Can't install virtualenv

[davidcsi]

Hello all,

I'm on MACOS catalina, when trying to issue:

virtualenv --python=which python3 venv

I'm getting

Running virtualenv with interpreter /usr/bin/python3

TypeError: stat: path should be string, bytes, os.PathLike or integer, not NoneType

Already tried reinstalling virtualenv, i'm on

virtualenv --version 16.7.2

It's failing on

Are two filenames really pointing to the same file?

def samefile(f1, f2):
    """Test whether two pathnames reference the same actual file"""
    print("f1: %s" % f1)
    s1 = os.stat(f1)
    print("f2: %s" % f2)
    s2 = os.stat(f2)
    return samestat(s1, s2)

I put those prints there, i see first:

f1: /Applications/Xcode.app/Contents/Developer/usr/bin/python3
f2: /Users/david/Documents/vozelia/aws-codecommit/voice-infra-api/venv/bin/python3

but then

Any help is greatly appreciated!
