Python 3 pip installation failing

[zmunro]

I have tried running installation with python3.6, 3.7, and 3.8 and I get a similar error message with each:

$ python3.6 -m pip install pymummer
Collecting pymummer

    Cannot install because some programs from the MUMer package not found.

Command "python setup.py egg_info" failed with error code 1 in /tmp/pip-build-ha4k5x9b/pymummer

Is there a fix for this available?

I don't know if this has changed, but the programs are now named (as of mummer 4.0rc1) mummer-nucmer, mummer-show-coords, etc. So, in setup.py, you need you change

required_progs = ['nucmer', 'show-coords', 'show-snps', 'delta-filter']

with this

required_progs = ['mummer-nucmer', 'mummer-show-coords', 'mummer-show-snps', 'mummer-delta-filter']

Now python setup.py test should say it did detect mummer, and can be installed.
