Error when using npm install angular2 --save

Question

I'm following along in a Tuts+ tutorial on Angular. In this video: https://code.tutsplus.com/courses/whats-new-in-angular-2/lessons/angular-2-and-es5 the author says to type the following command:

npm install angular2 --save

I tried that, as well as using sudo in front of it as well, but get the following errors:

npm ERR! notarget This is most likely not a problem with npm itself.
npm ERR! notarget In most cases you or one of your dependencies are requesting
npm ERR! notarget a package version that doesn't exist.

thoughts?

The author is able to do it fine without errors:

You can do npm install angular2@SPECIFIC_VERSION where SPECIFIC_VERSION is one of the shown in the error, or use npm install angular2@latest --save — Eric Martinez

To install angular2 using npm you can either specify the version or use @latest

Specifying a version

npm install [email protected] --save

Using latest (this will obviously install the latest version available in npm)

npm install angular2@latest --save

Note as well that there are plans to support angular@next that would add the posibility to install nightly builds, but it's not yet supported (so far snapshots are released from time to time, but the command is not yet available). Check issue #4671 for more info.
