属性"of"在类型"typeof Observable"上不存在 [英] Property 'of' does not exist on type 'typeof Observable

问题描述

我最近在我的身份验证令牌上使用了可观察的

I was recently using observable on my authentication token like

Observable.of('token');

尽管我已经导入了它，但是它一直给我上述错误.

But it keeps giving me above mentioned error, though i have already imported this.

import {Observable} from 'rxjs/Observable';

推荐答案

您需要导入它:

对于Angular> = 6.0.0

使用RxJS 6.0.0 Angular Changelog 6.0 .0

uses RxJS 6.0.0 Angular Changelog 6.0.0

import { of } from 'rxjs';

并且其用法已更改，您不再将其称为Observable:

And its usage has been changed, you no longer call it off of Observable:

of('token');

用于Angular< = 5.x.xx

import 'rxjs/add/observable/of';

它和您在问题中所使用的一样

And it's used as you have in your question

Observable.of('token');
