node.js - VSCode 调试控制台只显示 nodemon 消息

问题描述

我添加了启动配置来运行一个小应用程序，用于测试目的

    "version": "0.2.0",
    "configurations": [
        {
            "type": "node",
            "request": "launch",
            "name": "Launch Program",
            "skipFiles": [
                "<node_internals>/**"
            ],
            "runtimeExecutable": "nodemon",
            "restart": true,
            "program": "${workspaceFolder}\\express-qr-code.js"
        }
    ]

但是当我收到错误时，它不会在控制台中记录错误，并且只显示 nodemon 输出。例如：

[nodemon] 2.0.3
[nodemon] to restart at any time, enter `rs`
[nodemon] watching path(s): *.*
[nodemon] watching extensions: js,mjs,json
[nodemon] starting `node --inspect .\express-qr-code.js`
[nodemon] app crashed - waiting for file changes before starting...

因此，您可以看出它对调试非常适得其反。

这是我从终端启动同一个应用程序时得到的

PS C:\Projects\Testing\Node> nodemon .\express-qr-code.js
[nodemon] 2.0.3
[nodemon] to restart at any time, enter `rs`
[nodemon] watching path(s): *.*
[nodemon] watching extensions: js,mjs,json
[nodemon] starting `node .\express-qr-code.js`
events.js:200
      throw er; // Unhandled 'error' event
      ^

}

如何让调试控制台显示所有消息？

解决方案

似乎找不到启动 nodemon 进程并检查启动文件的方法。唯一的解决方案是让日志显示在终端窗口中，而调试日志显示在调试控制台中。repo 有一个自述文件，用于完成设置。您将在终端窗口中获​​得所有日志。只是没有调试控制台消息。那些将在调试控制台中
