Did someone test module installation in editable mode ?
Installation is working but when launching ./.venv/trytond/bin/trytond-admin -c../.trytond.conf -d mr_3009 -v --all --activate-dependencies

I’m getting this error:

There’s a file with path _saluc_tampography.pth in my .venv/lib/python/site_packages/
with correct path to my module.

Using editable mode without sub-directory for the module is tricky.
The simplest way is to use a fresh layout created using cookiecutter with a prefix. It creates the necessary symlinks to make it works.
