I tried to use environment modules (the module command), but it doesn't work.

  Some things to check:

  • Are using using setup in a batch script? This alias is normally only defined in interactive or login shells.

    The solution is to add the -l option to the shell invocation in the first line of your script; e.g., change

    #!/bin/bash
    to
    #!/bin/bash -l

    Be careful! If your login setup scripts do things that you don't want done in your batch scripts, use the -t 1 test to see if you're in an interactive environment; see the section on the less command below for more information.

  • If you're using tcsh as your shell, make sure you have the following command in your ~/.cshrc file:
    source /usr/nevis/adm/nevis-init.csh
    Or, if you're using an sh-style shell, make sure you have the following command in your ~/.profile file:
    source /usr/nevis/adm/nevis-init.sh
    If the initialization command is not there, then the system will not be able to find setup at all.

  • Are you using additional software (e.g., the LArSoft software framework) that also defines a setup command? If so, that command will override the Nevis version.

  • Are you using additional software (e.g., the LArSoft software framework) that uses the same packages (e.g., ROOT, Geant4) than the Nevis versions? If so, the software versions will likely conflict.
