消费者可以通过SomeModule->看到此类.SomeComponent，但不是从顶级库入口点导出的 [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 将我所有的角度库升级到了 angular 9.0.0 ，当我尝试构建它们时，出现了以下错误.

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.消费者可以通过SomeModule-> SomeComponent看到此类，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

如果将任何组件导出到 NgModule 中且未包含在 public_api.ts 中，则会发生此错误，角度9 现在会出错.

This error happens if any component is exported in NgModuleand not included in your public_api.ts, angular 9 will through error now.

此错误不是在 angular 8 中出现的，但是在升级到 angular 9 之后，它开始显示.

This error was not coming in angular 8 but after upgrading to angular 9 it started showing.

如果在 NgModule 中导出了任何 service ， module 或 component 等，请确保将它们包括在 public_api.ts 或 angular 9 现在会引发错误.

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

Fix: add your component to the public_api.ts

export * from './lib/components/some-me/some-me.component';
