Is this problem reproducible? If you reinstall EasyBuild v4.4.0, does
the problem stay?
I've done the bootstrap again now. The bootstrap log file is attached.
The log shows that the reinstall didn't actually happen:

You should remove the EasyBuild/4.4.0 module file, or set this before
re-bootstrapping:
export EASYBUILD_FORCE=1
I have the same problem:

ERROR: No compatible 'python' command found via $PATH (EasyBuild
requires Python 2.6+ or 3.5+)
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)

$ 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
