问题描述：
更新angular/cli后，出现错误:
After I updated angular/cli, I got an error:
error TS2339: Property 'map' does not exist on type 'Observable<Response>'
我尝试了类型'Observable< Response>'上不存在属性'map'
但是错误仍然存在.
but still the error exists.
答
在提供代码而不是屏幕截图时，很容易发布答案. 无论如何，您必须pipe:
Its easy to post an answer when you provide your code instead of a screenshot. Anyhow, you have to pipe it:
getUsers() {
return this._http.get(this.baseUrl+'/show-users', this.options)
.pipe(
map((response:Response)=>response.json())
);
记住要这样导入map:
import { map } from 'rxjs/operators';
