Hello!
I tried to install many extensions with composer, but a few times I ran into a few issues, this one is about the requirement of composer v1.
Many other extensions depend on composer v2, so installing them together is not possible.
This can be changed like in this commit in a fork of mine: htt ps://github .com/markus-96/mediawiki-extensions-UserFunctions/commit/06fec0c8fb3e27650c10731b00efe8f321791d82
Or like this: htt ps://gerrit.wikimedia. org/r/c/mediawiki/extensions/PageForms/+/942478/
That resolves the same issue in the PageForms extension: htt ps://phabricator. wikimedia.org/T340818
