Error when running python manage.py collectstatic

[Henrik Sejersen]

Hi



I get an error when running python manage.py collectstatic. The error is a
SuspiciousFileOperation exception because “The final path must be the same
as the base path”.

The strange thing is that I only get this error when my python version is
3.7.1. I do not get the error, if I change the standard interpreter version
to 3.6.5 with the exact same dependencies? I am using Django 2.1.3. The
method responsible for the exception appears only to be called when using
python 3.7.1. Here is the stack (I have added print of the local variables
base, base_path, and final_path inside the safe_join method):



(oekonomistyring) P:\python\odk\oekonomistyring>python manage.py
collectstatic

This is base: P:\python\odk\oekonomistyring\collectstatic\

This is base_path: P:\python\odk\oekonomistyring\collectstatic\

This is final_path: P:\python\odk\oekonomistyring\collectstatic\

This is base: P:\python\odk\oekonomistyring\collectstatic\

This is base_path: P:\python\odk\oekonomistyring\collectstatic\

This is final_path: P:\python\odk\oekonomistyring\collectstatic\



You have requested to collect static files at the destination

location as specified in your settings:



P:\python\odk\oekonomistyring\collectstatic\



This will overwrite existing files!

Are you sure you want to do this?



Type 'yes' to continue, or 'no' to cancel: yes

I suspect this might be a regression with 3.7. Can you confirm this also
exists with latest django 2.0.x version?

You can also make a bug report at https://code.djangoproject.com/query

Hi Jason

Yes, I get the same error with Django 2.0.9 (the latest version) and Python
3.7.1 - I am just about to make a bug report. Thanks!

I suspect this is not an issue with django itself, but rather the python
language runtime on windows

https://bugs.python.org/issue31047#msg328322

It'll be included in the next python patch release, I suspect.
