I have the same problem!!

I've solved this problem by copying the libmpfr.so.6 to lib as libmpfr.so.4, and retry the command~
Best wishes!

please tell me where to find libmpfr.so.6 and the specific lib path, i use command: locate libmpfr.so.6, find it and i put it in anaconda3/envs/pointgroup/lib can not work and i put it in PointGroup(from github code)/lib and can't work too.
i already rename .so.6 to .so.4.
Thanks for your reply

Try to download mpfr again: conda install conda-forge::mpfr
