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):
File ".\start-tgpy2exe.py", line 5, in ?
File "dist\Lib\site-packages\turbogears\__init__.py", line 8, in ?

File "dist\Lib\site-packages\pkg_resources.py", line 483, in resolve
pkg_resources.DistributionNotFound: TurboGears
[EMAIL PROTECTED] [dist]>
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",
line 92,
in ?
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
Traceback (most recent call last):

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
#
#
import os
import sys
import zipfile
import subprocess
# will this fix the missing linecache? nope...
