MIME类型（'text / html'）不是受支持的样式表MIME类型，并且启用了严格的MIME检查

Question

我在Heroku上的Angular 8应用程序中遇到了Deploy问题。错误：

Refused to apply style from 'https://capitu.herokuapp.com/styles.3ff695c00d717f2d2a11.css' because its MIME type ('text/html') is not a supported stylesheet MIME type, and strict MIME checking is enabled.

和

GET https://capitu.herokuapp.com/runtime-es2015.edb2fcf2778e7bf1d426.js net::ERR_ABORTED 404 (Not Found)

也可以在控制台上的链接上看到它： https://capitu.herokuapp.com/

我的文件package.json具有此配置

我的Node.js服务器具有配置：

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

const app = express();

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

app.get('/', (req,res) => {

res.render(__dirname + '/index.html')
});

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

有人会解决这个问题吗？感激
