Question

我试图在Heroku上托管Anglar Web应用程序，但是当我尝试建立我的专案，上面说建立成功，当我进入网路时网址。它显示（应用程序错误）页面。
让我清楚一点，我正在使用Github存储库进行自动部署。
我的package.json是附加服务器。
我也正在使用这个tutorial寻求帮助。

Server.js文件

//Install express server
const express = require('express');
const path = require('path');

const app = express();

// Serve only the static files form the dist directory
app.use(express.static(__dirname + '/dist/WebApp'));

app.get('/*', function(req,res) {

res.sendFile(path.join(__dirname+'/dist/WebApp/index.html'));
});

// Start the app by listening on the default Heroku port
// app.listen(process.env.PORT || 8080);
app.listen(process.env.PORT || 5000);
