Question

我正在尝试通过以下方法在Heroku服务器上部署angular应用程序。 https://medium.com/@hellotunmbi/how-to-deploy-angular-application-to-heroku-1d56e09c5147

如果有人对此有任何想法，请在我试图找出此错误的根源时帮助我。在此先感谢

我将-prod更改为--prod，这帮助我成功地部署了该应用程序，但是，在打开该应用程序时，它给了我“” not found error“”，并且控制台错误是无法加载资源：服务器响应状态为404（未找到）。

这是应用程序的链接 https://recipebook-angularapp.herokuapp.com/

此应用程序可以在我的本地服务器上完美运行。

这是我的package.json

  },
  "engines": {

    "npm": "6.5.0"
  }
}

和server.js

//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('./dist/recipe-book'));

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

res.sendFile(path.join(__dirname,'/dist/recipe-book/index.html'));
});

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

在Heroku服务器上部署angular应用时出错
