GemRequirement.py: cmd needs a space after -i
cmd = 'gem list -i' + self.package
this causes GemRequirement("img_checker").is_installed()
return False
when it is installed.
I have tried this in python shell and running that gives me false, where if I run
GemRequirment(" img_checker")
it returns True
This will also cause error for other gem files i think
>>> GemRequirement('rubocop').is_installed()
False
>>> GemRequirement('reek').is_installed()
False
