问题
Im trying to use Django with Geodjango, I followed all documentation steps, but still got this error when trying to make migrations:
OSError: [WinError 127] : The specified procedure could not be found
The models.py is correct, I'm using from geodjango site, and this is my settings.py

OSError: [WinError 127] The specified procedure could not be found
I checked and all requeriments for geodjango are installed.
Any suggestions?
回答1:
You probably have multiple Python versions and there is conflict between them.
Try to install the GDAL on your virtualenv and ensure that the gdal202.dll is in your virtualenv context.
Also ensure that you installed the right compiled version from https://www.lfd.uci.edu/~gohlke/pythonlibs/#gdal, using pip and inside your virtualenv.
