Removing xblock does not uninstall

I have added my demo xblock (which was having error for testing purposes) in config.yml using OPENEDX_EXTRA_PIP_REQUIREMENTS, tutor config save and then rebuilt the image tutor images build openedx. Later I have to remove this xblock so I simply removed OPENEDX_EXTRA_PIP_REQUIREMENTS from config.yml, saved the config and rebuilt image, but I have seen that its presence is still in docker as the error is still appearing in log files.

How to remove its presence?

hi,

You can try to delete the old images, build new imagen and then run local tutor quickstart -I
and maybe it will work for you

Any idea how to delete old docker images?

docker image prune
