如何解决这个错误无法解决rxjs / Rx＆＃39;

Question

编译失败。

./ SRC /应用/服务/ admin.service.ts 找不到模块：错误：无法解析rxjs / Rx＆＃39;在＆C; \ project \ test-m \ angular \ src \ app \ services＆＃39;

的package.json ＆＃34; rxjs＆＃34;：＆＃34; ^ 6.0.0＆＃34;，

Answer 1

使用

import { Observable } from 'rxjs';

代替

import { Observable } from 'rxjs/Rx';

Answer 2

我解决了这个问题

app.module.ts

从＆＃39; @ angular / common / http＆＃39;中导入{HttpClientModule};

进口：[

HttpClientModule,

]，

service.ts

从＆＃39; @ angular / common / http＆＃39;中导入{HttpClient，HttpHeaders};

从＆rxjs /运算符＆＃39;;

导入{map}

构造函数（私有http：HttpClient）{}

  getlogin(username: string, password: string) {
    return this.http.post('http://localhost:3000/auth/login', { username: username, password: password })
        .pipe(map(user => {
            return user;
        }));
}

components.ts

this.adminService.getlogin(this.login.email,this.login.password)
    .pipe(first())
    .subscribe(
        data => {
          console.log(data)
        },
        error => {
          console.log(error)
        });
