问题描述
我使用 ng update 将我所有的 angular 库升级到 angular 9.0.0，当我尝试构建它们时，出现以下错误.
I upgraded all my angular library to angular 9.0.0 using ng update and when I try to build them I got below error.
错误:
不受支持的私有类 SomeComponent.此类通过 SomeModule -> SomeComponent 对消费者可见，但不会从顶级库入口点导出.
有人解决了这个错误吗?
Anyone solved this error?
推荐答案
如果任何组件在 NgModule 中导出并且未包含在您的 public_api.ts 中，则会发生此错误，Angular 9 现在会抛出错误.
This error happens if any component is exported in NgModuleand not included in your public_api.ts, Angular 9 will throw an error now.
这个错误不是在 Angular 8 中出现的，但在升级到 Angular 9 后它开始显示.
This error was not coming in Angular 8 but after upgrading to Angular 9 it started showing.
如果您在 NgModule 中导出了任何 service、module 或 component 等，请确保将它们包含在public_api.ts 否则 angular 9 现在会抛出错误.
If you exported any service, module or component, etc in NgModule make sure to include them in public_api.ts or else angular 9 will throw error now.
修复:将您的组件添加到public_api.ts
export * from './lib/components/some-me/some-me.component';
这篇关于消费者可以通过 SomeModule 看到这个类 ->SomeComponent，但不是从顶级库入口点导出的文章就介绍到这了，希望我们推荐的答案对大家有所帮助，也希望大家多多支持！
