Hi, I'm trying to set up an Eriksen Flanker experiment (is all new to me!) and I can get aliens working with Pygame 2.0 but if I try to install Pygame v2.0 with v0.10 of Expyriment it uninstalls Experiment, then when I re-install Experiment it uninstalls v1.9 of Pygame. If I use Pygame 1.9 I get a screen freeze/hang even if I just try to run the test suite expyriment.control.run_test_suite() Any assistance would appreciated - please put me out of my misery :)

Are you on MacOSX? Could you tell us if the following instructions solve the issue or not? (installing pygame2 should not uninstall expyriment)

Install XQuartz. Download the .dmg from the official website and open it to install.
Open a Terminal and type pip install expyriment[all]
In the same Terminal, type pip install -U pygame

This upgrade the version of pygame (1.9) installed along expyriment to pygame (2.0), which is required by recent versions of macOS. (As of 2021-02-23.)

Hi - thanks for coming back to me so quickly - still having trouble - details below - I'm on Mac OS Big Sur ... can install pip but doesn't make any difference - also neither recognises the [All] parameter or any specific ones either - I've been back through the instructions and can't find what is wrong.

Thanks again!

The message is fine (uninstalling pygame 1.96). The question is: what happens now when you run expyriment scripts? Do they work or not?

Glad to hear you made Expyriment work with Pygame 2. But please also keep in mind that the current Expyriment version does not officially support Pygame 2 yet.

Best,

Florian
