Try adding this before installing Rasa X: brew install libxml2 libxmlsec1 pkg-config

Should this be done in the 'venv' where Rasa version is installed? (it is a different version from that outside the venv). Thanks

This solved the issue for me!

@uk_butterfly I believe brew install downloads packages for your Mac itself, so the command above can be run anywhere and this should work.
