Question

我收到错误消息：找不到模块

'src/app/settings/settings.module'.
    at eval (eval at ./src/$$_lazy_route_resource lazy recursive

尝试从我的api添加延迟加载的模块时。使我难以调试的原因是，当我在StackBlitz上尝试此操作时，它似乎运行良好。这是我的项目的链接：Dynamic routes from API 但是，当我将项目移出StackBlitz并在我的PC上重新创建它时，会出现错误。

重要的是要提到，当我发布来自以下API的路由时，您会看到对于延迟加载的模块（settings.module），它们在“ app”之前包含“ src”，这仅是因为StackBlitz有一个嵌套的“ src”文件夹。另外，如果您尝试导出我的项目，则需要将目录“ src”添加到angular-cli.json文件的“ main”属性中。我不确定这可能会如何影响模块。我已经待了好几天了，任何帮助将不胜感激。

我正在使用这样的服务：

import {
  Injectable,
  Compiler,
  NgModuleFactory,
  NgModuleFactoryLoader,
  Injector,
  NgModuleRef,
} from '@angular/core';
import { Router } from '@angular/router';
import { ApiRoute } from '../models/apiroutes.interface';

@Injectable()
export class ModuleFactoryLoader {
  private moduleRef: NgModuleRef<any>;
  constructor(
    private loader: NgModuleFactoryLoader,
    private injector: Injector,
    private router: Router,
  ) {
  }

  load(apiRoute: ApiRoute): void {
    this.loader.load(apiRoute.loadChildren).then(moduleFactory => {
      this.moduleRef = moduleFactory.create(this.injector).instance;
      this.router.config.unshift({
        path: apiRoute.path,
        loadChildren: apiRoute.loadChildren,
      });
      console.debug('moduleRef', this.moduleRef);
    }).catch(err => {
        console.error('error loading module', err);
      });
  }
}

和来自我的（模拟）api的路线是：

[
{
path: "test",
component: "TestComponent",
data: {
icon: "check"
}
},
{
path: "settings",
loadChildren: "src/app/settings/settings.module#SettingsModule"
},
{
path: "home",
component: "HomeComponent",
data: {
icon: "home"
}
},
{
path: "self-service",
component: "RouteSelfServiceComponent",
data: {
icon: "build"
}
}
]

在我的电脑上运行的Angular的版本是：

这里是产生的错误（仅本地错误。StackBlitz没有问题）：

Answer 1

您无法使用Angular CLI来完成您想做的事情，因为Angular CLI构建不会编译未引用的模块。

在构建项目时，没有SettingsModule关联的JS块，除非在运行时之前定义了路线。

我找到了一个演示项目，它可以完成您尝试做的事情here，但是它没有使用Angular CLI构建，而是使用了tsc && concurrently \"tsc -w\" \"http-server . -c-1 \"。

我不知道StackBlitz使用哪个构建管道，但是肯定不是Angular CLI。

您只能尝试打字稿编译，但是它不能解决AOT生产版本的问题，您将被迫使用自己的自定义版本

Answer 2

我设法使其在本地工作，这就是我所做的：

ng new myFirstApp

然后我将app文件夹复制到了新的angular 6项目中，并将angular-cli.json重命名为angular.json

与router-loader.service.ts中一样，我无法使它复制的API_ENDPOINTS起作用

 of([
    {
      "path": "test",
      "component": "TestComponent",
      "data": {
        "icon": "check"
      }
    },
    {
      "path": "settings",
      "loadChildren": "src/app/settings/settings.module#SettingsModule"
    },
    {
      "path": "home",
      "component": "HomeComponent",
      "data": {
        "icon": "home"
      }
    },
    {
      "path": "self-service",
      "component": "RouteSelfServiceComponent",
      "data": {
        "icon": "build"
      }
    }
  ])
.toPromise()...
