DOC: Running it in virtualenv

[rvalyi]

Hello this not a bug report but a note how to run such an Odoo v16 project in virtualenv so it is not lost before we put it somewhere else.

This assumes you installed Postgresql and have it running on localhost with an odoo user with some_password.

python -m venv odoo
source odoo/bin/activate
pip install lxml==4.9.2  # this avoids ImportError: lxml.html.clean module is now a separate project lxml_html_clean
pip install -e odoo/src
odoo -s -c odoo-dev.conf --stop-after-init
# edit odoo-dev.conf, set db_host=localhost, db_user=odoo,db_password=some_password and put the result of ak build --links | sed 's#/odoo/#odoo/#g' into addons_path
odoo -c odoo-dev.conf
