Facebook Plugin Runtime Error

I’ve installed the Facebook plugin (http://ionicframework.com/docs/native/facebook/), and now I’m getting this error below. I know this should be something to do with me forgetting something small, but don’t recall what. Any help will be highly appreciated!!

Runtime Error
Cannot read property 'prototype' of undefined

Hi @dimitri320

Some issue in
this error when generated you install npm and some update of npm this issue will happen

check your npm version using npm -v

go to node_modules/@ionic-native/facebook/index.d.ts this path and send here code


These two have to be of the same version, and then all works. So I had to update these.

  "@ionic-native/core": "^3.6.1",
    "@ionic-native/network": "^3.6.1",
