Hello guys, I have create a service business file is StudentService, and I want to get a list of students.
I used Observable and of to help me return a list of students. Like this:
import { Injectable } from '@angular/core';
import { Observable } from 'rxjs/Observable';
import { of } from 'rxjs/observable/of';
import { Student } from './hero';
import { Students } from './mock-students';
@Injectable({
providedIn: 'root'
})
export class StudentService {
constructor() {
// Initial variable here
}
getStudent(): Observable<Student[]> {
return of(Students);
}
}
But when call method getStudent() I got an exception 'rxjs/Observable' has no exported member 'Observable'.
error TS2307: Cannot find module 'rxjs-compat/Observable'. node_modules/rxjs/observable/of.d.ts(1,15):
error TS2307: Cannot find module 'rxjs-compat/observable/of'. src/app/student.service.ts(2,10):
error TS2305: Module '"F:/learn-angular/node_modules/rxjs/Observable"' has no exported member 'Observable'. src/app/student.service.ts(15,12):
error TS2304: Cannot find name 'of'.
How can I resolve it?

I think you only need to import the parent package. You can change:
import { Observable } from 'rxjs/Observable';to
import { Observable } from 'rxjs';In your service, you can do as below:
import { Observable, of } from 'rxjs';I hope it works for you.

Sometimes I have to try to run
npm updateand npm installrxjs-compat --saveand it works for me.If it still does not work you can try to delete
node_modulesfolder first.
