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 time.
but give me this error:
HTTPError: 400 Client Error: File already exists. See https://pypi.org/help/#file-name-reuse for url: https://upload.pypi.org/legacy
Now, how to upload new version without any error?!
Answers:
You need to change the version number.
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/*
Can get that error for following reasons:
- Didn’t change your version in
setup.py
- didn’t remove your previous dist file
Solution:
- Change the version number in
setup.py
.
- Run setup file again.
python setup.py bdist_wheel
.
- Upload only that dist file or run twine (if using).
twine upload --skip-existing dist/*
As mentioned by @dustin, dist file of same name cannot be uploaded again.
Make sure your dist directory is empty before running
python setup.py sdist
The error seems to stem from the command:
twine upload --repository-url https://test.pypi.org/legacy/ dist/*
reusing the previous package version.
To fix this, try this:
twine upload --skip-existing --repository-url https://test.pypi.org/legacy/
dist/*
Another way that nobody mentioned is to provide an explicit filename:
twine upload --repository testpypi --skip-existing dist/myProject-0.1.9-py3-none-any.whl
This has advantages compared to the other proposed solutions, and precisely:
- while updating version number is a requirement for twine to upload the package, this doesn’t prevent the program to upload everything that is the
dist
folder, included previously uploaded versions. It’s ok if you move out the old versions, but I am not sure about possible implications.
- using
--skip-existing
option solves the above problem, but all files are still processed, so it takes time.
I am sure there are more efficient solutions, but this is simple enough for me.
