Bug introduced by
The __init__ method of the super-class PackageRequirement is not called.

It is generally advisable to initialize the super-class by calling its __init__ method:

class SomeParent:
    def __init__(self):
        self.x = 1

class SomeChild(SomeParent):
    def __init__(self):
        # Initialize the super class
        SomeParent.__init__(self)
