I have been migrating our geodjango application from Heroku to DO App platform. I have managed to get GDAL, GEOS, and PROJ installed via Aptfile and the wheels for gdal et al build.
The deployment fails on collecting static with the error that libblas.so.3 cannot be found. The build pack seems to be detecting the library paths and adding it to PATH. I am using the django.contrib.gi.db.backends.postgis as the database engine. The database is a development database in App platform.

You may need to update application code to resolve this error.
Or, you can disable collectstatic for this application:
$ heroku config:set DISABLE_COLLECTSTATIC=1

According to the apt-get output libblas3 should be installed as part of the gdal-bin apt-get installation.
Can anyone help me get this application up and running? Many thanks.

Hey!
This is quite interesting, is your project open-source by any chance? If so can you share a link to your GitHub repository so I could try deploying this on my end and further look into it?
As far as I can tell, it seems the libblas library is missing and even though it should be installed with
gdal-bin, it might not be in the right place. You could try adding it explicitly to your Aptfile:- Bobby
