Error when running the command yo angular2

I've followed as per your tutorials and find the following error when running yo angular2.

Error angular2 

You don't seem to have a generator with the name angular2 installed.
You can see available generators with npm search yeoman-generator 
and then install them with npm install [name].

The yo and angular-generator has been installed using the following command:
npm install -g yo generator-angular2

[Ariestattoo]

what happens when you simply type yo in the console? Is it in the available list?

[chrisdwheatley]

Yeah it sounds like the installation may have failed, try re-running npm install -g yo generator-angular2 and see if there are any errors reported.

@Ariestattoo when typed yo the following menu comes up:

  Ionic 
  Mobileangularui 
  Webapp 
  Karma 
(Move up and down to reveal more choices)

@swirlycheetah I've run the command sudo npm install -g yo generator-angular2 many times, before posting this bug and even as I'm typing :(

[Ariestattoo]

In general it would be preferable not to run the install as a superuser. What output are you receiving when running the install as swirlycheetah recommended?

It looks like without sudo the install is failing due to permission issues. When you run sudo npm install -g generator-angular2 what is the output in the console?

[vuxor]

If you are trying to install with "-g" flag that means it will be installed globally on your system and that's why you need to run this command with "sudo".

@swirlycheetah when using sudo npm install -g generator-angular I get the following:

 yo@1.7.0 postinstall /usr/local/lib/node_modules/yo

I'm not entirely sure but it looks like if you've installed the generator with sudo and the try running yo command without it then you don't have permission to use the generator. You don't need sudo to install modules globally. Some resources which may help you out:

Sorry with delayed post, my modem was under repair :)
