I use the more comfortable way, keep the component within /home/user/... environment. Also good for backup of the configuration. In storage folder of component open terminal here, then:
sudo halcompile --install --userspace yourcomponent.py
sudo halcompile --install --userspace yourcomponent.py

To MaHa:
I tried your way, but it did not work.
I cannot use "sudo", because I have RIP instalation.

All info about is here and this worked for me:
linuxcnc.org/docs/stable/html/man/man1/halcompile.1.html
without root it might be difficult, but i don't know, as i have installed from .iso.

Did you set the RIP environment before running those commands?
Just a stab in the dark as i have not used RIP for over 5 years or more.

If I didn't use rip-environment, halrun wouldn't work.
I also didn't write that I use Debian Bookworm.
