angular5 rxjs/Observable/of报错

报错信息：

ERROR in ./src/app/auth.service.ts
Module not found: Error: Can't resolve 'rxjs/Observable/of' in 'D:\eclipse-workspace\dqgy\dqgy\manage\src\app'

解决办法：

import { Observable } from 'rxjs';
import { of } from 'rxjs';

分开导入，如下所示：

import { Observable } from 'rxjs/Observable';
import { of } from 'rxjs/observable/of';
