Error No such file or directory: 'gdal-config' when pushing app to heroku

Question

I've tried to push an app that contains geopandas to heroku and I get this error:

I've seen in this heroku post that you should add heroku's geo build pack. But if I do so, is like my app requirements.txt is no longer installed.

Here's what I get after adding heroku's geo build pack and removing BUILD_WITH_GEO_LIBRARIES like the post says you should:

He doesn't install pip requirements anymore. Can anyone help me on this?

Answer 1

I assume by your tags you're using python. If so, you're missing the python buildpack. Do on your gitbash or cmd:

heroku buildpacks:set heroku/python

Answer 2

Note that there is also a special geos heroku buildpack https://elements.heroku.com/buildpacks/heroku/heroku-geo-buildpack
