I have tested importing and actually connecting and using a MySQL
database, although it issues some warning:

From that message it looks like this "python" is /usr/local/bin/
python (i.e. a separate installation than Apple's system python at /
usr/bin/python and /System/Library/Frameworks/Python.framework).

You can tell for sure by doing:

$ which python

Traceback (most recent call last):

mysql_connect_test.py", line 11, in <module>

ImportError: No module named MySQLdb

I suspect that this is because your run of Komodo Edit doesn't have
"/usr/local/bin" on its PATH and is using "/usr/bin/python" instead
of the one you typically use on the command line.

You can configure Komodo to know about /usr/local/bin by adding a
"PATH" setting in the "Environment" prefs panel. Arguably Komodo
should just add /usr/local/bin to its runtime PATH by default, but
unfortunately it currently doesn't. Komodo doesn't pick up your
normal bash shell environment because of problems trying to get that
information in general.

Please let me know (or on the komodo-discuss list [^1] or Komodo bug
database [^2]) if you have any problems getting that going.

Thanks, that seems to have worked. I added "/usr/local/bin" to the
PATH in the preferences Environment panel in Komodo. Then in
preferences I went into the Python pane and changed my selected
interpreter from "/usr/bin/pythonw" to the now available "/usr/local/

Thanks again,
