Could not inherit file classes/python_hatchling.bbclass

[cppcoffee]

I follow the readme tutorial to configure the environment:

$ git clone https://github.com/openembedded/openembedded-core.git
$ cd openembedded-core
$ git clone https://github.com/openembedded/meta-openembedded.git
$ git clone https://github.com/openembedded/bitbake.git
$ git clone https://github.com/kraj/meta-openwrt.git
$ ../oe-init-build-env
$ bitbake-layers add-layer ../meta-openembedded/meta-oe
$ bitbake-layers add-layer ../meta-openembedded/meta-python
$ bitbake-layers add-layer ../meta-openembedded/meta-networking
$ bitbake-layers add-layer ../meta-openwrt

edit the ./conf/local.conf, Add the following:

INHERIT += " openwrt-distro-defaults "

run build

$ TCLIBC=musl MACHINE=qemuarm bitbake openwrt-image-minimal

after running, an error message is output. how can I fix it?

$ bitbake-layers show-layers
