[ERROR] Problem occurred while building package pyyaml: Unresolved install path.

Hey there, I try to install gnuradio with pybombs. But I always get error: [ERROR] Problem occurred while building package pyyaml:
Unresolved install path.
Despite that I installed python-yaml/pyyaml.

My OS is Linux Manjaro 21.2.1
Here is my whole output
output.txt

And here a stripped-down version

[gnuradio@gnuradio-virtualbox ~]$ pybombs -v prefix init ~/Apps/gnuradio3 -R gnuradio-default
