基本 Node.js 项目的“属性‘程序’不存在”

我创建了简单的node.js应用程序（源代码来自这里https://azure.microsoft.com/en-us/blog/visual-studio-code-and-azure-app-service-a-perfect-fit/ https://azure.microsoft.com/en-us/blog/visual-studio-code-and-azure-app-service-a-perfect-fit/)

var http = require('http');
http.createServer(function (req, res) {
    console.log('Got request for ' + req.url);
    res.writeHead(200, {'Content-Type': 'text/html'});
    res.end('<h1>Hello Code and Azure Web Apps!</h1>');
}).listen(process.env.PORT);

然后点击VSCode生成的launch.json：

{
    "version": "0.2.0",
    "configurations": [
        {
            "name": "Launch",
            "type": "node",
            "request": "launch",
            "program": "${workspaceRoot}/app.js",
            "stopOnEntry": false,
            "args": [],
            "cwd": "${workspaceRoot}",
            "preLaunchTask": null,
            "runtimeExecutable": null,
            "runtimeArgs": [
                "--nolazy"
            ],
            "env": {
                "NODE_ENV": "development"
            },
            "externalConsole": false,
            "sourceMaps": false,
            "outDir": null
        },
        {
            "name": "Attach",
            "type": "node",
            "request": "attach",
            "port": 5858,
            "address": "localhost",
            "restart": false,
            "sourceMaps": false,
            "outDir": null,
            "localRoot": "${workspaceRoot}",
            "remoteRoot": null
        }
    ]
}

当启动时我仍然看到：

属性“程序”不存在。

有人可以帮忙出什么问题吗？

我相信你需要${workspaceRoot}/server.js, not ${workspaceRoot}/app.js for program。您使用的代码没有 app.js，这就是那个（措辞不佳的）错误告诉您的内容。
