Rxjs import issues in Angular 6

问题

I am facing some weird issues while working with Angular 6 and Rxjs 6. When I import as below

Import { forkJoin } from 'rxjs/internal/observable/forkJoin';

I am getting issue as

but when I use import as

import { forkJoin } from 'rxjs/';

it works perfectly.

I used the same method to merge operator but when i used import as

import { merge } from 'rxjs/';

but it thrown error as above and it works fine if i use

import { merge } from 'rxjs/internal/observable/merge';

Could someone point out where is the problem? Why is this working differently?

PS: It's working on reloading page but alternately.

回答1:

Use it like this,

import { merge } from 'rxjs/operators';

Check you rxjs version, it should be 6+

回答2:

Use :

 import {merge} from 'rxjs';

OR

import { merge } from 'rxjs/operators';
