module command error

I am trying to port the cesm2.0.1 to a LINUX cluster.When I tried to run using ./case.submit,I got this message. module command /usr/bin/modulecmd python purge  failed with message:/bin/sh: /usr/bin/modulecmd: No such file or directory In cesm2.0.1/cime/config/cesm/machines/config_machines.xml,it is set as follows:          /usr/share/Modules/init/perl.pm      /usr/share/Modules/init/sh      /usr/share/Modules/init/csh      /usr/share/Modules/init/python.py      /usr/bin/modulecmd perl      /usr/bin/modulecmd python      module      module                      intel18/compiler-18         intel18/mvapich2-2.2
and case.submit (also .case.run) file is started in #!/usr/bin/env python.Even though /usr/bin/modulecmd exists, do you have any idea why I got the error message that "No such file or directory"?  

Hi there,I have met similar problems with you. Have you solved this problem? How? Any information is appreciated. Thanks a lot!Kind Regards,Huazhen

Dear Hauzhen,I'm not sure how my team solved this problem, but I guess modulecmd is needed for all nodes in your multiple nodes. At that time, main node in our server only had modulecmd, not for others.Best,Jin-Soo Kim

Dear Jin-Soo Kim,Thank you very much for your reply. I will check modulecmd again. Hopefully this problem can be solved soon. Thanks again.Kind Regards,Huazhen

Hi guys. I am working on CESM too. I am having the same problem when I try to run ./case.setup. How did you solve the problem?
