InvenTree: Error During Installation

Hello,

I’m trying to deploy Inventree. I’d followed all steps from here: https://inventree.readthedocs.io/en/latest/start/install/ and it give me that error when doing: invoke update

Traceback (most recent call last):
  File "/mnt/disk/inventree/src/InvenTree/manage.py", line 23, in <module>
    execute_from_command_line(sys.argv)
  File "/mnt/disk/inventree/env/lib/python3.10/site-packages/django/core/management/__init__.py", line 419, in execute_from_command_line

    raise FileNotFoundError('INVENTREE_STATIC_ROOT not specified')
FileNotFoundError: INVENTREE_STATIC_ROOT not specified

What I need to do to make it work?

Thank-you,

Guillaume
