MatIconModule 不再在库中编译

Question

我正在尝试在 Angular 包格式库中使用 MatIconModule，当我引入 MatIconModule 时，它无法编译。要亲自查看，请克隆 MVCE 存储库：

git clone git@github.com:fireflysemantics/maticonmoduleerror.git
cd maticonmoduleerror
npm i
ng build --prod fs-assets

这是模块的样子：

import { NgModule } from '@angular/core';
import { MatIconModule } from '@angular/material/icon';

@NgModule({
  declarations: [
  ],
  imports: [MatIconModule
  ],
  exports: [
  ]
})
export class FsAssetsModule { }

如果删除 MatIconModule，它会编译。 Angular Material 以 ng add @angular/material 的标准方式添加到根项目中。这些是编译器错误：

> ole@mkt:~/Temp/clone/maticonmoduleerror$ ng build --prod fs-assets

这曾经工作得很好。有什么想法吗？

您的项目仍在使用 Angular 11，请参阅链接存储库中的 package.json。使用 ng update @angular/core @angular/cli @angular/material 更新到 Angular 12 应该可以解决这个问题。

MatIconModule 不再在库中编译

MatIconModule no longer compiles in libraries

javascript

typescript
