ok, i found a solution,

in Ionic 2, Beta 7, we should use:

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

Answer 2

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 ionic-angular@2.0.0-beta.7 @angular/core @angular/compiler @angular/common @angular/platform-browser @angular/platform-browser-dynamic @angular/router @angular/http rxjs@5.0.0-beta.6 zone.js@0.6.12 reflect-metadata 

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

    npm install --save-dev ionic-gulp-scripts-copy@2.0.0 

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" 

8. View the Angular Changelog for more in depth changes.
