Unable to find ionic version after updating ionic 1 to ionic 2 (error on shell.js)

I am working on windows10 for my ionic1.

I tried to install ionic2 in my pc and i am not able to create my ionic project and i am not able see the version of ionic

I don’t see anything related to ionic.

When i try to get the version of ionic using this command ionic -v i am not able to get my version i am getting the error which i have placed in the below [image][1]

things i did so far is done is command for installing ionic 2 npm install -g ionic@beta

Before entering the above command i was able to work with ionic1 good.

Hmm, look like something happened.

Could you provide the output from node -v and npm -v?
