当我编译时,我在RxJS声明文件中得到以下编译器错误:

node_modules/rxjs/Subject.d.ts(16,22): error TS2415: Class 'Subject<T>' incorrectly extends base class 'Observable<T>'.
  Types of property 'lift' are incompatible.
    Type '<R>(operator: Operator<T, R>) => Observable<T>' is not assignable to type '<R>(operator: Operator<T, R>) => Observable<R>'.
      Type 'Observable<T>' is not assignable to type 'Observable<R>'.
         Type 'T' is not assignable to type 'R'.

这里发生了什么,如何在不降级到TypeScript 2.3或更早版本的情况下解决这个问题？

#这是我现在面临的错误:

我使用npm(https://github.com/shripalsoni04/nativescript-angular-drawer-template)下载了导航抽屉样本.但它会出现以下错误.

我有一个简单的服务,内容如下:

import { Injectable } from '@angular/core';
import { Http, Response } from '@angular/http';

import 'rxjs/add/observable/throw';
import 'rxjs/add/operator/catch';
import 'rxjs/add/operator/map';
import { Observable } from 'rxjs/Observable';

@Injectable()
export class AddressService {

  constructor(private http: Http) { }

  getAnything = (): Observable<Response> => {
    return this.http.get('https://my_api.com')
      .map(this.handleSuccess)
      .catch(this.handleError);
  }

  handleError = (error: Response): Observable<Response> => {
    return Observable.throw(error || 'Server Error');
  }

  handleSuccess = (response: Response): Observable<Response> => {
    let body;

    if (response.text()) {
      body = response.json();
    }

    return body || {}; …

我有一个Angular应用程序,它完美地运行.但是,使用后升级依赖项后yarn upgrade,我得到了这个神秘的错误:

为了防止downvotes,我将lorem-ipsum详细说明此错误消息:

我正在使用angular4和蓝色(实际上它今天相当灰)这个错误发生了.有人可以帮忙吗？我已经在github上发现了类似的问题,但没有解决问题的答案(我尝试过"npm update"和"npm install")

打字稿版本是2.4.0

其他错误消息是:

类'WebSocketSubject'错误地扩展了基类'AnonymousSubject'

物业'电梯'的类型是不相容的.

原始错误区域的位置为"./node_modules/rxjs/Subject.d.ts".
