Problems with "kspace_style pppm" used in triclinic box

Dear lammps users,

Now I’m trying to calculate the viscosity of water by sllod algorithm, which requires a triclinic box.
I use the “pair_style lj/cut/coul/long” to describe the SPC/E water model and it should be accompanied by the "kspace_style pppm " .
Then, I find there is a error "Cannot (yet) use PPPM with triclinic box (pppm.cpp:120) "
But, in the manual, it is stated that “The ewald/disp, ewald, pppm, and msm styles support non-orthogonal (triclinic symmetry) simulation boxes.”

So, why does this error occur? How can I calculate the viscosity of water?

I’m looking forward to having your help.

Best wishes

did you check the lammps version?

In other words, the current version has support for that,
for many months now.
