HowTo run GeoDjango and PostGIS on M1 macOS arm64 MacBook

geodjango_macOS_arm64.md

1. Install PostgreSQL with PostGIS via Postges.app
2. Install brew as recommended.
3. Install dependencies:

   brew install geos gdal
   

4. Add the following to your settings:

   # settings.py
   GDAL_LIBRARY_PATH = os.getenv('GDAL_LIBRARY_PATH')
   GEOS_LIBRARY_PATH = os.getenv('GEOS_LIBRARY_PATH')
   

5. Run Django with the following command, or set variables in your local enviornmeht:

   GDAL_LIBRARY_PATH=/opt/homebrew/lib/libgdal.dylib GEOS_LIBRARY_PATH=/opt/homebrew/lib/libgeos_c.dylib ./manage.py runserver
   

mach-o file, but is an incompatible architecture (have 'arm64', need 'x86_64')

I am actually getting this error. Tried brew gdal path and conda gdal. using M1 Pro mac, Python 3.8

Hi @imtipu, thanks for reaching out. It looks to me, you are running your terminal via Rosetta in x86_64-mode. You don't need that, and I wouldn't recommend to. You can get everything for arm64 these days via Homebrew. A quick uname -m should show you what architecture you are running.

Yet another approach ln -s /opt/homebrew/lib ~/lib

what is the solution even I tried arch -x86_64 /usr/local/homebrew/bin/brew install gdal but it failed to install gobject-introspection
