angular - MatToolbar 与 Angular 9 一起使用时抛出错误

Question

Angular 版本 9.2.0

当我导入 MatToolbarModule在一个模块中并在 html 模板中使用它，然后我收到以下错误消息:

This likely means that the library (@angular/material/toolbar) which declares MatToolbarModule has not been processed correctly by ngcc, or is not compatible with Angular Ivy. Check if a newer version of the library is available, and update if so. Also consider checking with the library's authors to see if the library is expected to be compatible with Ivy.

8 export declare class MatToolbarModule {
                       ~~~~~~~~~~~~~~~~
src/app/angular-material.module.ts:53:14 - error NG6002: Appears in the NgModule.imports of ComponentsModule, but itself has errors

有没有人面临同样的问题？

Answer 1

在 package.json 中添加以下具体配置和 npm install .

{
  "scripts": {
    "postinstall": "ngcc"
  }
}
