Ionic run android error

I just installed ionic but when I try 'ionic emulate android' in the cmd window, I get the following error:

"Error: ENOENT, no such file or directory 'C:\Users...\myapp\plugins\com.ionic.keyboard\www\keyboard.js"

I have tried deleting the project and creating a new one, uninstalling ionic and cordova and reinstalling them, amongst other attempts at fixing the problem and I have not had any success. I looked in the directory in the error message and everything is there until \www\keyboard.js. There is no www folder.

Also, I'm running windows 8. If anyone has any idea how to fix this I would really appreciate it. Thanks!

just create the "www" folder, and retry running ionic emulate android
