setup.cfg declaring console_scripts errors with "Entry points must be listed in groups"

Question

I'm trying to configure setuptools to create a console entry point for my package, following the docs, and ending up with the following config:

[options.entry_points]
console_scripts = 
    hiplog = hiplog.scripts.hiplog:cli

But when I pip install -e . in my repository, pip raises the following error:

ERROR: Exception:
Traceback (most recent call last):
  File "/home/taschan/.pyenv/versions/3.9.0/envs/hiplog/lib/python3.9/site-packages/pip/_vendor/pkg_resources/__init__.py", line 2857, in get_entry_map
    ep_map = self._ep_map

    raise AttributeError(attr)
AttributeError: _ep_map

During handling of the above exception, another exception occurred:

    raise ValueError("Entry points must be listed in groups")
ValueError: Entry points must be listed in groups

What am I doing wrong?

Answer 1

I ran into this same symptom, and the root cause turned out to be a botched pip install -e . from a previous run. Deleting the projectname.egg-info directory did the trick.
