管道（地图）的角度问题

Question

我正在尝试学习平均堆栈，但我运行遇到了此代码的问题。

它在编译时出现此错误，如果您对如何解决这个问题有想法，我们将不胜感激

 getPosts() {
    this.http
      .get<{ message: string; posts:any }>(
        "http://localhost:3000/api/posts"
      )
      .pipe(map((postData) => {
        return postData.posts.map(post => {
          return {
            title: post.title,
            content: post.content,
            id: post._id
          };
        });
      }))
      .subscribe(transformedPosts => {
        this.posts = transformedPosts;
        this.postsUpdated.next([...this.posts]);
      });
  }

错误：src/app/posts/posts.service.ts:20:13 - 错误 TS2345：'import("C:/Windows/System32/metric-server/node_modules/rxjs/dist/types/internal/types").OperatorFunction<{ message: string; posts: any; }, any>' 类型的参数不可分配给 'import("C:/Windows/System32/node_modules/rxjs/dist/types/internal/types").OperatorFunction<{ message: string; posts: any; }, any>'.[=11 类型的参数=]

Answer 1
