口 9222 开始使用时会发生此问题，因为此端口是 Debug模式的默认端口，因此只需使用另一个任意数字端口作为启动类型，就像我的 launch.json 文件一样

启动.json

{
    // 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": "chrome",
        "request": "launch",
        "name": "Launch Chrome",
        "url": "http://localhost:4200",
        "webRoot": "${workspaceFolder}",
        "port": 4040
        },
        {
          "type": "chrome",
          "request": "attach",
          "name": "Attach to Angular",
          "port": 9222,
           "webRoot": "${workspaceFolder}"
        }
    ]
}

until the time of writing this answer this consider a bug and will be fixed in future releases.
