Update, after an extensive search of my environment, I have found a hidden
directory that I can't access called
Weewx/bin.20200217183229/pip/_internal/utils which contains a file
packaging.py
This is the only file in my environment that contains the string NoneType
and when I edit this file I find the following and have posted the entire
function in case this means something to a Python coder
def get_metadata(dist):
# type: (Distribution) -> Message
"""
:raises NoneMetadataError: if the distribution reports `has_metadata()`
True but `get_metadata()` returns None.
"""
metadata_name = 'METADATA'
if (isinstance(dist, pkg_resources.DistInfoDistribution) and
dist.has_metadata(metadata_name)):
metadata = dist.get_metadata(metadata_name)
elif dist.has_metadata('PKG-INFO'):
metadata_name = 'PKG-INFO'
metadata = dist.get_metadata(metadata_name)
else:
logger.warning("No metadata found in %s",
display_path(dist.location))
metadata = ''
if metadata is None:
raise NoneMetadataError(dist, metadata_name)
feed_parser = FeedParser()
# The following line errors out if with a "NoneType" TypeError if
# passed metadata=None.
feed_parser.feed(metadata)
return feed_parser.close()
