ERROR: Unknown improper style

Dear I am trying to simulate a system, but I am getting an error :
ERROR: Unknown improper style (../force.cpp:600)
I checked the manual and I found out that such improper style can only
work with USER-NISC packages. I installed Lammps via HOMEBREW and I
checked the USER-MISC packages in my machine, it is installed and
enabled, so could you help me out to resolve issue ? Kindly check the
error below
