ImportError: No module named PyMesh

问题

I have tried installing pymesh on both Mac OS and Windows, by downloading the source and installing using python setup.py install (as described in https://github.com/qnzhou/PyMesh).

In both cases, when I then ran the test code: python -c "import pymesh; pymesh.test()", I get an ImportError. E.g., in Windows, I get the following traceback:

Traceback (most recent call last):
File "<string>", line 1, in <module>
File "C:\Program Files\Anaconda2\lib\site-packages\pymesh2-0.1.14-py2.7-win-amd64.egg\pymesh\__init__.py", line 18, in <module>
from .Mesh import Mesh
File "C:\Program Files\Anaconda2\lib\site-packages\pymesh2-0.1.14-py2.7-win-amd64.egg\pymesh\Mesh.py", line 5, in <module>
import PyMesh
ImportError: No module named PyMesh

What is going on?

Ok, don't be worried. If you use the virtual environment to manage the python version. So you can solve this problem by the following:

cd $PYMESH_PATH
mkdir build
cd build
cmake -DPYTHON_LIBRARY=/Users/user/.pyenv/versions/anaconda3-5.2.0/lib/libpython3.6m.dylib -DPYTHON_INCLUDE_DIR=/Users/user/.pyenv/versions/anaconda3-5.2.0/include/python3.6m -DPYTHON_EXECUTABLE:FILEPATH=/Users/user/.pyenv/versions/anaconda3-5.2.0/bin/python ..
make -j
cd ..
python setup.py install

You can also refer to this.

This solved my problem.

Good Luck!!
