You install and run it differently since chirp-next is actually a python3 build.
I installed python3-pip, then as my user I installed chirp-next as my regular user using pip.
Will need to check my notes and verify the steps on a new clean install of
Fedora 37 and Chirp-next. (you did not note the OS you are running, but I assume it is linux.)
However, if you install it with pip as a regular user it is installed under /home/USER/.local/ and the executable is ~/.local/bin/chirp.
You will need to install (using pip) the wheel and wxpython and attrdict3 packages, but I don't remember what all else is required. This is why I need to repeat the clean install and verify my notes.
It runs in a venv if installed in that manner so nothing else is needed to run it. Check your $PATH and if it includes ~/.local/bin then the command 'chirp' is all that will be required.
