After another go at this, I successfully installed PsychoPy 3 on Ubuntu Linux 16.04. It was surprisingly straightforward:
- Clone latest release from github. Open a terminal and at the command line enter
git clone https://github.com/psychopy/psychopy.git
This downloads psychopy files to a folder somewhere
- Use pip to install psychopy on your system. In the parent folder containing the downloaded files. at the command line enter:
pip install psychopy/
- Launch by entering
psychopy
at the command line. Worked out of the box for me, but maybe because I had already installed dependencies (see below)
