Angular应用正确编译,但未加载

我正在使用Angular 6构建应用程序,现在我想使用ExpressJS为其提供服务。

为此,我继续使用ng serve --prod编译应用程序,但是由于正在控制台中获取SyntaxError: expected expression, got '<',因此应用程序未加载。

我以为我的应用程序可能出了点问题,但是在ng serve上运行正常,因此我在ng serve --prod上进行了尝试,一切仍然正常运行。

然后,我决定仅尝试ng build(不尝试--prod),并遇到相同的错误。

在GitHub问题中,我找到了一些相关的东西,但特定于某些软件包和较旧版本的angular。

如果相关,这是我的package.json:

{
  "name": "mt",
  "version": "0.0.0",
  "scripts": {
    "ng": "ng",
    "start": "ng serve",
    "build": "ng build",
    "test": "ng test",
    "lint": "ng lint",
    "e2e": "ng e2e"
  },
  "private": true,
  "dependencies": {
    "@angular/animations": "^6.1.0",
    "@angular/cdk": "^6.4.7",
    "@angular/common": "^6.1.0",
    "@angular/compiler": "^6.1.0",
    "@angular/core": "^6.1.0",
    "@angular/forms": "^6.1.0",
    "@angular/http": "^6.1.0",
    "@angular/material": "^6.4.7",
    "@angular/platform-browser": "^6.1.0",
    "@angular/platform-browser-dynamic": "^6.1.0",
    "@angular/router": "^6.1.0",
    "core-js": "^2.5.4",
    "d3": "^5.7.0",
    "dateformat": "^3.0.3",
    "rxjs": "~6.2.0",
    "xlsx": "^0.14.1"
  },
  "devDependencies": {
    "@angular-devkit/build-angular": "~0.8.0",
    "@angular/cli": "~6.2.1",
    "@angular/compiler-cli": "^6.1.0",
    "@angular/language-service": "^6.1.0",
    "@types/jasmine": "~2.8.8",
    "@types/jasminewd2": "~2.0.3",
    "@types/node": "~8.9.4",
    "codelyzer": "~4.3.0",
    "jasmine-core": "~2.99.1",
    "jasmine-spec-reporter": "~4.2.1",
    "karma": "~3.0.0",
    "karma-chrome-launcher": "~2.2.0",
    "karma-coverage-istanbul-reporter": "~2.0.1",
    "karma-jasmine": "~1.1.2",
    "karma-jasmine-html-reporter": "^0.2.2",
    "protractor": "~5.4.0",
    "ts-node": "~7.0.0",
    "tslint": "~5.11.0",
    "typescript": "~2.9.2"
  }
}

我想问题不在于代码本身,因为应用程序在使用ng serve命令(不管是否带有--prod标志的情况下都可以正常工作)。

关于如何解决此问题的任何想法?

编辑:这是我为该应用服务的快速文件

const html = __dirname + '/dist/';
const port = 4200;
// Express
const bodyParser = require('body-parser');
const compression = require('compression');
const express = require('express');
var app = express();
app
    .use(compression())
    .use(bodyParser.json())
    // Static content
    .use(express.static(html))
    // Start server
    .listen(port, function () {
        console.log('Port: ' + port);
        console.log('Html: ' + html);
    });
app.get('*', function(req, res) {
  res.sendfile('./dist/mtloops-web-app/index.html');
});
