HTTP plugin is not installed error with ionic

If you do not want to modify the ionic-native plugin like suggested by @alpere or if the solution does not work you can always use the cordova plugin without ionic-native. To do so tell typescript that the http handle exists by adding the following somewhere below your imports:

declare var http;

And then use it like this:

http.get(
  'https://ionic.io/',
  {},
  {},
  response => {
    console.log(response.status);
  },
  response => {
    console.error(response.error);
  },
);

Note that there is no need of this because cordova plugins are defined on a global scope. The downside of using plugins without the ionic-native wrapper is that you loose the nice type annotations, promise callbacks and in some cases you will have to trigger angular change-detection yourself.

The Ionic Native HTTP changed the cordova plugin they are using since the old one hasn't been updated for a while. During the change the reference to the plugin has't been updated so it's broken. (See: https://github.com/silkimen/cordova-plugin-advanced-http/issues/8)

You can fix it by changing the old referenced plugin to new one: (After the commit also updating the plugin will fix the issue)

in @ionic-native/plugins/http/index.ts:

change:

pluginRef: 'cordovaHTTP',

to:

pluginRef: 'cordova.plugin.http',
