这个类通过 SomeModule 对消费者可见 ->SomeComponent，但不是从顶级库入口点导出 [英] This class is visible to consumers via SomeModule -> SomeComponent, but is not exported from the top-level library entrypoint

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.

Unsupported private class SomeComponent. This class is visible to consumers via SomeModule -> SomeComponent, but is not exported from the top-level library entrypoint.

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 后它开始出现.

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';
