找不到模块'../dist/ngfactory/src/app/app.server.module.ngf actory'。 角度cli

Question

I wanted to make my angular app seo friendly so I searched google and found several solutions Make your Angular App SEO-Friendly (Angular 4 + Universal) I follow the instructions however when I run the project with npm run start the following error occurred:

src/server.ts(5,42): error TS2307: Cannot find module '../dist/ngfactory/src/app/app.server.module.ngf
actory'.

I search entire day looking for solution I read this issue [AOT] @ngtools/webpack throws "Cannot find module './ngfactory/app/app.module.ngfactory'" however my problem didn't solve my problem all of my packages are the latest version and this is my build commmand inside package.json

"prestart": "ng build --prod && ./node_modules/.bin/ngc",
"start": "ts-node src/server.ts",

here is server.ts file:

import 'reflect-metadata';
import 'zone.js/dist/zone-node';
import { platformServer, renderModuleFactory } from '@angular/platform-server'
import { enableProdMode } from '@angular/core'
import { AppServerModuleNgFactory } from '../dist/ngfactory/src/app/app.server.module.ngfactory'
import * as express from 'express';
import { readFileSync } from 'fs';
import { join } from 'path';

const PORT = 4200;

enableProdMode();

const app = express();

let template = readFileSync(join(__dirname, '..', 'dist', 'index.html')).toString();

app.engine('html', (_, options, callback) => {
  const opts = { document: template, url: options.req.url };

  renderModuleFactory(AppServerModuleNgFactory, opts)
    .then(html => callback(null, html));
});

app.set('view engine', 'html');
app.set('views', 'src')

app.get('*.*', express.static(join(__dirname, '..', 'dist')));

app.get('*', (req, res) => {
  res.render('index', { req });
});

app.listen(PORT, () => {
  console.log(`listening on http://localhost:${PORT}!`);
});

i don't know if it will help or not but you can Try To Put (./) in "start" : "th-node ./",

"prestart": "ng build --prod && ./node_modules/.bin/ngc",
"start": "ts-node ./src/server.ts"
