Twine upload TypeError: expected string or bytes-like object

Question

Has anybody got an error like this when you try to upload your package ?

   $ twine upload dist/*
   Uploading distributions to https://upload.pypi.org/legacy/
   Enter your username: MyUsername
   Enter your password: ********
   TypeError: expected string or bytes-like object

Edit: Got the same error again but this time to fix it I upgraded twine and it started working again.

I have Uploading distributions to https://upload.pypi.org/legacy/ - TypeError: expected string or buffer right now... – Shit

Updating twine did solve the issue for me (problem showed up with 1.9.1 version; just upgraded to 1.11.0). – Fulguration

Answer 1

Updating twine solved the problem for me. For this, execute the following command before doing twine upload dist/*:

python3 -m pip install --user --upgrade twine

I'm guessing your response is a command that updates twine. Since that resolved the problem for me, I'm flagging your response as the accepted answer to help other users see it. – Pythoness

That's correct. I edited the text accordingly to make this more clear. – Triad

Answer 2

I had the same problem after installing twine by apt. It seems that it installed twine for python2 and my project was python3.

So I've installed twine with pip for python3:

pip3 install twine

and used the following command:

python3 -m twine upload dist/*

Worked perfectly fine
