I did git clone https://github.com/widdowquinn/find_differential_primers

    Merge pull request #56 from nick-youngblut/diagnostic_primers

    added ArgumentDefaultsHelpFormatter to all parsers; post-hoc changes to keep to project style (PEP8) by LP.

commit cb830b4d83263a414440c727670cf32247959be2

I did conda install --file requirements.txt -y and conda install --file requirements-thirdparty-primer3_237.txt -y with no problems. Then I did python3 setup.py install --prefix ~.

This installed into my ~/bin/

ls ~/bin

delta_filter_wrapper.py  f2py  f2py3  f2py3.10  pdp  pdp.py  pdp_mafft_wrapper.py  tqdm

All good so far. But when I try to execute ~/bin/pdp I get this:

~/bin/pdp --help

importlib.metadata.PackageNotFoundError: No package metadata was found for diagnostic-primers

Any ideas what's gone wrong? I could not find installation instructions for this version of pdp/find_differential_primers, only for the stable version.
