I will post the error below. I did the main django tuturoials on the website without a problem. But something happens when I change my ENGINE in settings.py to the postgis version.

This is the tutorial: https://docs.djangoproject.com/en/2.0/ref/contrib/gis/tutorial/#setting-up

It might be the way I have everything installed. It took me awhile to set up my PATH so that I could even use the ogrinfo tool.

This is what my DATABASES looks like in the settings.py:

'default': {
   'ENGINE': 'django.contrib.gis.db.backends.postgis',
    'NAME': 'djangogeo',
    'USER': 'postgres',
    'PASSWORD': '--------',
    'HOST': 'localhost',
    'PORT': '5432',}

Yes the database has been built and the postgis extensions have been applied.

The error message I am about to post shows up whether I use python manage.py runserver or python manage.py make migrations.

I am not sure what to really do at this point.

OSError: [WinError 193] %1 is not a valid Win32 application

Could it be some of my environment settings? I used this to fix my path problems earlier https://gisforthought.com/setting-up-your-gdal-and-ogr-environmental-variables/

After failing multiple times I decided to try this tutorial and started from the beginning and now it is happening again. I can't get past the 16:00 minute mark. Please help?

    I've seen this "%1 is not a valid Win32 application" error before while accidentally mixing 32-bit and 64-bit components. Check your OS and each components you installed to ensure it's all 64-bit or 32-bit. – Mike T May 6 '18 at 23:39
  • The python is 32 bit I believe. I know for sure the OSGeo package is 64.... Is there a 64bit python I should be using? thanks – Petey May 6 '18 at 23:42
  • Please Edit the question to add details. Comments are generally reserved for requesting clarification, not giving it. Please take the Tour , which explains how GIS SE works. – Vince May 7 '18 at 1:44
