我使用Angular CLI创建了一个Angular 4 hello world应用程序,我想尝试使用AOT / WEBPACK构建的生产版本,但我无法使其工作。我按照angular.io网站(https://angular.io/docs/ts/latest/cookbook/aot-compiler.html)中的步骤进行操作。当我构建时,会出现引导错误。

当我构建时,我遇到错误
ng build --prod
Tried to find bootstrap code, but could not. Specify either statically analyzable bootstrap code or pass in an entryModule to the plugins options.

请运行npm -g install @ angular / cli
然后创建生产构建
它可能是角度cli旧版本问题
如果你仍然发现问题,那么将下面的代码放在你的main.js
中import { WfaNg2Module } from './app';
并更改
platformBrowser().bootstrapModuleFactory(AppModuleNgFactory);
到
document.addEventListener('DOMContentLoaded', function () {
platformBrowserDynamic().bootstrapModule(WfaNg2Module, []);
}, false);
如果没有帮助,请告诉我

您不必再使用module:module.id了。它适用于先前的Angular 2版本。
参见 - &gt; https://angular.io/docs/ts/latest/cookbook/aot-compiler.html
组件相对模板网址
AOT编译器要求外部模板和CSS文件的@Component URLS是组件相关的。这意味着@ Component.templateUrl的值是相对于组件类文件的URL值。例如,'app.component.html'URL表示模板文件是其配套app.component.ts文件的兄弟。
虽然JIT应用程序URL更灵活,但为了与AOT编译兼容,请坚持使用与组件相关的URL。

import { platformBrowserDynamic } from '@angular/platform-browser-dynamic';
import { enableProdMode } from '@angular/core';
import { environment } from './environments/environment';
import { AppModuleNgFactory } from '../aot/src/app/app.module.ngfactory';
import { BSystemService } from './bGlobal/BSystemService';
let bSystemService: BSystemService = BSystemService.getInstance();
if (environment.production) {
enableProdMode();
}
if (bSystemService.deviceType == 'MOBILE') {
document.addEventListener('deviceready', function() {
bootstrapNow();
});
} else {
bootstrapNow();
}
function bootstrapNow() {
platformBrowserDynamic().bootstrapModule(AppModuleNgFactory);
