[英]How lazy load an external module in Angular 5?
I'm trying to lazy load an external module (I wrote) into a main application, and I've got some errors, but first of all I wanted to ask you whether I have to build into /dist the external module first, or I have to use the source files?我正在尝试将外部模块(我编写的)延迟加载到主应用程序中,但我遇到了一些错误,但首先我想问您是否必须先将外部模块构建到/dist中,或者我必须使用源文件吗?
Both main and external app/module are written with Angular 5主要和外部应用程序/模块都是用 Angular 5 编写的
Error:错误:
ERROR in Error: No NgModule metadata found for 'AppModule'.

You have to write a wrapper module for this external module and then lazy load this wrapper module.您必须为此外部模块编写包装器模块,然后延迟加载此包装器模块。 Angular doesn't load external node modules as lazy module so I followed same approach
Angular 不会将外部节点模块加载为惰性模块,因此我采用了相同的方法
