Running into a bit of an odd problem I hope someone can help with.

Envrionment:
* Ubuntu Server 14.04, 64-bit (Vagrant box)
* Python 3.4
* Django 1.8
* pyodbc 3.0.8

pyodbc installs fine. When I do python3 and then import pyodbc, that works fine.

When I do python3 manage.py shell and then import pyodbc, however, I get this:

Got a bit of help in IRC with someone suggested to turn on pdb trace on the run_shell command, which I did, but then I just get this:
*** SystemError: initialization of pyodbc raised unreported exception

I just can't figure out why it'd work in a plain python interpreter but not in the Django shell, and I'm not sure how to diagnose or troubleshoot further.

Appreciate any tips or suggestions anyone might have. Thanks!

Hi Matt,

I have been through something similar some days ago.

Reverting to the 3.0.7 pyodbc version worked for me.

If you are using pip, maybe you will need to use --allow-external and --allow-unverified flags. Be warned of the security issues of doing something like this.

Att,

Thanks for the response! Turns out that it was actually a bug in pyodbc that's already been fixed:
https://github.com/mkleehammer/pyodbc/issues/38

Working for me now, or at least the import is. :-) Running into another issue that'll hopefully be fixed soon:

Thanks again for the input!
