我有一个简单的 Angular 6 应用程序，我已部署到 heroku，但是当我运行时，
heroku logs
我收到以下错误

这是我的 procfile
worker: ng serve
这是我的结构

请注意，在我的本地计算机中，当我部署到 heroku 时，一切正常，我收到该错误，
Note its just a normal angular landing page without rest api
问题
我的代码有什么问题吗？
最佳答案
您需要安装服务器才能运行您的应用程序 在本地，我们从终端运行 ngserve 以在本地浏览器上运行我们的应用程序。但我们需要设置一个 Express 服务器来运行我们的生产就绪应用程序(从创建的 dist 文件夹中)，以确保轻量级和快速加载。
通过运行安装 Express 服务器:
npm install express path --save
在应用程序的根目录中创建一个 server.js 文件并粘贴以下代码。
//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'));
app.get('/*', function(req,res) {
res.sendFile(path.join(__dirname+'/dist/index.html'));
});
// Start the app by listening on the default Heroku port
app.listen(process.env.PORT || 8080);
更改启动命令 在package.json中，将“start”命令更改为node server.js，使其变为:
"start": "node server.js"
这是完整的 package.json 的样子。根据您的应用程序特定的软件包，您的软件包可能包含更多内容。
现在你的 package,json 应该是这样的
