PIP Failure to satisfy dependencies that are listed as available

I am trying to restrict the range of acceptable versions of the ipykernel package when installing a project that has a pyproject.toml file requiring "setuptools>=45", and a setup.cfg file, which has the following as the install_requires option:

install_requires =
    nexusformat >= 0.7.5
    numpy
    scipy
    h5py >= 2.9
    qtpy
    qtconsole
    ipython
    ipykernel <= 6.8.0, >= 6.15.2

This triggers the following error message:

$ pip install -e .

ERROR: No matching distribution found for ipykernel<=6.8.0,>=6.15.2

In other words, the error message lists the versions that it claims it cannot match. It even happens when either ipykernel v6.8.0 or ipykernel v6.15.2 are already installed.

I have seen similar StackOverflow issues (e.g., here) but I don't see the same setuptools error even with verbose output. Is there a problem with setting discontiguous ranges? Or another syntax error? Any suggestions welcome.

I am running setuptools v65.3.0 and pip 22.2.2 in Python 3.8.

Unfortunately, what you're trying to achieve doesn't work with using the range specifiers because the use of < <= > >= (in pip, setuptools, etc.) are done with logical AND-ing rather than logical OR-ing. Efforts to improve this aspect have stagnated.

So for your needs:

I need to exclude versions between 6.9 and 6.15.1,

You'd have to instead exclude the versions you don't want, using the version exclusion specifier !=.

This line would suffice and excludes all releases of ipykernel between 6.9.* and 6.15.1.

ipykernel != 6.9.*, != 6.10.*, != 6.11.*, != 6.12.*, != 6.13.*, != 6.14.*, != 6.15.0, != 6.15.1

And you'll see that this works with installation under your circumstances...

# Done with fresh Python env, installs latest
> pip install "ipykernel != 6.9.*, != 6.10.*, != 6.11.*, != 6.12.*, != 6.13.*, != 6.14.*, != 6.15.0, != 6.15.1"

And try it with having an older ipykernel installed
