Hello,
I see no one has come up with a fix to the
"pkg_resources.DistributionNotFound: TurboGears" problem.
I was hoping to come back from holiday and it would magically be fixed
:(
I've come up with a hack solution that makes the "tg-admin makexe" work
for me. I still can't make
py2exe work however.
The basic problem seems to be the "easy_install.pth" that gets put into
the dist/Lib/site-packages. On
my system, the file contained the file names for the eggs in non-case
sensitive form. i.e the file names
were all lower case. This meant that TurboGears wasn't being registered
and picked up by
setuptool's "pkg_resources.py"
The following hack process works for me currently, but its far from
ideal. What is interesting is that the
easy_install.pth (with all lowercase filenames) works in the standard
system installed python, but not
in the packaged tg2exe version.
Maybe now I can py2exe the working tg2exe distro...
The hack fix:
* tg-admin makexe
* Open the "dist\Lib\site-packages"
* Delete the modules tg-admin has created for the turbogears project.
There
is no point having these around as well as the egg version.

I'm currently tracking it down.
It looks like pkg_resources isn't finding turbogears when its looking
for packages in the dist/Lib/site-packages directory. Turbogears is
there. If you do import turbogears you see its imported it its just the
call to require inside turbogears startup that isn't finding itself.
Copying
the egg file in doesn't solve the problem at the moment. More prints
are still needed.
I don't think I'll get this sorted before I go on holiday tomorrow,
maybe
next week sometime :(

I wonder if you were able to resolve the problem.
I'm getting the same error after using tg2exe:
pkg_resources.DistributionNotFound: TurboGears

Hello,
I've asked a similar question on the py2exe mailing list
(http://sourceforge.net/mailarchive/message.php?msg_id=37995269)
without any response. So I'm trying a revised version here instead.
Has anyone actually produced a turbogears app as an exe/standalone
distro which can then be installed via inno?
If so could I get a look at your setup.py / build script / magic system
you used to do this?
Any help on this would be really welcomed as I've spent a week banging
my head against the wall, with very little
beneficial affect.
What I've tried:
1. tg2exe:
Appears to gather everything together without errors. However on
running the app I just
keep getting the error:
[EMAIL PROTECTED] [dist]> ./python.exe start-tgpy2exe.pyc
Traceback (most recent call last):

2. Manually specifying all modules in py2exe:
I was talking to a friend and he suggested specifying the modules by
hand in py2exe. I gave this a go
without success. This was what I ended up with when I first tried using
py2exe. Manually specifying
linecache makes no difference:
[EMAIL PROTECTED] [dist]> ./WebPresence.exe
Traceback (most recent call last):
File
"c:\Python24\lib\site-packages\py2exe-0.6.6-py2.4-win32.egg\py2exe\boot_common.py",

import linecache
ImportError: No module named linecache
Traceback (most recent call last):
File "start-tgpy2exe.py", line 2, in ?
ImportError: No module named pkg_resources
[EMAIL PROTECTED] [dist]>
3. Trying non-egg installs of the dependancies:
This isn't really a runner as turbogears needs setuptools and I had to
do some code
hacks to the dependancies. When I tried this approach I ended up back
at the
turbogears not found message I got using tg2exe.
4. cx_freeze:
This was a last resort. I couldn't really find any examples of people
trying this
with turbogears. I built the exe although running it produced the
error:
[EMAIL PROTECTED] [tgpy2exe]> ./start-tgpy2exe.exe

I really don't know where to go from here :(
5. Forcing the customers to use linux.
The ideal solution, but sadly not an option where this app will get
deployed...
My system Info:
* python2.4 running on windows xp.
* py2exe 0.6.6 (installed via easy_install).
* turbogears 1.0 (installed via easy_install).
* build being run in cygwin (I'm not using its python).
My current monster/abomination setup.py:
#
# I'm following/implementing the rough approach here:
http://www.py2exe.org/index.cgi/ExeWithEggs
#
# 1. unpack zipped eggs, because I believe py2exe chokes on them when
resolving dependencies
# 2. keep track of the top level packages in the eggs
# 3. add all of the files in the eggs to the data_files, so that the
eggs are installed along side the main exe
# 4. build the exe
# 5. generate a new library.zip that does not include anything in the
top level packages found in step 2
