The Python Buildpack is showing a build warning that
BUILD_WITH_GEO_LIBRARIES is deprecated.
BUILD_WITH_GEO_LIBRARIES legacy feature has been deprecated. For the best experience, we encourage you to migrate to the third-party Heroku Geo Buildpack as soon as possible.
At the end of the six month deprecation period, as soon as Oct 6, 2020, support for
BUILD_WITH_GEO_LIBRARIES will be removed from the buildpack.
In order to continue to use the GDAL, GEOS and PROJ packages on Heroku, you can add the third-party Heroku Geo Buildpack to your application:
$ heroku buildpacks:add --index 1 https://github.com/heroku/heroku-geo-buildpack.git
Confirm that the buildpack has been added:
$ heroku buildpacks === Buildpack URLs 1. https://github.com/heroku/heroku-geo-buildpack.git 2. heroku/python
You will then need to remove the
BUILD_WITH_GEO_LIBRARIES environment variable from your application:
$ heroku config:unset BUILD_WITH_GEO_LIBRARIES
To ensure no issues on the new deploy, it is highly recommended to clear your cache.
