When i run in shell

>>> from univers.versions import PypiVersion
>>> v = PypiVersion("10.0.2-10.1.0")
Traceback (most recent call last):
  File "<python-input-1>", line 1, in <module>
    v = PypiVersion("10.0.2-10.1.0")
  File "<attrs generated init univers.versions.Version>", line 7, in __init__
    self.__attrs_post_init__()
    ~~~~~~~~~~~~~~~~~~~~~~~~^^
  File "C:\Users\lenovo\Documents\GitHub\web dev\univers\src\univers\versions.py", line 87, in __attrs_post_init__

univers.versions.InvalidVersion: '10.0.2-10.1.0' is not a valid <class 'univers.versions.PypiVersion'>

it is expected in output.
@pombredanne what we expect in output, also this is happened due to

    @classmethod
    def build_value(cls, string):
        """
        Return a packaging.version.LegacyVersion or packaging.version.Version
        """
        return packaging_version.Version(string)

@pombredanne
can i change this buld_value to

    @classmethod
    def build_value(cls, string):
        """
        Return a packaging.version.LegacyVersion or packaging.version.Version
        """
        try:
            return packaging_version.Version(string)
        except packaging_version.InvalidVersion:
            return False

basically it simply return false when package version is invalid without tracebacks..
