AttributeError: 'module' object has no attribute 'lru_cache' with python 3.6.4 and Django 2.0.2

[Greng Fortezza]

Hi,

I'm trying to set up the following configuration in Docker

python: 3.6.4

Django: 2.0.2

Apache/2.4.10 (Debian)

First, I was getting the error 

ImportError: No module named django.core.wsgi

Then I added Django to PYTHONPATH

export PYTHONPATH="/usr/local/lib/python3.6/site-packages"

the previous problem has gone away but now there is another one

AttributeError: 'module' object has no attribute 'lru_cache'

Apache configs contains the following line 

WSGIScriptAlias / /www/settings/wsgi.py

where /www/settings/wsgi.py is  actual path to wsgi.py file.

What could be wrong?

Thanks,

Greng

Hi,

Normally you shouldn't have to add site-packages in the PYTHONPATH since it is supposed to be already. If not, packages installed via "sudo pip install" would not be found.

I've packaged a lot of applications in Docker containers, and never had to modify PYTHONPATH.

Your problem is maybe be lurking elsewhere than PYTHONPATH, and this change has just created a new one which is hiding the original one, but not solving it at all.

Best

Eric

I’m not familiar with Docker, but I did have to add the path to Python 3.6 DLLs in my WSGI configuration in my Apache configuration file.

WSGIPythonPath ${project_path};${virtualenv};C:/Python36/DLLs;

Maybe it works like this in Windows (I don't know since having left this world since long now), but Greng mentioned a Debian environment inside his Docker container. Hence my remark.

By the way you mentioned "DLLs". Geng's trouble seems to be related to Python packages finding, not binary libs. In Linux, they are governed by different search paths.
