错误：使用ng serve --aot时找不到模块

Question

我将角度项目从6迁移到7，我正在使用延迟加载机制来加载模块。但是，当我进行生产构建或为项目提供服务时，他们的建议为ng serve --aot出现以下错误。

错误：未捕获（承诺）：错误：找不到模块'app / modules / home / home.module'错误：找不到模块'app / modules / home / home.module'

这是我的package.json

}

这是我的app.routing.module.ts

              {
                path: 'home',
                loadChildren: 'app/modules/home/home.module#HomeModule'
              },
              {
                path: 'top',
                loadChildren: 'app/modules/top/top.module#TopModule'
              },
              {
                path: 'story/:storyId',
                loadChildren: 'app/modules/story/story.module#StoryModule'
              },
              {
                path: '',
                redirectTo: 'home',
                pathMatch: 'full'
              }

这是我的目录结构

Project
  src
    app
      app.module.ts
      app.routing.module.ts
      modules
        home
          homedir.module.ts

最后这是我的tsconfig

{
  "compileOnSave": false,
  "compilerOptions": {
    "outDir": "./dist/out-tsc",
    "sourceMap": true,
    "declaration": false,
    "moduleResolution": "node",
    "emitDecoratorMetadata": true,
    "experimentalDecorators": true,
    "target": "es5",
    "typeRoots": [
      "node_modules/@types"
    ],
    "lib": [
      "es2017",
      "dom"
    ],
    "module": "es2015",
    "baseUrl": "./"
  }
}

[Build可以正常工作，但aot为false。但是我确实需要解决这个问题的方法。我也尝试使用绝对路径和loadChildren: () => HomeModule。有什么建议吗？

Answer 1

使用新版本的Angular，我们更喜欢这样编写导入：

loadChildren: () => import('./customers/customers.module').then(m => m.CustomersModule) }

因此，请使用相对路径。
