PyOpenGL raises an exception after being frozen using cx_Freeze?

Question

I am making a game in PyOpenGL and want to freeze it using cx_Freeze. But it seems to me that importing PyOpenGL raises an exception in the PyOpenGL module.

from OpenGL.GL import *

When I run the frozen script:

Traceback (most recent call last):
  File "/Library/Frameworks/Python.framework/Versions/3.6/lib/python3.6/site-packages/cx_Freeze/initscripts/__startup__.py", line 14, in run
    module.run()
  File "/Library/Frameworks/Python.framework/Versions/3.6/lib/python3.6/site-packages/cx_Freeze/initscripts/Console.py", line 26, in run
    exec(code, m.__dict__)
  File "/Users/noah/Desktop/DesktopNoah/cx_freeze/PhW.py", line 5, in <module>
    from OpenGL.GL import *
  File "/Library/Frameworks/Python.framework/Versions/3.6/lib/python3.6/site-packages/OpenGL/GL/__init__.py", line 3, in <module>
    from OpenGL import error as _error
  File "/Library/Frameworks/Python.framework/Versions/3.6/lib/python3.6/site-packages/OpenGL/error.py", line 12, in <module>
    from OpenGL import platform, _configflags
  File "/Library/Frameworks/Python.framework/Versions/3.6/lib/python3.6/site-packages/OpenGL/platform/__init__.py", line 35, in <module>
    _load()
  File "/Library/Frameworks/Python.framework/Versions/3.6/lib/python3.6/site-packages/OpenGL/platform/__init__.py", line 29, in _load
    plugin = plugin_class()
TypeError: 'NoneType' object is not callable

How can I solve this issue and get PyOpenGL to work?

EDIT: For people who don't have PyOpenGL, the below function shows how it is working:

import os, sys
from OpenGL.plugins import PlatformPlugin
def _load( ):
    """Load the os.name plugin for the platform functionality"""
    key = (os.environ.get( 'PYOPENGL_PLATFORM'), sys.platform,os.name)
    plugin  = PlatformPlugin.match( key )
    plugin_class = plugin.load()
    plugin.loaded = True
    # create instance of this platform implementation
    plugin = plugin_class()

    # install into the platform module's namespace now
    plugin.install(globals())
    return plugin

_load()

And also the platform plugin function:

class PlatformPlugin( Plugin ):
    """Platform-level plugin registration"""
    registry = []
    @classmethod
    def match( cls, key ):
        """Determine what platform module to load

        key -- (sys.platform,os.name) key to load 
        """
        for possible in key:
            # prefer sys.platform, *then* os.name
            for plugin in cls.registry:
                if plugin.name == possible:
                    return plugin
        raise KeyError( """No platform plugin registered for %s"""%(key,))

Try to add "OpenGL" to the packages list of the build_exe_options in the setup.py script:

build_exe_options = {"packages": ["OpenGL"]}

# ...

setup(  name = ...,  # complete!
        ...
        options = {"build_exe": build_exe_options},
        executables = [Executable(...)])

See the cx_Freeze documentation for further details.
