我正在开发一个项目，将其更新到 Angular 6。更新后，我现在在尝试运行服务器端渲染构建时收到此错误
Module not found: Error: Can't resolve './dist/server/main.bundle'
我尝试去https://angular.io/guide/universal https://angular.io/guide/universal并将我的代码与 Angular Universal 中的 SSR 文件相匹配。这对我不起作用。
看来 dist 文件夹没有生成 /server 文件夹，而是创建 /browser。我不确定为什么。
这是我的 angular.json 文件

服务器.ts
// These are important and needed before anything else
import 'zone.js/dist/zone-node';
import 'reflect-metadata';
import { enableProdMode } from '@angular/core';
import * as express from 'express';
import { join } from 'path';
// 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');
// * NOTE :: leave this as require() since this file is built Dynamically from webpack
const { AppServerModuleNgFactory, LAZY_MODULE_MAP } = require('./dist/server/main.bundle');
// Express Engine
import { ngExpressEngine } from '@nguniversal/express-engine';
// Import module map for lazy loading
import { provideModuleMap } from '@nguniversal/module-map-ngfactory-loader';
app.engine('html', ngExpressEngine({
bootstrap: AppServerModuleNgFactory,
providers: [
provideModuleMap(LAZY_MODULE_MAP)
]
}));
app.set('view engine', 'html');
app.set('views', join(DIST_FOLDER, 'browser'));
// TODO: implement data requests securely
app.get('/api/*', (req, res) => {
res.status(404).send('data requests are not supported');
});
// 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('index', { req });
});
// Start up the Node server
app.listen(PORT, () => {
console.log(`Node server listening on http://localhost:${PORT}`);
});
一切都完全按照 Angular Universal 方向设置。
有人知道为什么我的构建脚本不会生成 /server 文件夹吗？
