Cannot find module 'rxjs-compat/Observable'

Question

I am currently upgrading angular 4 to angular 6 code. I have installed \"rxjs\": \"^6.3.2\" and un-installed rxjs-compact as I have migrated the code to use the new rxjs ope

Answer 1

npm install --save rxjs-compat

import { Observable } from 'rxjs'

run server ng serve worked for Me

Answer 2

As, Jandro Rojas, already said, installing rxjs-compat dependency it's only a temporary walkaround. In the future, you still need to fix that. The best solution is to use an Angular update guide https://update.angular.io/ because of some mistakes can be fixed automatically.

From my experience with errors "Cannot find module 'rxjs-compat/Observable'", "Cannot find module 'rxjs-compat'" and etc.

• You should fix all the imports. From:

import { Observable } from 'rxjs/Observable'

To:

import { Observable } from 'rxjs'

• If you use RxJS observables classes or etc, you need to update your code. Use this guide -> RxJS v5.x to v6 Update Guide

• Check carefully your dependencies, it should be updated too to use the newest RxJs. In my case "ngx-bootstrap" was outdated.

Answer 3

I am using Angular 10,this method works for me.

npm install --save rxjs-compat

you should import observable this way:-

import { Observable } from 'rxjs/Observable';

Answer 4

npm install --save rxjs-compat

and run the server again with ng serve

This works for me.
