Issues when launching experiment from command line

alecristia

Dear all, thank you in advance for any help!

I solved this initial issue, but leaving the discussion open in case others run into the same problem.

I created an experiment which runs fine from the OpenSesame GUI, and now I'd like to launch it from the terminal using the code on this post. I get the error:
File "/anaconda/lib/python2.7/site-packages/openexp/_canvas/xpyriment.py", line 30, in
u'Failed to import expyriment, probably because it is not (correctly) installed. For installation instructions, please visit http://www.expyriment.org/.')
However, when I $ pip install expyriment[all]
Requirement already satisfied: expyriment[all] in /anaconda/lib/python2.7/site-packages

Notes:
Running on MacOS High Sierra, in case that is of any use. The end goal is to be able to dispense with the hand-loaded file pool, since we have 100 different conditions, each requiring a different set of wav files to be played. Thus, ideally, I'd run a script that selects from a condition that has not been ran, lists the wavs into a csv, and passes the participant number to the OpenSesame experiment, which relies on that newly created csv file list.

I also checked that the path to expyriment was in my system path:
import sys
print(sys.path)

yields a list that includes: '/anaconda/lib/python2.7/site-packages',

So then I launched expyriment directly, which revealed the real culprit: UTF-8 locale not recognized. The fix is here: https://coderwall.com/p/-k_93g/mac-os-x-valueerror-unknown-locale-utf-8-in-python

Although now the experiment starts to launch (e.g., a window appears ever so briefly), the error traceback doesn't allow me to know where the new issue is coming from:

Some of it appears to relate to fonts, but I can clearly see in the .osexp file that font HAS been specified:
set font_underline no
set font_size 26
set font_italic no
set font_family sans
set font_bold no
