Running collectstatic on server : AttributeError: 'PosixPath' object has no attribute 'startswith'

Question

After deploying on a server on digital ocean using nginx, gunicorn, django, and virtualenv, I try to use collectstatic:

python manage.py collectstatic --settings=config.settings.production

As you can see I have multiple setting files. One base, one local and one production setting file. Below is the error:

    Traceback (most recent call last):
  File "manage.py", line 22, in <module>

  File "/home/tony/vp/vpenv/lib/python3.5/posixpath.py", line 64, in isabs
    return s.startswith(sep)
AttributeError: 'PosixPath' object has no attribute 'startswith'

my production.py settings file contains the following:

MEDIA_ROOT = BASE_DIR / 'media'
MEDIA_URL = 'media/'
STATIC_ROOT = BASE_DIR / 'static'

my base dir is as follows (imported from the base setting file):

BASE_DIR = Path(__file__).resolve().parent.parent.parent

What could be the cause?

You're using Python 3.5. Support for Path objects in the os module was added in Python 3.6. You can:

• either upgrade to Python 3.6; or

• avoid using Path objects:

  BASE_DIR = os.path.abspath(os.path.join(__file__, '../../../'))
  MEDIA_ROOT = os.path.join(BASE_DIR, 'media')
  STATIC_ROOT = os.path.join(BASE_DIR, 'static')
