Really ?
Here is the traceback you posted before:

pyglet.gl.ContextException: Unable to share contexts
It tells that your prog started in run_game.py , which imports a module
main, then calls main.main() , which calls (cocos) director.init which
tries to instantiate a window trough pyglet window.Window which explodes
when it can't create an Open GL shared context.
No particles involved here.

When I try your suggestion I have the error:

This sounds as importing cocos particles before the window creation. Are
you sure the call to director.init is before your import of
cocos.particle_system ?
Can you post a short script that demostrates the problem ?
