Question

我有一个使用angular 7构建的可正常运行的网站，并且我正在尝试使用服务器端渲染构建它。运行webpack --config webpack.server.config.js --progress --colors成功，但是node dist/server产生以下错误：

/path/to/project/dist/server.js:225854
__WEBPACK_AMD_DEFINE_RESULT__ !== undefined && (module.exports = __WEBPACK_AMD_DEFINE_RESULT__));
else {}})(this,function(){"use strict";
function b(a,b){return"undefined"==typeof b?b={autoBom:!1}:"object"!=typeof b&&(console.warn("Depricated: Expected third argument to be a object"),b={autoBom:!b}),b.autoBom&&/^\s*(?:text\/\S*|application\/xml|\S*\/\S*\+xml)\s*;
.*charset\s*=\s*utf-8/i.test(a.type)?new Blob(["\uFEFF",a],{type:a.type}):a}function c(b,c,d){var e=new XMLHttpRequest;e.open("GET",b),e.responseType="blob",e.onload=function(){a(e.response,c,d)},e.onerror=function(){console.error("could not download file")},e.send()}function d(a){var b=new XMLHttpRequest;
return b.open("HEAD",a,!1),b.send(),200<=b.status&&299>=b.status}function e(a){try{a.dispatchEvent(new MouseEvent("click"))}catch(c){var b=document.createEvent("MouseEvents");
b.initMouseEvent("click",!0,!0,window,0,0,0,80,20,!1,!1,!1,!1,0,null),a.dispatchEvent(b)}}var f="object"=

ReferenceError: HTMLAnchorElement is not defined
    at Object.<anonymous> (/path/to/project/dist/server.js:225854:1182)

我不确定它是从哪里来的，并且似乎没有其他任何问题可以解决相同的问题。这是我制作的server.ts文件：

import 'zone.js/dist/zone-node';
import 'reflect-metadata';

import { renderModuleFactory } from '@angular/platform-server';
import { enableProdMode } from '@angular/core';

import * as express from 'express';
import { join } from 'path';
import { readFileSync } from 'fs';

// Faster server renders w/ Prod mode (dev mode never needed)
enableProdMode();

// Express server
const app = express();

const PORT = process.env.PORT || 4000;
const DIST_FOLDER = join(process.cwd(), 'dist');

// Our index.html we'll use as our template
const template = readFileSync(join(DIST_FOLDER, 'browser', 'index.html')).toString();

// Fix for window
const domino = require('domino');
const win = domino.createWindow(template);

global['window'] = win;
global['document'] = win.document;
global['navigator'] = win.navigator;
global['CSS'] = undefined;

// * NOTE :: leave this as require() since this file is built Dynamically from webpack
const { AppServerModuleNgFactory, LAZY_MODULE_MAP } = require('./dist/server/main');

const { provideModuleMap } = require('@nguniversal/module-map-ngfactory-loader');

app.engine('html', (_, options, callback) => {
  renderModuleFactory(AppServerModuleNgFactory, {
    // Our index.html
    document: template,
    url: options.req.url,
    // DI so that we can get lazy-loading to work differently (since we need it to just instantly render it)
    extraProviders: [
      provideModuleMap(LAZY_MODULE_MAP)
    ]
  }).then(html => {
    callback(null, html);
  });
});

app.set('view engine', 'html');
app.set('views', join(DIST_FOLDER, 'browser'));

// Server static files from /browser
app.get('*.*', express.static(join(DIST_FOLDER, 'browser')));

// All regular routes use the Universal engine
app.get('*', (req, res) => {
  res.render(join(DIST_FOLDER, 'browser', 'index.html'), { req });
});

// Start up the Node server
app.listen(PORT, () => {
  console.log(`Node server listening on http://localhost:${PORT}`);
});

这是webpack.server.config.js：

const path = require('path');
const webpack = require('webpack');

module.exports = {
  entry: {  server: './server.ts' },
  mode: 'none',
  resolve: { extensions: ['.js', '.ts'] },
  target: 'node',
  // this makes sure we include node_modules and other 3rd party libraries
  externals: [/(node_modules|main\..*\.js)/,'bufferutil', 'utf-8-validate'],
  output: {
    path: path.join(__dirname, 'dist'),
    filename: '[name].js'
  },
  module: {
    rules: [
      { test: /\.ts$/, loader: 'ts-loader' }
    ]
  },
  plugins: [
    // Temporary Fix for issue: https://github.com/angular/angular/issues/11580
    // for "WARNING Critical dependency: the request of a dependency is an expression"
    new webpack.ContextReplacementPlugin(
      /(.+)?angular(\\|\/)core(.+)?/,
      path.join(__dirname, 'src'), // location of your src
      {} // a map of your routes
    ),
    new webpack.ContextReplacementPlugin(
      /(.+)?express(\\|\/)(.+)?/,
      path.join(__dirname, 'src'),
      {}
    ),
    new webpack.IgnorePlugin( /uws/ )
  ]
}

运行常规客户端构建（例如npm start）没有问题。关于什么可能导致此问题的任何建议？还有其他有用的信息吗？预先感谢！
