No local packages or working download links found for python_version (thought it exists)

I am trying to install/setup this git repo: https://github.com/xiahongze/pdf_annot

I am getting this error:

> python setup.py install
:
:
Installed e:\work\projs\scraping\scan_pdfs\scanpdfs\lib\site-packages\pdf_annot-0.1.0-py3.7.egg

Reading https://pypi.org/simple/python_version/
No local packages or working download links found for python_version>=3.7
error: Could not find suitable distribution for Requirement.parse('python_version>=3.7')

My python version is:

> python --version
Python 3.7.6

Same issue happens with pip install. Is there a way to fix this?

Solution

It's is a bug in setup.py. This is how it must be written:

python_requires='>=3.7',
install_requires=[
    'PyMuPDF>=1.16'
],

Let's see. pdf-annot, the only release version 0.1 was in 2019. Not even a single bug report. The package seems unused, broken and abandoned.

You can try to send a pull request to fix it but I suspect it will be stuck. Perhaps the best course of action for you is to fork the repository, fix it and install from your fork.

PS. Well, there is a package python-version with a single release version 0.2. Certainly not a dependency for this package.
