libmolgrid install error

[croshong]

I'm trying to install libmolgrid in fresh environment
after typing cmake
when I type make, I got following error

[ 60%] Building CXX object python/CMakeFiles/molgrid.dir/bindings_grids.cpp.o

npy_hash_t hash;

npy_half

the OS environment is following
OS : ubuntu 16.04
gcc : 8.4.0
python : 3.9.16

How can I solve this problem?

Python.h should include pyhash.h which defines Py_hash_t. You need to figure out what Python.h is being included instead of the correct one and direct cmake to the correct one.
