Module imports fine from interactive, not from script

[Joshua J. Kugler]

Yes, I've read this:
http://mail.python.org/pipermail/python-list/2006-August/395943.html
That's not my problem.

I installed PlanetPlanet <http://www.planetplanet.org/> via the
package's "setup.py install" command (as root). planet.py will not run,
however, giving me this error:

Traceback (most recent call last):
File "/usr/local/bin/planet.py", line 167, in ?
main()
File "/usr/local/bin/planet.py", line 124, in main
planet.logging.basicConfig()
AttributeError: 'module' object has no attribute 'logging'

But, from interactive session:

planet.py is simply executing:

import planet
..

..
# Activate logging
planet.logging.basicConfig()


I've checked permissions, I've checked import statements, everything I know
to check. Is there something terribly simple I'm missing?

Thanks!

Yes, I've read this:http://mail.python.org/pipermail/python-list/2006-August/395943.html
That's not my problem.

I installed PlanetPlanet <http://www.planetplanet.org/> via the
package's "setup.py install" command (as root). planet.py will not run,
however, giving me this error:

Traceback (most recent call last):
File "/usr/local/bin/planet.py", line 167, in ?

AttributeError: 'module' object has no attribute 'logging'

Your problem is that your script is called planet.py, the same as the
module you're trying to import. So from the script, "import planet"
finds the script itself (the script's directory is always added to
sys.path), and importing it as planet rather than importing the planet
module from site-packages.

The simplest fix is to not call the driver script "planet.py".

It's not exactly "terribly simple", but it is quite a common mistake
(I've certainly made it more than once...)

The directory containing the script you are executing is also added to
sys.path. Since you are executing a script called planet ...

Ah! That's it. That had never occurred to me, as I was under the impression
that your current *working* directory was added to sys.path, not the
directory of the script.

Thanks!
