So I manually installed the missing python-bidi just to find out that psychopy crashes with the following exception:

18:41:04: Debug: Adding duplicate image handler for 'Windows bitmap file'
18:41:04: Debug: Adding duplicate image handler for 'Windows bitmap file'

    return getattr(self._module, name)

During handling of the above exception, another exception occurred:

I made sure to install everything wxWidgets-related to no avail. Any idea?

I was going to put a check into the PKGBUILD, but pytest for psychopy is pinned to <4.1 See: https://github.com/psychopy/psychopy/issues/2189

If you want to run all tests against the system dependencies installed through pacman I recommend:

git clone https://aur.archlinux.org/psychopy.git
cd psychopy
makepkg -o
cd src/psychopy-3.0.7
sudo pip install pytest==4.0.2
pytest -s -v psychopy

When running against system installed packages I get freetype issues. the AUR package for python-freetype-py is out of date, and I am waiting for it to be orphaned so I can take it.

After doing a manual update of python-freetype-py, the tests run, but there are a few fails. These occur when testing in a virtualenv as well; so at an initial glance it is looking like more of an upstream issue. I'll continue to investigate further, but if there are any issues on the arch package side, let me know.

While I can get the package to run and install just fine and psychopy seems to work once installed, the unit tests fail miserably. If I install python.pytest and run

py.test /usr/lib/python3.7/site-packages/psychopy/tests/

I get a whole bunch of errors ending in

AttributeError: module 'pytest' has no attribute 'app'

This happens in a clean chroot, a minimal environment running X, and my working system. I think it would be helpful if the package could pass the unit tests.

Thank you for the update. This is great. There is a small bug on line 49:

$psychopy.png should be $pkgname.png

Updated to 1.84.1. It now depends on python2-moivepy.

yes, I rebuild python2-imaging which failed with an error already reported there.
I was also able to build the package when removing the patch.
At the end of the installation it gave me a conflict with python2-pillow. I removed it, the installation finished, and psychopy was working afterwards (hope removing python2-pillow has no negative consequences...).

@psyxcience the first part of the output:

Warning: Mismatch between the program and library build versions detected.
The library used 3.0 (wchar_t,compiler with C++ ABI 1008,wx containers,compatible with 2.8),
and wxPython used 3.0 (wchar_t,compiler with C++ ABI 1002,wx containers,compatible with 2.8).

is just a warning from a check in wxGTK about a fairly harmless issue (https://bbs.archlinux.org/viewtopic.php?pid=1524176#p1524176). The second part of the output:

Speicherzugriffsfehler (Speicherabzug geschrieben)

which Google translates for me as: "(Written dump ) memory access error" seems problematic. I just rebuilt the package and tested in an i686 clean chroot and everything works fine for me. I am on a x86_64 system, so it is possible there is an issue with the kernel, but there is what I think is a bug in the python2-imaging PKGBUILD (https://aur.archlinux.org/packages/python2-imaging/) that may be causing the problem. Can you try rebuilding the python2-imaging package?

Hi. This is not working for me (4.2.3-1-ARCH i686 KDE & Openbox). It had been working a few months ago.
Installed "avbin7" and "python-pyo..." from AUR before psychopy.

When starting psychopy(App.py) the logo appears, then I can see the application for an eyeblink before it crashes. I get the following error:

Warning: Mismatch between the program and library build versions detected.
The library used 3.0 (wchar_t,compiler with C++ ABI 1008,wx containers,compatible with 2.8),
and wxPython used 3.0 (wchar_t,compiler with C++ ABI 1002,wx containers,compatible with 2.8).
Speicherzugriffsfehler (Speicherabzug geschrieben)

For anyone wondering, the binary is called "psychopyApp.py".

I am unable to get iohub working on my 64 bit machine. I am not sure if this is an issue with the package, Arch, or up stream.
