Hello I had this issue with installing Java-11. Java-11 installation isn't anything but to create a .modulerc file in which an alias for Java-11 is set. My installation faild with this error:

; stdout:
false
 (at easybuild/tools/modules.py:815 in run_module)

It is clear from the log file that my Lmod version was not sufficient despite that in the installation documents the recommended sufficient version is 6.5.1.

solution:

Update the Lmod to the latest version. I Updated That to 8.2.7 that worked for me.

proposal to address the issue:

Updating the Documentation will do the work.

I've moved this issue to the easybuild-framework repository, since the code generating the .modulerc is in easybuild/tools/module_generator.py.

Apparently Lmod 7.3 is not recent enough to parse the .modulerc file we generate.

The easiest way forward is hardening the version check, since in this particular case a sufficiently recent Lmod version is required. The version requirement mentioned in the documentation is for EasyBuild in general, but there are exceptions to that (this is one of those exceptions).
