Hi,
I have multiple versions of each of various languages such as Python
or R. On the command line I can select a version using the 'module'[1]
mechanism provided by Lmod[2]:
module load Python/2.7.18-GCCcore-9.3.0
or
module load Python/3.8.6-GCCcore-10.2.0
This 'module' mechanism basically just provides a sane way to tweak and
untweak environment variables.
My question is: How do I change the environment, ideally call 'module
load ...' but potentially just set environment variables, before calling
a source block?
Cheers,
Loris
