Closes #3805
I'm using Python 3.9. I tried
python setup.py sdist upload -r pypitestbut gotThe answer seems using
twineinstead, and from the link there callingsetup.pyshould be deprecated.So I use
buildandtwineto publish both source and wheel to test pypi.I also gave a try to Python 2, but
python -m buildgave error. I don't want to bother with that since Python 2 has reached EOL for 2 years and half. I think ANTLR should drop Python 2 support some time.
