[SOLVED] Asciidoctor / asciidoc not found in $PATH

There are 5 different ways - which one it is?
You did the distro repo way - yes? One of:

sudo apt-get install asciidoctor
sudo yum install asciidoctor
sudo dnf install asciidoctor

You show your $PATH - but not if asciidoctor actually is within the $PATH.
You get something like this?

$ which asciidoctor 
/usr/bin/asciidoctor
