Linux mint install issue - no launch

BaaBob

Hi,
I've started moving over to a linux mint system, and ran into an issue trying to install OpenSesame. It seems to install with no trouble following the instructions on the site, but the program quits immediately on launch. Here is the output if I try to launch from the terminal:

Any idea what's causing the crash?

Hi again. OpenSesame runs in debug mode. Recurring error when playing around with it in this way is "ImportError: No module named PIL". I hope I'm getting closer to the root of the problem, but still no idea how to fix it.

BaaBob

Installed python PIL and related via package manager, now crashes on open in debug mode too.

So, it turns out I had to install a bunch of python modules and packages one by one. Maybe it's where the difference is among different operating systems, but I don't remember having to do that on windows (10) or mac os. I've now successfully run a couple basic experiments with text forms.

Hi BaaBob,

Good to hear that you figured it out. It sounds like this was a distribution-specific problem with installing the right dependencies, so it's hard to say anything about it. Thanks for reporting it though, and I'll keep an eye out for similar things should they come up again.

Cheers!

it seems there is a small difference between mint and ubuntu

i solved this by installing several Python packages:

pip install wheel

pip install sip PyQt5

pip install setuptools

pip install ipykernel==4.6.1 qtconsole

pip install image

pip install expyriment
