Installing ASP.net DNX with Powershell 2.0 - asp.net

Question

I am trying to get an install of ASP.Net DNX on Windows. I followed the instructions at: https://github.com/aspnet/home#cmd
The problem is. when I run this, I get an error stating:

Can I install the DNX with only Powershell 2.0 or do I have to upgrade to 3.0?

The script 'dnvm.ps1' cannot be run because it contained a "#requires" statemen
t at line 2 for Windows PowerShell version 3.0.
If you want to be sure that the script will work, you'll have to use Powershell v3.0. It is certainly possible to modify the script to remove the requirement, but it as probably put there for a good reason. It would just be a roll of the dice if it would actually work if the requirement was removed.
