How can I resolve this?

Answer 1

Angular 2 is in a different package than angular 1: https://www.npmjs.com/package/angular2

For example, you could install it using npm install angular2 .

Answer 2

To install Angular2 you can use the command npm install angular2 . Another way of doing it is to add the package and version number to your package.json file. For example:

...
"dependencies": {
    "angular2": "2.0.0-beta.17"`
}
...

You then need to run npm install in your project root.

However .... I wouldn't use the Angular2 npm package, because it's a little out of date now (at the time of writing, this may change after full release). The development team has split the main areas of functionality into separate sub-packages. To use these you will need to import them individually into your package.json file. For Example:

...
"dependencies": {
    "@angular/common": "2.0.0-rc.4",
    "@angular/compiler": "2.0.0-rc.4",
    "@angular/core": "2.0.0-rc.4",
    "@angular/forms": "0.1.1",
    "@angular/http": "2.0.0-rc.4",
    "@angular/platform-browser": "2.0.0-rc.4",
    "@angular/platform-browser-dynamic": "2.0.0-rc.4",
    "@angular/platform-server": "2.0.0-rc.4",
    "@angular/router": "3.0.0-beta.2"
}
...

Answer 3

Installation of the current version of Angular 2 is split up into several packages:

• @angular/core
• @angular/common
• @angular/platform-browser-dynamic
• @angular/platform-browser
• @angular/http
• @angular/forms
• @angular/router

Just install all of those with npm install
