rigid package

Hi all
When I run the example code of DIFFUSE, I face with this error:
ERROR: Invalid fix style (…/modify.cpp:714)
I searched for reason and understood that it may be for lack of installation of rigid package. Now my question is that how I can see whether rigid package is installed on my pc or not?
Thanks for your help.

​any reasonably recent LAMMPS executable supports using the -help flag.
