How to upload new versions of project to PyPI with twine?

Question

I\'ve uploaded my Python package to PyPI. But now I made new version of my package and need to upload it. I tried to make same progress which I did when upload the package first

Answer 1

PyPI does not allow for the reuse of distribution filenames (project name + version number + distribution type).

This ensures that a given distribution for a given release for a given project will always resolve to the same file, and cannot be surreptitiously changed one day by the projects maintainer or a malicious party (it can only be removed).

You will need to change the version number to one that you haven't previously uploaded to PyPI.

You didn't mention how you're uploading the distribution, but if you're using twine, it's also possible you're attempting to re-upload a previously uploaded distribution. To resolve this, you can do:

$ twine upload --skip-existing dist/*
