Error composing FullCalendar

I get an error when I try to add FullCalendar to my composer.json

[UnexpectedValueException] Could not parse version constraint >=~2: Invalid version string "~2"

When I remove the FullCalendar from my require section everything works fine. I'm not exactly a composer wizard so any help would be useful.
