Group,
I cannot get Neuron to run with this configuration. I get the following error:
loading membrane mechanisms from @executable_path/../../share/nrn/demo/release/x86_64/.libs/libnrnmech.so
Additional mechanisms from files
cabpump.mod cachan1.mod camchan.mod capump.mod invlfire.mod khhchan.mod mcna.mod nacaex.mod nachan.mod release.mod
ImportError: No module named site
neurondemo exit status was 1
Press return key to exit
Not sure how to proceed.
Thank you in advance.

This is due to an incomplete python installation. I'm wondering why python did not print the stacktrace that showed that the underlying problem is a missing
pyconfig.h file
You can avoid it by launching nrniv from a terminal window with the -Py_NoSiteFlag option. (the icons use /Applications/NEURON-7.3/nrn/x86_64/bin/nrngui
and you can change the last line from
Code: Select all
exec "$program" "$NEURONHOME/lib/hoc/nrngui.hoc" "$@" -
to
Code: Select all
exec "$program" =PY_NoSiteFlag "$NEURONHOME/lib/hoc/nrngui.hoc" "$@" -
Better yet, though, do you have a pyconfig.h file on your machine? If so where is it? Perhaps you have not yet installed the xcode command line tools.
You would certainly need that to process mod files.

I had already installed the developer tools. Still no go. I have not had this problem in the past. Neuron was always an easy install.
Not sure how to correct this. I am not a Python guy, I just setup and install for labs.
Sorry for the naiveté. :-)

I am also new to Neuron and had the same problem for several days now, although I tried to use the standalone version.
Today I found out that it was caused by an incompatibility of python 3.X.X with Neuron 7.3.
Uninstalling the python 3 framework via terminal and reinstalling python 2.6.8 (2.7.5 caused another error) fixed the problem.
I could imagine that it's the same problem with the new Canopy/EPD versions.
Cheers,
Matthias
