Can't install Django-shop on Mac OS

Hello all,

I’m having an issue installing a fresh copy of Django-shop in a new pipenv environment in Pycharm. I’m following the instructions on the Django-shop website and the issue occurs at the pipenv install --sequential step (see terminal output below)

I’ve done this a few times over the last few weeks but this is the first time I’ve encountered this issue. I’m using Django 3.1.6 and Python 3.8.2.

Courtesy Notice: Pipenv found itself running within a virtual environment, so it will automatically use that environment, instead of creating its own for any project. You can set PIPENV_IGNORE_VIRTUALENVS=1 to force pipenv to ignore that environment and create its own instead. You can set PIPENV_VERBOSITY=-1 to suppress this warning.

It looks like an issue with versions of django-filer newer than 2.0.2. I was able to bypass the filer.admin.folderadmin.FolderAdmin class issue by declaring django-filer==2.0.2 in cookiecutter-django-shop/{{cookiecutter.project_slug}}/Pipfile.

I also enabled django-compressor, i.e. answered “y” to “use_compressor” question when executing “cookiecutter …”.

For those of you that don’t want to fork and modify the Pipfile yourself, you can use my fork. Just execute:

cookiecutter https://github.com/chandave/cookiecutter-django-shop

and answer “y” for the “use compressor” question.

interesting; reading around the issue reported by @ay0000 , I found one suggested workaround; the following indeed works: $ pipenv install --sequential --skip-lock

, but check reports two errors (same root cause, apparently):

ERRORS:
<class 'filer.admin.folderadmin.FolderAdmin'>: (admin.E039) An admin for model "User" has to be registered to be referenced by FolderAdmin.autocomplete_fields.
<class 'filer.admin.permissionadmin.PermissionAdmin'>: (admin.E039) An admin for model "User" has to be registered to be referenced by PermissionAdmin.autocomplete_fields.

System check identified 2 issues (1 silenced).
