Import Errror for python pg module

I am having trouble using the pg module in my code. I've installed it using pip. But when I go to run it I get the following error:

Traceback (most recent call last):
  File "Contract_gen.py", line 2, in <module>
    import pg
  File "C:\Python27\lib\site-packages\pg\__init__.py", line 1, in <module>
    from .core import (
  File "C:\Python27\lib\site-packages\pg\core.py", line 6, in <module> 
    from . import glfw
  File "C:\Python27\lib\site-packages\pg\glfw.py", line 140, in <module>
    raise ImportError("Failed to load GLFW3 shared library.")
ImportError: Failed to load GLFW3 shared library.

How to solve for windows:

  1. Download Windows pre-compiled binaries from https://www.glfw.org/download.html
  2. copy (and replace) the file lib-mingw-w64\glfw3.dll to ...\Python27\Lib\site-packages\glfw\glfw3.dll
  3. Done

For me, glfw was working fine until one morning when it suddenly wasn't. This solution worked for me. I don't know if this is the correct way to solve it but it worked for me.

Your version of OpenGL might be too old compared to the pg requirement which is 3.1.0 as specified in https://github.com/fogleman/pg/blob/master/requirements.txt

You can re install python-openGL with pip:

$ pip install PyOpenGL PyOpenGL_accelerate

This removes this problem but creates other errors for me.

note, besides, that this problem seems to be mentioned in https://github.com/fogleman/pg/issues

It seems like to require the GLFW3 library. Download & install it and the error should be gone. If you use macOS you can get it via brew.
