As the administrator moved my account to another directory, gems refused to function. I modified the absolute path in env, the symbol link of ' $GEMS/Simics-2.2.19/src/extensions/' and paths in the checkpoint. Then I loaded the checkpoint successfully. However there was an error when I tried to load-module ruby, the error is:
Error loading module 'ruby' : Module 'ruby' not found
Please let me know what the problem is.
