找不到使用“ Ionic g provider”生成的模块

Question

I generated a provider in Ionic CLI as below:

C:\\Ionic\\myApp>ionic g provider DataService

[OK] Generated a provider named DataService!

However, when I try to import that in app.module.ts as below:

 import { HttpModule } from '@angular/http'; import { DataService } from '../providers/data-service'; 

I get an error saying

Cannot find module '../providers/data-service'

app.module.ts is located @ src/app/app.module.ts and the path ' ../providers/data-service ' to data service is correct from its location.

Can anyone please suggest where am I going wrong here?

Answer 1

The path should include the file name as well without .ts :

import { DataServiceProvider } from '../providers/data-service/data-service';

But normally ionic g does this for you, unless you used the --no-module option.
