感谢您抽出时间阅读我的问题。当我运行ng serve时，我的网站正常工作。当我运行ng build --prod时，也能正常工作。问题是，当我尝试在dist中呈现index.html时，我会遇到404错误。这些错误是我的主文件、样式文件和polyfill文件的404错误。我正在尝试构建一个后端，以便可以处理信用卡支付。任何帮助都将不胜感激——我已经连续几个小时碰壁了，但没有解决。以下是我的代码：
server.js
server.js
var express = require('express');
var app = express();
var server = require('http').Server(app);
var bodyParser = require('body-parser');
app.use(express.static(__dirname));
app.use(bodyParser.json());
app.use(bodyParser.urlencoded({extended: true}));
server.listen(2000, function(){
console.log('Listening on 2000..')
});
console.log(__dirname);
app.get('/', (req, res) => {
res.sendFile(__dirname + '/dist/culture/index.html');
});

简而言之，localhost返回200代码，这意味着它连接到了正确的位置。问题是一旦连接上了，它找不到任何文件。我做错了什么？谢谢。
