我将项目从 4.0.2 升级到最新的稳定版 Angular 5.0.0，这样，我也更新了所有其他依赖项。（我不确定我是否应该先升级到 4.4.6，让 Angular 项目与所有依赖项一起工作真的变得很痛苦:(（）现在，当我运行ng serve时，出现以下错误：

我查看了 Angular 5 更改日志，我没有看到我需要进行的任何更改。
我已经更新了所有依赖项。
我寻找错误，但没有找到太多关于它的信息。如果有人遇到类似的问题，请分享，并且升级角度5.0.0有更好的解决方案

我假设您正在尝试从路由配置中的 users/users.module.ts 延迟加载模块。
我看到了同样的问题。对我来说，从loadChildren路由配置中删除 .ts 扩展名解决了这个问题：
例如
{ path: 'main', loadChildren: 'app/main/index.ts#MainModule'}
成为：
{ path: 'main', loadChildren: 'app/main/index#MainModule'}
我有同样的问题。我正在懒洋洋地加载模块。这工作正常，直到我尝试使用角度材质组件，其中一些存在兼容性问题。我将所有@angular依赖项升级到 5.0.0。现在我收到这个AOT错误。
const appRoutes: Routes = [
{ path: "**", component: NotFound404, pathMatch: 'full' },
{ path: 'expense', loadChildren: 'src/expense/expense.module#ExpenseModule' },
{ path: 'user', loadChildren: 'src/user/user.module#UserModule' }
];
奇怪的是，如果我注释路由中的最后 2 行，这些行懒惰地加载模块，我的项目运行良好。如果我取消注释，那么 webpack 可以很好地重新编译我的项目，并且一切也运行良好。
我无法弄清楚。
有人有解决这个问题的方法吗？
谢谢。迪帕克
