找不到模块"./app/server.app.module.ngfactory"

Question

我在构建Angular aot时遇到以下错误：

找不到模块"/app/server.app.module.nfactory'

你能帮我确定可能出了什么问题吗？

main.server.aot.ts，其中包含以下内容：

import 'zone.js/dist/zone-node';
import 'reflect-metadata';
import 'rxjs/Rx';
import * as express from 'express';
import { ngExpressEngine } from '@nguniversal/express-engine';
import { enableProdMode } from '@angular/core';
import { ServerAppModuleNgFactory } from './ngfactory/app/server-app.module.ngfactory';
enableProdMode();
const app = express();
app.engine('html', ngExpressEngine({
bootstrap: ServerAppModuleNgFactory
}));
require('./main.server.shared').confApp(app);

这是tsconfig.server.aot

{
"extends": "./tsconfig.server.json",
"angularCompilerOptions": {
"genDir": "ngfactory",
"entryModule": "./app/server-app.module#ServerAppModule"
},
"include": [
"main.server.aot.ts"
]
}

由于您无法共享代码，建议您按照这里提到的步骤操作。查看配置中的差异。

少数建议：

1. No need of "genDir": "ngfactory" . Remove it from tsconfig.server.json
2. Lazy import :  const { AppServerModuleNgFactory, LAZY_MODULE_MAP } = require('./dist/server/main.bundle');
3. Server.ts -
// These are important and needed before anything else
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();
// * NOTE :: leave this as require() since this file is built Dynamically from webpack
const { AppServerModuleNgFactory, LAZY_MODULE_MAP } = require('./dist/server/main.bundle');
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}`);
