git: 'cz' is not a git command. See 'git --help'.

I don’t know how to deal with this.

I assumed it was simply a Path or symlink issue but got no where at all trying to understand how they work between bash, npm, git and commitizen.

I had to install commitizen as global npm package fot git cz to work.

If you don’t want to install commitizen globally you can write the write the hooks as follows:

exec < /dev/tty && node_modules/.bin/cz --hook || true
