Module build failed: Error: ENOENT: no such file or directory

Hi, I am getting this error when trying to import IonCalendarModule and serve the App whith ionic serve in the browser:

Module build failed: Error: ENOENT: no such file or directory, open '/Users/MACDan/Documents/MyApp/node_modules/@ionic2-extra/calendar/index.js.map' at Error (native)

This is what I have in my app.modules.ts:
...
import { IonCalendarModule } from "@ionic2-extra/calendar";
...
imports: [
IonicModule.forRoot(MyApp),
IonCalendarModule
],
...

This is what I have installed:
Ionic Framework: 2.1.0
Ionic Native: 2.4.1
Ionic App Scripts: 1.1.3
Angular Core: 2.2.1
Angular Compiler CLI: 2.2.1
Node: 6.9.2
OS Platform: macOS Sierra
Navigator Platform: MacIntel

Also I installed this module like this:

npm install ../../Downloads/ionic2-extra-master/src/lib/calendar

Did I do something wrong?
