Dependency clash: slugify

[AntoineAugusti]

Installing cookiecutter installs python-slugify which clashes with a udata dependency, awesome-slugify

Symptom

You'll encounter the following issue when starting your udata webserverser

  File "/Users/antoineaugusti/Documents/udata/udata/core/storages/api.py", line 10, in <module>
    from . import utils, chunks
  File "/Users/antoineaugusti/Documents/udata/udata/core/storages/utils.py", line 6, in <module>
    from slugify import Slugify
ImportError: cannot import name 'Slugify' from 'slugify' (/Users/antoineaugusti/Documents/udata/venv/lib/python3.7/site-packages/slugify/__init__.py)

Fix

You can force the reinstallation of awesome-slugify to use the required package on udata.

pip install --upgrade --force-reinstall awesome-slugify

python-slugify is only required when executing the cookiecutter command and not when running the app.

Indeed.

Never happened to me because cookiecutter is not installed in my udata's env:

$ which cookiecutter
/usr/local/bin/cookiecutter

I installed it in the same venv for commodity. If someone else does the same, at least the issue explains why they'll have an issue and how to fix it.
