So the conclusion that 'python3' doesn't give access to a working
EasyBuild installation was correct...
Your EasyBuild installation is basically broken, but the question then
is how this happened, since the bootstrap procedure includes a check to
ensure the installation completed correctly...
Do you have a 'base' subdirectory in
/home/modules/software/EasyBuild/4.4.0/lib/python3.6/site-packages/easybuild/,
and if so, what's in there?
Is this problem reproducible? If you reinstall EasyBuild v4.4.0, does
the problem stay?

Somehow that's resulting in a non-zero exit code, which makes the 'eb'
wrapper conclude it can't use the 'python3' command.
You can control which python* command is used to run EasyBuild using
the $EB_PYTHON environment variable:
export EB_PYTHON=python3
But that won't make any difference here, it should work already with
python3?
If you also define $EB_VERBOSE (any value, so "export EB_VERBOSE=1"),
you'll get a bit more information.
Indeed:
$ export EB_VERBOSE=1
$ eb --help

I just installed EasyBuild v4.4.0 on a server running Almalinux 8.4:

Obviously, Python3 is installed on this el8 system:
$ which python python3
/usr/bin/which: no python in
(/home/modules/software/EasyBuild/4.4.0/bin:/usr/local/bin:/usr/bin:/usr/local/sbin:/usr/sbin:/home/opt/modules/bin)
/usr/bin/python3
$ rpm -qf /usr/bin/python3
python36-3.6.8-2.module_el8.3.0+6191+6b4b10ec.x86_64
Is there a fix for the inability to locate the python command?
Thanks,
Ole
