Failed to install bower/fullcalendar - Could not parse version constraint

[marcovtwout]

I'm not sure if this is an issue with this plugin or the external dependency.

When I run: composer require bower-asset/fullcalendar -vvv

I get the following error: Could not parse version constraint >=~2: Invalid version string "~2"

Full console output:

$ composer require bower-asset/fullcalendar -vvv
