Abort trap: 6 when running a python script

Question

I am working on a python program that displays an animation, thus I am using pyglet. Until now I've been working with the python compiler that comes with Psychopy, but now I need to make this program as most independent as possible.

I have achieved this task with a Windows machine, in the case of OSX, I have followed this post in order to install pyglet. However, when I now run the program, it returns this:

libc++abi.dylib: terminating with uncaught exception of type NSException
Abort trap: 6

I do not understand what this error means, can anyone help me understand what have I done wrong?

I have found the reason why this error appears. It is because I use the library TKinter, if I comment out the lines where I use TKinter, this error does not appear. However, the animation which I expected and works on Windows, does not appear, it only appears a black window. — jl.da, Jun 18 '14 at 15:16
I think it would be great to update the main question with this info and close this question. Then people know what to do if they run into it. Regarding the animation not working, you could post a new question on that specifically, of course posting a short code which replicates the error (works on Windows but not on mac). — Jonas Lindeløv, Jun 18 '14 at 17:40

I faced a similar error while using OpenCV. After googling for a while I found out that the error might be with the new macOS. It does not allow un-versioned dylibs to be called. I found the solution here:

https://forums.developer.apple.com/thread/119429

In your terminal:

brew update && brew upgrade && brew install openssl
cd /usr/local/Cellar/openssl/1.0.2t/lib
sudo cp libssl.1.0.0.dylib libcrypto.1.0.0.dylib /usr/local/lib/
cd /usr/local/lib
sudo ln -s libssl.1.0.0.dylib libssl.dylib
sudo ln -s libcrypto.1.0.0.dylib libcrypto.dylib

when you say "pip3 install --upgrade packagname" what kind of packagename are you talking about? – Meyben May 20 '20 at 06:29
pip3 install --upgrade pyopenssl ? – Zinovy Nis May 27 '20 at 14:54
I was facing the same issue since I've updated my mac OS to Catalina. I just followed the steps here and didn't do the last one (pip install) and everything works fine for me now – Mauricio Reis Jan 14 '21 at 19:12

Run your Python script like this:

$ PYTHONVERBOSE=3 python your_script.py

Check the last statement before Abort trap: 6, such as:

import asn1crypto._perf._big_num_ctypes # precompiled from ...
Abort trap: 6

Then, run it in a standalone Python interpreter:

$ python
Python 2.7.17 (default, May  6 2020, 10:47:56) 
[GCC 4.2.1 Compatible Apple LLVM 11.0.3 (clang-1103.0.32.59)] on darwin
Type "help", "copyright", "credits" or "license" for more information.
>>> import asn1crypto._perf._big_num_ctypes
Abort trap: 6

Then you know that the problem is originated from the asn1crypto module, in this case. Dig into that file and find more...

But for this particular case, just delete the directory of asn1crypto package and try again. (pip uninstall asn1crypto may not work.)

This is exactly what I needed to find out what was causing the problem for me. I was still getting these aborts even though I tried using `brew` to `switch` my `openssl` versions. It is also funny to see my problem also stems from the `asn1crypto` package. — Karthic Raghupathi, Jun 12 '20 at 20:49

I have found the reason why this error appears. It is because I use the library TKinter, if I comment out the lines where I use TKinter, this error does not appear and it continues to execute the program.

I will edit this answer when I discover which is the proper way to use TKinter in OSX. But my main concern first is the pyglet animation, which does not work in OSX, but it does in Windows.

You haven't told us what you mean by using a "pyglet animation" nor the way in which it "doesn't work". We can't help you with so little detail. Code and/or error information is essential to get any useful answer – Jon Jun 20 '14 at 10:37
@Jon, I have posted [another question](http://stackoverflow.com/questions/24324985/pyglet-script-works-in-windows-but-not-in-osx) regarding the animation, thank you for your feedback. – jl.da Jun 20 '14 at 10:41

The error message doesn't tell us very much in this case. What you need to do (in debugging in general) is work out what succeeds and what fails in order to narrow down the problem.

Start with a script that just imports pyglet. If that works then import pyglet and open a window etc...

Report back when you know what line causes the error to occur.

thanks for the answer. I have finally found why this error appeared. It is because I use TKinter, when I comment out the lines where this library is used, the error does not appear. However, the animation that I expected and works on Windows does not appear. Therefore I will follow your advice and start a simple script. – jl.da Jun 18 '14 at 15:17

I was getting the same failure on importing asn1crypto in Python (on MacOS 10.15.5). Uninstalling then re-installing openssl using brew worked for me:

brew uninstall --ignore-dependencies openssl

brew warned me that there were some files remaining which were not deleted (e.g. /usr/local/etc/openssl@1.1/cert.pem) which I moved to a backup location:

sudo mv /usr/local/etc/openssl@1.1 ~/openssl@1.1-usrlocalbackup

Then reinstalling openssl using brew cured the problem:

brew install openssl
