[Santhosh Kumar V V .]

Hi, I am trying to install nmigen and I get these error messages.

Traceback (most recent call last):
  File "setup.py", line 60, in <module>
    "Documentation": "https://nmigen.info/nmigen/{}".format(doc_version()),
  File "setup.py", line 23, in doc_version
    git = parse_git(".")
  File

line 195, in meta
    assert parsed_version is not None, "Can't parse version %s" % tag
AssertionError: Can't parse version working2

Is there any solution for this?
