Platform-specific instructions: Linux

All Linux distributions (recommended)

1. Use your distribution’s package manager to install

• Python or Python3
• pip or pip3
• build-essential (or equivalent)
• libffi-dev
• python-dev
• PortAudio

2. In a command line, run:

   sudo pip install -U pip
   sudo pip install -U expyriment[all]
   

   (Omit [all] to install without additional optional features; replace pip with pip3 when using Python 3)

For example, in Debian run:

sudo apt-get install python python-pip build-essential libffi-dev python-dev libportaudio2
sudo pip install -U pip
sudo pip install -U expyriment[optional]

Debian, Ubuntu and derivatives

We also provide Debian packages for Expyriment (python-expyriment). We suggest to install python-expyriment via NeuroDebian, a platform providing a large collection of neuroscience research software. For detailed instructions see: Installing Expyriment via Neurodebian

Note: If you have a previous version of Expyriment installed from source, please first uninstall the old version using the following command (replace X to match your Python version):

sudo rm /usr/local/lib/python2.X/dist-packages/expyriment

Notes

Switch off desktop effects, when running an experiment

Several window managers nowadays come with a compositing engine to produce 3D desktop effects. To get accurate timing of the visual stimulus presentation it is important to switch off desktop effects in your window manager!
