Update moduleInit.R to check env for modulecmd #8

Closed warrenson closed 3 months ago

warrenson commented 4 months ago

Fail only if modulecmd is not in the installation tree and not on the PATH.

Motivation

In RHEL9, modulecmd is not contained within the installation tree at MODULESHOME/bin/modulecmd, but is on the PATH at /usr/bin/modulecmd.

It seems wrong to moduleInit(modulesHome='/usr' when MODULESHOME=/usr/share/modules, even though this works.

Solution

One possible solution is to test for modulecomd in the env if it is not found at MODULESHOME/bin/modulecmd.

Foreseen Consequences

Possible issues where the modulecmd binary and installation mismatch, when multiple installations of Environment Modules exist on the same system, depending on how PATH is managed.

This doesn't fix the issue, on further testing.
