Question

我有一个角度最终应用程序，可以加载很多路径和模块。我开始在控制台中收到“区域已加载”错误，现在我得到它两次。

我查看了区域对象，试图弄清楚发生了什么，但是如果不知道应该做什么区域，这几乎是不可能解密的。

Main.ts

import { platformBrowserDynamic } from '@angular/platform-browser-dynamic';
import { enableProdMode } from '@angular/core';

import { environment } from './app/';
import {AppModule} from './app/app.module';

enableProdMode();

platformBrowserDynamic().bootstrapModule(AppModule,[]);

app.module.ts（我省略了所有导入）：

@NgModule({

    imports: [ BrowserModule, RouterModule.forRoot(appRoutes), SharedModule.forRoot(), 
               HomeModule, DocumentsModule, AboutModule, SettingsModule, FoodModule, CalculatorModule, 
               ThemesModule ],
    declarations: [ AppComponent ],
    bootstrap: [ AppComponent ],
    providers: [ appRoutingProviders ]

}) 

export class AppModule {}

app.component.ts

@Component({
    moduleId: module.id,
    selector: 'kg-root',
    templateUrl: 'app.component.html',
    styleUrls: ['app.component.css']

})

export class AppComponent implements OnInit {
    private items: MenuItem[];
    appPageHeaderDivStyle: {};
    selectedTheme: Theme;
    errorMessage: string;
    loggedIn: LoggedIn;
    loggedInEmail: string = "";
    isLoggedIn: boolean;

    constructor(
        private as: AppMenuService,
        private ts: ThemeService,
        private ss: SettingsService,
        private ls: LoginService) {
    }

    ngOnInit() {

        this.ts.getNewTheme()
            .subscribe(
            theme => this.selectedTheme = theme,
            error => {
                this.errorMessage = error
            },
            () => this.completeGetNewTheme()
            );

        this.ts.setTheme("Pepper-Grinder");
        this.items = this.as.getNoLoginMenu();

        this.ls.getLoggedIn()
            .subscribe(
            loggedIn => {
                if (loggedIn.error != undefined && loggedIn.error === "" && loggedIn.email != "") {
                    this.items = this.as.getLoggedInMenu();

                    var us = this.ss.getUserSettings();
                    if (us != undefined && us.theme != null && us.theme != "") {
                        this.ts.setTheme(us.theme);
                    }
                }
                else {
                    this.items = this.as.getNoLoginMenu();
                    this.ts.setTheme("Pepper-Grinder");
                }

                this.completeLoggedIn(loggedIn.email);
            });
    }

    completeLoggedIn(email: string) {
        this.loggedInEmail = email;
        this.isLoggedIn = (this.loggedInEmail.length > 0);

    }

    completeGetNewTheme() {
        this.appPageHeaderDivStyle = this.ts.getAppPageHeaderDivStyle();
    }

我认为这个错误意味着已经加载了一些给定的区域。看来这意味着＆＃34; zone.js＆＃34;已经装好了。当我切换到Angular-cli时，它已经加载到angular-cli-build.js中。所以从index.html中删除它解决了这个问题。

我发布此邮件以防其他人遇到错误。

如何确定已加载的区域？
