ERROR in "from solidspy.solids_GUI import solids_auto"

Thank you providing a great project!
Here is an error when I try to import solids_auto:

Traceback (most recent call last):
File "", line 1, in
File "/Users/user/Library/Python/2.7/lib/python/site-packages/solidspy/init.py", line 3, in
from solidspy.solids_GUI import solids_GUI
File "/Users/user/Library/Python/2.7/lib/python/site-packages/solidspy/solids_GUI.py", line 25, in
import solidspy.preprocesor as pre
AttributeError: 'module' object has no attribute 'preprocesor'

How can I solve this issue?
Thank you in advance:)

It seems that you are using Python 2.7. But we dropped it last year with the end of support.

Thank you @nicoguaro for your reply.
I changed to Python3.7.6, but I have another error here:
libc++abi.dylib: terminating with uncaught exception of type NSException

Is there any other problem in my environment?

Thank you for your support.

I just realized that you seem to be using the development version. What was your setup process?

Thank you @nicoguaro for your reply.
I followed the instruction and run
pip install solidspy
pip install easygui
pip install meshio
My environment seems to be anaconda.

@koz7, I think I know what the problem is. You are installing the stable version (1.0.16) but the readme in GitHub is presenting an example for the developing version (2.x). I would suggest that you check the official documentation

https://solidspy.readthedocs.io/en/latest/readme.html

Try the steps there and let me know if it works.
