我已经遵循了提供的相同文档，并且能够将应用程序部署到Azure应用程序服务，没有任何问题。

在package.json中，将start更改为

"scripts": {
"start": "node ./bin/www"
},

如给定文档中所述，设置SCM_DO_BUILD_DURING_DEPLOYMENT命令后，Azure应用服务中将生成web.config。但我在您的文件夹结构中没有看到生成的web.config文件。

我的package.json

{
    "name": "myexpressapp",
    "version": "0.0.0",
    "private": true,
    "scripts": {
        "start": "node ./bin/www"

    "express": "~4.16.1",
    "http-errors": "~1.6.3",
    "morgan": "~1.9.1"
    }
}

我的索引.js

var  express = require('express');
var  router = express.Router();
/* GET home page. */
router.get('/', function(req, res, next) {
res.render('index', { title:  'Express' });
});
module.exports = router;

从VSCode重新部署应用程序后，请确保SCM_DO_BUILD_DURING_DEPLOYMENT设置在Configuration =〉Application Settings中可用。
