我的 server.js：

const express = require('express');
const app = express();
const path = require('path');

app.use(express.static(__dirname + '/dist'));
app.listen(process.env.PORT || 8080);

//PATH LOCATION STARTEGY

app.get('/*', function(req,res){
  const fullPath = path.join(__dirname + '/dist/index.html');
  console.log(" Fetching from.." + fullPath);
    res.sendFile(fullPath);
})

console.log('Server started running..');

//Changed to run on Heroku

得到答案：

在 server.js 中，我必须将路径从 /dist 更改为 /dist/music-app 并且 从/dist/index.html 到/dist/music-app/index.html。

其中，music-app 是我的 package.json 文件中的名称属性 ["name": "music-app"]。
