A guide for updating packages on PyPi

Sorry if i am replying too late but came across the same problem and found a way not to delete the existing dist folder:

after updating the version in setup.py and recreating the wheel file,

twine upload --skip-existing dist/*

will skip the distribution that already exist and upload the newer ones


I found out what my problem was - I did not delete the old files in the dist folder, so the uploader tried to upload them before the new files, and failed. The solution was to:

  1. Delete all files in the dist folder.

  2. Update the version number in the setup.py file.

  3. Re-create the wheels:

    python3 setup.py sdist bdist_wheel
    
  4. Re-upload the new files:

    twine upload dist/*
    

For Windows (I am on Windows 10), @Erel Segal-Halevi's answers doesn't work. Following worked for me.

c. Re-create the wheels:

py setup.py sdist bdist_wheel

d. Re-upload the new files:

py -m twine upload dist/*
