Version 0.3.3 is offered to Python 2.7's pip, which is wrong as it isn't compatible. This clause should prevent pip from trying to install this version. More info at https://stackoverflow.com/a/42792413/1076564 .
I'm not sure how exactly it behaves, but it's possible that version 0.3.3 would need to be re-released with this fix, or a new version released and 0.3.3 withdrawn.
