HG-Git: AttributeError: 'bytes' object has no attribute 'encode'

问题

I'm trying to clone a git repository with mercurial and hg-git, but an AttributeError keeps coming up. When I run hg clone git://github.com/michaelfm1211/simpleserve, the output I get is this:

AttributeError: 'bytes' object has no attribute 'encode'

I have no idea why this is happening. I've installed Mercurial with brew install hg and hg-git with ~/brew/opt/python@3.8/bin/easy_install-3.8 hg-git, because I've configured Homebrew to install to ~/brew instead of /usr/local.

AttributeError: 'bytes' object has no attribute 'encode'

Check first your python version used for Mercurial.

~/brew/opt/python@3.8 means probably Python 3.

However: This hg-git thread mentions:

hg-git does not work yet on Python3, but support may be coming soon.

hg-git can’t run that far on Python 3 and I suspect that you’re actually running Mercurial on Python 2.

See hg-git issue 298.
