Stuck in the tutorial - aspen can't find the handler "handy" :-(

[Jan Winkelmann]

Hi everybody,

I have no idea why this doesn't work. I set up everything just like
said in the tutorial, but on starting aspen in this directory he fails
with error "ImportError: No module named handy.py [handlers.conf, line
3]". Here's the whole output: (listing 1)
$ aspen
launching child process
starting child server
Traceback (most recent call last):
File "/usr/local/bin/aspen", line 3, in <module>
aspen.main()
File "/usr/lib/python2.5/site-packages/aspen-0.8-py2.5.egg/aspen/

start_server()
File "/usr/lib/python2.5/site-packages/aspen-0.8-py2.5.egg/aspen/

colon.py", line 43, in colonize
exec 'import %s as obj' % modname
File "<string>", line 1, in <module>
ImportError: No module named handy.py [handlers.conf, line 3]

then he writes this (listing 2)

Exception in thread Thread-1 (most likely raised during interpreter
shutdown):

and starts at the "starting child server" part of fig. 1 and begins to
loop this.

I don't know if this helps but this simple Ctrl+L in vim didn't work
either, he just printed the python code and the HTML code on the
website. However he only starts the server if __/etc/handlers.conf
doesn't link to any handlers (i only tried it without one)

===

Here are some stats, I don't know if they help:

$ python --version
Python 2.5.2
--
$ uname -a
Linux keks-t43 2.6.25-gentoo-r7+keks-0.5 #9 SMP Sat Oct 18 03:06:37
CEST 2008 i686 Intel(R) Pentium(R) M processor 1.86GHz GenuineIntel

--
>>> import aspen
>>>

works fine.

If you need any more info, feel free to ask me!

Thanks in advance, Jan

Jan,

Where is handy.py relative to "this directory?" It should be in
./__/lib/python.

If that's not the problem, what does your handlers.conf look like?

> then he writes this (listing 2)

This is unrelated and harmless. Sorry for the error spam.

Sorry this took so long, I was busy with school and afterwards totally
forgot about it.

handy.py was in ./__/lib/python2.6. I renamed it to ./__/lib/python
and...aspen comes up - but 127.0.0.1:8080 looks like this:

My ./__/etc/handlers.conf looks like this:
--
fnmatch aspen.rules:fnmatch

[handy:handle]
fnmatch *.asp
--
Any ideas?
