How to install psychopy on lab desktop

In python 2, execute the following commands in terminal (see this webpage for the source: http://neuro.debian.net/):

• wget -O- http://neuro.debian.net/lists/xenial.us-ca.full | sudo tee /etc/apt/sources.list.d/neurodebian.sources.list

• sudo apt-key adv --recv-keys --keyserver hkp://pool.sks-keyservers.net:80 0xA5D32F012649A5A9

Then, type:

• sudo apt-get update

• sudo apt-get install psychopy

Using this technique, there is a typo in the following file: '/usr/lib/python2.7/dist-packages/psychopy/hardware/joystick/init.py' that was not corrected by neurodebian/psychopy.

In a text editor, navigate to the try/except statement where it tests whether pygame is installed:

try:
    import pygame.joystick
    havePygame = True
except Exception:
    havePygame = False

Right above this try/except statement in our installed init.py file is a command to import pygame...before the try/except statement! Remove this line and everything _should _work!
