pygame : 'NoneType' object has no attribute 'music'

Question

I'm currently making my first game in Python 3.5 with a friend for a school project. We are using pygame, and it was working fine until I change my computer for Ubuntu 16. I installed PyCharm. I could see that it was pointing that some things like pygame.init() were flaged as "Cannot find reference 'init' in '__init__.py'". I googled the message and it turned out it was a PyCharm bug with pygame.

But when I run my app, one of the warnings turns out not to be a bug : 'NoneType' object has no attribute 'music'. So Python doesn't find the mixer module for pygame, though I wrote import pygame in the concerned file :

    import pygame
....
    def play_music(self):
        pygame.mixer.music.load(<mymusic>)
        pygame.mixer.music.play()

Thank you for your help :)

-- EDIT -- I used print(pygame.mixer) to verify its value was None. I received :

<module 'pygame.mixer' from '/home/<myname>/.local/lib/python3.5/site-packages/pygame/mixer.cpython-35m-x86_64-linux-gnu.so'>

Maybe the `.mixer` is the problem? Can you print `pygame.mixer` and see if it outputs none? — Adam Hughes, May 25 '17 at 14:55
do you not need to set `pygame.mixer.music.load()` to a variable and just call `myvariable.play()` — tushortz, May 25 '17 at 15:02
The [docs](http://www.pygame.org/docs/ref/mixer.html#module-pygame.mixer) for `pygame.mixer` mention the following: "This module contains classes for loading Sound objects and controlling playback. **The mixer module is optional and depends on SDL_mixer. Your program should test that pygame.mixerpygame module for loading and playing sounds is available and intialized before using it**." — HEADLESS_0NE, May 25 '17 at 15:19
@CodingMouse do you have the SDL Mixer installed? If not, his is likely what is missing: https://www.libsdl.org/projects/SDL_mixer/ — HEADLESS_0NE, May 25 '17 at 15:22
