importing angular2/http in ionic 2 has error "cannot find module"

ok, i found a solution,

in Ionic 2, Beta 7, we should use:

import {Http} from '@angular/http';

Just in case if this could be useful to someone, there are some other changes you would need to do in order to upgrade to Ionic 2 beta 7 (or beta 8 now).

You can take a look at the recommended steps (and breaking changes like that one) here.

=========

EDIT:

As Bond - Java Bond suggests, these are the breaking changes in case of the link goes dead:

2.0.0-beta.7 (2016-05-19) BREAKING CHANGES

Angular Update to 2.0.0-rc.1

Angular has been updated to 2.0.0-rc.1, follow these steps to update Angular.

1. Edit your package.json and remove the angular2 entry:

   "angular2": "2.0.0-beta.15"
   

2. Then, run the following command from a terminal to update Ionic and Angular, or take a look at the starter's package.json changes and update each version:

   npm install --save [email protected] @angular/core @angular/compiler @angular/common @angular/platform-browser @angular/platform-browser-dynamic @angular/router @angular/http [email protected] [email protected] reflect-metadata
   

3. Run the following command from a terminal to update the gulp task for ionic-gulp-scripts-copy:

   npm install --save-dev [email protected]
   

4. Then, change any imports in your application from angular2 to @angular. For example, the following.

   import {ViewChild} from 'angular2/core';
   import {Http} from 'angular2/http';
   

   becomes

   import {ViewChild} from '@angular/core';
   import {Http} from '@angular/http';
   

5. Remove the import for angular2-polyfills in index.html:

   <script src="build/js/angular2-polyfills.js"></script>
   

   and replace it with the following scripts:

   <script src="build/js/zone.js"></script>
   <script src="build/js/Reflect.js"></script>
   

6. Replace all template variables in ngFor with let. For example:

   *ngFor="#session of group.sessions"
   

   becomes

   *ngFor="let session of group.sessions"
   

7. Replace all template variables in virtualScroll. For example:

   *virtualItem="#item"
   

   becomes

   *virtualItem="let item"
