Using Ubuntu 8.04, I downloaded pwytter 0.8 and attempted to install it via
the python setuptools.
I had to manually install setuptools and some misc. python libraries.

However, even after this I faced an error with pwCache missing. I copied
those pwcache.py files into the /usr/lib/..../pwytter-0.8-py2.5.egg
directory, which solved that issue, apparently.

However, now pwytter dies immediately when run.

The backtrace is included below:

Looks like Pwytter tries to find the theme directory in whatever directory you are
launching the program from. This assumption is fine for the Windows version but it is
not a good assumption when the program is running on Linux. If you run the installed
pwytter.py file from the main source directory, it works fine. The pwTheme.py file
should take advantage of __file__ to find out where the module is located
(os.path.dirname (__file__)). This won't work with a py2exe build since __file__ does
not exist so both cases have to be handled. Also, theme files don't get installed
with Pwytter.

Comment 2 by ryooh...@yahoo.com, Mar 24, 2009

Looks like the try method that I tested is already implemented in trunk. Should have
checked out trunk before making the last comment. However, I don't like the design of
pwytter.py importing pwTheme which then imports values from pwytter.py. __app_path__
should probably be defined in another module which will be imported by both
pwytter.py and pwTheme.
