问题描述

这可能意味着声明HttpClient的库(@angular/common/http)未被ngcc正确处理，或者与Angular Ivy不兼容.检查是否有较新版本的库，如果有，则进行更新.还可以考虑与图书馆的作者进行核对，以查看该图书馆是否与Ivy兼容.

This likely means that the library (@angular/common/http) which declares HttpClient has not been processed correctly by ngcc, oris 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 Check if a newer version of the library is available, and update if so.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.

81 export declare class HttpClient {

推荐答案

也许您已导入HttpClient而不是HttpClientModule.检查app.module.ts

Maybe you have imported HttpClient instead ofHttpClientModule.Check imports in app.module.ts

imports: [
    BrowserModule,
    AppRoutingModule,
    BrowserAnimationsModule,
    MatToolbarModule,
    FlexLayoutModule,
    HttpClientModule
  ],
