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. I have the same problem: [modules@d059 ~]$ eb --help >> Considering '/usr/bin/python3'...>> '/usr/bin/python3' version: 3.6.8, which matches Python 3 version requirement (>= 3.5) >> '/usr/bin/python3' is NOT able to import 'easybuild.main', so NOT retaining it

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=python3But 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 >> Considering '/usr/bin/python3'...>> '/usr/bin/python3' version: 3.6.8, which matches Python 3 version requirement (>= 3.5) >> '/usr/bin/python3' is NOT able to import 'easybuild.main', so NOT retaining it>> Considering 'python'... >> No 'python' found in $PATH, skipping... >> Considering 'python3'...>> 'python3' version: 3.6.8, which matches Python 3 version requirement (>= 3.5)>> 'python3' is NOT able to import 'easybuild.main', so NOT retaining it >> Considering 'python2'... >> No 'python2' found in $PATH, skipping...ERROR: No compatible 'python' command found via $PATH (EasyBuild requires Python 2.6+ or 3.5+)$ python3 -O -m easybuild.main Traceback (most recent call last): File "/usr/lib64/python3.6/runpy.py", line 193, in _run_module_as_main "__main__", mod_spec) File "/usr/lib64/python3.6/runpy.py", line 85, in _run_code exec(code, run_globals)File "/home/modules/software/EasyBuild/4.4.0/lib/python3.6/site-packages/easybuild/main.py", line 48, in <module> from easybuild.framework.easyblock import build_and_install_one, inject_checksums File "/home/modules/software/EasyBuild/4.4.0/lib/python3.6/site-packages/easybuild/framework/easyblock.py", line 54, in <module>import easybuild.tools.environment as envFile "/home/modules/software/EasyBuild/4.4.0/lib/python3.6/site-packages/easybuild/tools/environment.py", line 36, in <module>from easybuild.tools.config import build_optionFile "/home/modules/software/EasyBuild/4.4.0/lib/python3.6/site-packages/easybuild/tools/config.py", line 47, in <module>from easybuild.base.frozendict import FrozenDictKnownKeys ModuleNotFoundError: No module named 'easybuild.base.frozendict'On 04/06/2021 13:33, Ole Holm Nielsen wrote:I just installed EasyBuild v4.4.0 on a server running Almalinux 8.4: $ python3 bootstrap_eb.py $EASYBUILD_PREFIX Unfortunately, I'm now getting this error about a missing python: $ eb --helpERROR: No compatible 'python' command found via $PATH (EasyBuild requires Python 2.6+ or 3.5+)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?
