Question

Angular 9项目失败尝试编译可在Angular 8中使用的代码。

node_modules/@angular/core/src/render3/ng_dev_mode.d.ts（9,11）中的错误：错误TS2451：无法重新声明块作用域变量'ngDevMode'。 ../../../node_modules/@angular/core/src/application_ref.d.ts(8,28）：错误TS2307：找不到模块“ rxjs”。 ../../../node_modules/@angular/core/src/event_emitter.d.ts(8,39）：错误TS2307：找不到模块“ rxjs”。 ../../../node_modules/@angular/core/src/linker/query_list.d.ts(8,28）：错误TS2307：找不到模块'rxjs'。 ../../../node_modules/@angular/core/src/render3/ng_dev_mode.d.ts(9,11）：错误TS2451：无法重新声明块作用域变量'ngDevMode'。 ../../../node_modules/@angular/core/src/util/lang.d.ts(8,28）：错误TS2307：找不到模块“ rxjs”。 ../../../node_modules/@angular/http/src/backends/jsonp_backend.d.ts(8,28）：错误TS2307：找不到模块'rxjs'。 ../../../node_modules/@angular/http/src/backends/xhr_backend.d.ts(8,28）：错误TS2307：找不到模块'rxjs'。 ../../../node_modules/@angular/http/src/http.d.ts(8,28）：错误TS2307：找不到模块“ rxjs”。

我将问题隔离到正在加载的服务上。

import { Injectable } from '@angular/core';
import { Http, Response } from '@angular/http';
import { Observable, throwError } from 'rxjs';
import { map, takeUntil, tap, catchError } from 'rxjs/operators';
import * as Global from './global';
import { HttpClient } from '@angular/common/http';
import { HttpHeaders } from '@angular/common/http';
import { HttpErrorResponse } from '@angular/common/http';

    "tslint": "~5.11.0",
    "typescript": "~3.2.2"
  }
}

还尝试了通常的升级打字稿，rxjs和角度组件的混合操作。

任何帮助将不胜感激！

------------------ UPDATE -------------

是的，@ phix在第二条评论中是完全正确的，它仍然是版本7。我假设将全局更新（ npm install @ angular / cli @ 9.0.0 -g ）升级到9，然后创建一个项目将自动创建版本9项目-错误的假设。

我使用该信息正确升级了我的项目 https://levelup.gitconnected.com/upgrade-to-angular-9-within-10-minutes-671c6fd6174b
