Question

我已经使用link中的配方将Visual Studio代码配置为调试nodejs，chrome（vuejs）应用程序。但是，当我在Visual Studio代码中调试“ Meteor All”错误时，出现“无法执行调试脚本”错误。如果在服务器端代码中添加断点，则会看到“设置了断点但尚未绑定”。但是，我可以正确调试客户端代码。我想念什么？

Visual Studio代码中的Launch.json：

{
    "version": "0.2.0",
    "configurations": [
        {
            "type": "chrome",
            "request": "launch",
            "name": "Meteor: Chrome",
            "url": "http://localhost:3000",
            "webRoot": "${workspaceFolder}",
            "outputCapture": "std"
        },
        {
            "type": "node",
            "request": "launch",
            "name": "Meteor: Node",
            "runtimeExecutable": "npm",
            "runtimeArgs": ["run", "debug"],
            "outputCapture": "std",
            "port": 9229,
            "timeout": 30000
        }
    ],
    "compounds": [
        {
            "name": "Meteor: All",
            "configurations": ["Meteor: Node", "Meteor: Chrome"]
        }
    ]
}

登录Visual Studio代码：

C:\Program Files\nodejs\npm.cmd run debug 

> vue-meteor-demo@ debug c:\temp\vuemeteor2
> meteor run meteor --settings settings.json --inspect-brk=9229

Answer 1

我只使用--inspect，它工作正常。

我没有成功用--inspect-brk=9229指定端口

--inspect仍使用端口9229

您的服务器配置应如下所示：

{
  "type": "node",
  "request": "attach",
  "name": "server",
  "restart": true,
  "port": 9229
},

restart选项在您编辑代码时非常有用，因为它可以在服务器重启（通过重新连接）后继续存在

Answer 2

如果调试器无法通过调试器所附加的节点进程“到达”断点文件，则似乎显示此消息。

该错误消息在VS Code文档中没有很好地涵盖，因此很难找出导致该错误的原因。

我通过将文件添加到项目中并在其中放置一个断点来进行测试，但没有include / require在任何地方添加它。当您运行调试器（在另一个文件上）时，刚刚添加的断点将被“设置但尚未绑定”。相反，如果您include / require新文件，则断点将是正常的（即使您的测试从未达到断点所在的行）。

就我而言，我继承了一个代码库，发现如果您的脚本生成子进程（例如通过child_process.execFile），则调试器将不会跟踪子进程中的代码。而是将断点显示为“已设置断点但尚未绑定”。

调试node.js时出现“断点设置但尚未绑定”错误
