Angular2,AoT编译:无法确定组件AppComponent的模块

标签: angular angular2-aot angular2-providers

摘要:我正在尝试将Angular2 AoT用于我的Angular2应用程序,但由于我有静态提供程序将一些值从服务器传递到Angular2,ngc显示一些错误。我的问题是如何使用ngFactory获取ngc个文件。

详细信息:我正在使用cookbook guide,正在运行"node_modules/.bin/ngc" -p tsconfig-aot.json向我显示以下错误:

Error: Cannot determine the module for component AppComponent!

/// <reference path="../../typings/index.d.ts" />


import {platformBrowserDynamic} from "@angular/platform-browser-dynamic";
import {createMainModule} from "./app.module";

export const main = (SERVER_CONFIG) => {
    platformBrowserDynamic().bootstrapModule(createMainModule(SERVER_CONFIG));
};

app.module.ts:

import {NgModule} from "@angular/core";
import {BrowserModule} from "@angular/platform-browser";
import {AppComponent} from "./app/app.component";
import {routing} from "./app.routing";
import {HttpModule} from "@angular/http";

import {ConfigService} from "./config.service";
import {CustomersModule} from "./customers/customers.module";

export const createMainModule = (SERVER_CONFIG) => {

    @NgModule({
        imports: [
            BrowserModule,
            routing,
            HttpModule,
        ],
        declarations: [AppComponent],
        providers: [
            AuthService,
            {

                useValue: SERVER_CONFIG
            },
            ConfigService
        ],
        bootstrap: [AppComponent]
    })
    class AppModule {
    }
    return AppModule;
};

app.component.ts:

import {Component, OnInit} from "@angular/core";
import {ConfigService} from "../config.service";
import {AuthService} from "../auth.service";
import {Router} from "@angular/router";

@Component({
    selector: 'tt-app',
    templateUrl: 'partials/app/app.component'
})
export class AppComponent implements OnInit {

    user;

    constructor(private _configServer: ConfigService,
                private _authService: AuthService,
                private _router: Router) {
    }

    ngOnInit(): void {
        this.user = this._configServer.server.user;
    }

    logout() {
        this._authService
            .logout()
            .then((result)=> {
            })
            .catch((error)=> {
                this._router.navigate(['/login']);
            });
    }

}

更新1:正如评论中所提到的,我验证了如果删除静态提供程序的代码,我用于将数据从servver传递到Angular2,即应用程序中的createMainModule()。 module.ts等等,然后ngc工作正常。

更新2:我使用SystemJS作为模块加载器。

AppComponent添加到bootstrap而不是AuthComponent,并将AppComponent添加到declarations

@NgModule({
    imports: [
        BrowserModule,
        SharedModule,
        authRouting,
        LoginModule
    ],
    providers: [
        AuthService,
        {
            provide: "SERVER_CONFIG",
            useValue: SERVER_CONFIG
        },
        ConfigService
    ],
    declarations: [AppComponent, AuthComponent],
    bootstrap: [AppComponent]
})
class AuthModule {
}

我得到了同样的错误。我试图在--prod模式下构建它。

然后我尝试了: - ng build --env = prod 。它对我有用。

当您使用第三方库并在顶部尝试AOT时,也可能会导致这种情况,请查看以下链接
