No module named 'encodings'

Hello,

I tried to execute the python script by Catalyst, but I got this error message, could you provide some ideas to solve it? Thanks for your help!

Could not find platform independent libraries <prefix>
Could not find platform dependent libraries <exec_prefix>
Consider setting $PYTHONHOME to <prefix>[:<exec_prefix>]
Fatal Python error: initfsencoding: Unable to get the locale encoding
