Error installation in ckan 2.9 with docker

[aantilao]

Hi,
I was trying to install spatial extension, specially spatial_metadata and spatial_query on my docker, but when i did the step on documentation y got this error. I do different step, for example y change the version of pip-requirements.txt and requirements.txt.
I got this error when I try to initialize the database (ckan --config=/etc/ckan/production.ini spatial initdb 4326) or if i put spatial_metadata and spatial_query on plugins (production.ini).

Has anyone else had this error, so they can help me
