vscode无法调试Express Webapp

Question

我正在尝试调试机器上的express（节点）应用程序，但是调试始终没有任何提示。

这种情况发生在我可以在另一台机器上调试的代码以及为了测试此问题而创建的“新”应用程序上。 我没有按照vscode网站（https://code.visualstudio.com/docs/nodejs/nodejs-debugging）上的说明进行操作。 运行时效果很好-只是无法调试。 行为取决于所有计算机的用户（管理员/非管理员）

有人知道吗？

我的环境设置是：

• 操作系统：Windows 10 Pro 1803版
• 节点版本：v10.13.0
• vscode版本：1.28.2

这是vscode的跟踪记录（请注意目标未打开警告）：

这是附加调试器后的vscode屏幕的片段。如您所见，调试器已附加，但是没有调试工具栏（并且断点处没有中断）：

Answer 1

您可以尝试通过转到 Debug-> Add Configuration

添加launch.json。

然后选择 Node.js附加到进程

{
  "version": "0.2.0",
  "configurations": [        
    {
        "type": "node",
        "request": "attach",
        "name": "Attach by Process ID",
        "processId": "${command:PickProcess}"
    },
    {            
        "name": "Attach",
        "type": "node",
        "request": "attach",
        "port": Your Port,
        "address": "localhost",
        "restart": false,
        "sourceMaps": false,
        "outDir": null,
        "localRoot": "${workspaceRoot}",
        "remoteRoot": null
    }
  ]
}

然后像往常一样运行服务器

> nodemon app.js

设置断点

然后按开始调试

调试器应该启动，您应该微笑：）
