I this sample I install cvgenpy first in iris.script and then shvarov-user-management as a dependency. Then trying to call a method via Invoke tag in module.xml causes an error as python modules from shvarov-user-management not installed. also you can notice Error messages on csvgenpy installation that state that there is a dependency conflict:
ERROR: pip's dependency resolver does not currently take into account all the packages that are installed. This behaviour is the source of the following dependency conflicts.
So, changing line i Dockerfile
RUN wget https://pm.community.intersystems.com/packages/zpm/0.10.4/installer -O /tmp/zpm.xml
to
RUN wget https://pm.community.intersystems.com/packages/zpm/0.9.2/installer -O /tmp/zpm.xml
solves the issue and everything works fine. a
