PIP install "error: package directory 'X' does not exist"

Question

I am trying to install this package via PIP. It gives me the following error:

error: package directory 'RTbatch' does not exist

I find this weird, because the relevant setup.py does not mention any packages variable, but only py_modules.

What's wrong? Can you help me out?

Here is the full output of pip install -e RTbatch:

Answer 1

py_modules takes a list of module names, not files. Your call looks for RTBatch/py.py and RTBatch_cli/py.py.
