tried fix from this answer : Unable to import opengl.gl in python on macos

content of site-packages/OpenGL/platform/ctypesloader.py file where error occurs is like this :

 if isinstance( dllType, ctypes.LibraryLoader ):
     dllType = dllType._dlltype
 fullName = '/System/Library/Frameworks/OpenGL.framework/OpenGL'#None this path was edited it was none before , LOCALCHANGES
 try:
     fullName = util.find_library( name )
     if fullName is not None:
         name = fullName
     elif os.path.isfile( os.path.join( DLL_DIRECTORY, name   '.dll' )):
         name = os.path.join( DLL_DIRECTORY, name   '.dll' )
 except Exception as err:
     _log.info( '''Failed on util.find_library( %r ): %s''', name, err )
     # Should the call fail, we just try to load the base filename...
     pass
 try:
     return dllType( name, mode )
 except Exception as err:
     err.args  = (name,fullName)
     raise

How to fix this?

CodePudding user response：

I think you were on the right track. You please change your below code:

 fullName = '/System/Library/Frameworks/OpenGL.framework/OpenGL'#None this path was edited it was none before , LOCALCHANGES
 try:
     fullName = util.find_library( name )

 fullName = None
 try:
     fullName = '/System/Library/Frameworks/OpenGL.framework/OpenGL'

Hope this will help you.
