Working on a project that uses pyexcel to read and write .xls files which is compiled using py2exe.
I get this error after compiling and confirming that pyexcel, pyexcel-io and pyexcel-xls are in the library.zip folder.
Traceback (most recent call last):

here is my project library
Short Answer
You will need to tell pyinstaller about the hidden imports about pyexcel-xls.
In order to package pyexcel-xls, you need to specify:
--hidden-import pyexcel_xls
--hidden-import pyexcel_xls.xlsr
--hidden-import pyexcel_xls.xlsw
Reference: mechanism of dynamic load module, confilict with pyinstaller/cx_freeze's execution
Long Answer
Since version 0.5.0, pyexcel uses lazy loading, which creates a problem for pystaller because not all modules are loaded on program's startup. Hence, you will need to tell pyinstaller about the missing imports(a.k.a hidden imports).

I use windows 7 and python 2.7
When I used py2exe to make an .exe file I get the error;
Traceback (most recent call last):
File "mainpy", line 17, in
File "main.py", line 17, in
File "zipextimporter.pyc", line 82, in load_module

ImportError: cannot import name _remove_dead_weakref
The same code could be used to make an .exe file in another computer so there is nothing wrong with the code in main.py. The minor environmental difference may cause this problem. I used pycharm, python 2.7.10 and py2exe 0.6.9. On another computer all other config are the same except using sublimetext instead of pycharm.
Could anyone please tell me how to fix that?
Another tricky thing is that
It is possible that the library does not exists for the other computer.Please check whether the library exists or not.
i have web app that i have developed using bottle micro framework.
However it crash a lot and all of them suddenly without any action ( without using the web app) . So i have reviewed the logs file and find the following errors (i have no idea what the causation of these errors):

OSError: [Errno 2] No such file or directory: '/tmp/bottle.gQmJc8.lock'
However the second error doesn't crash the application ( application would continue working ) but for the first one it's require manual work ( run the app again ).
i could schedule task using cron job to run the application when it's crash. but i'd like to know what's the problem in my app.
A few ideas come to mind:
Could there be another program on your machine (e.g., a cron job) that is deleting files from /tmp?
Are you using the latest version of Bottle? (From the line number in your stacktrace, it looks like you might not be.)
If nothing else works, try running without reloader=True (or use reloader=False). I looked at the Bottle code, and that change should at least work around the problem, even though we don't know the cause (yet).
Hope that helps.
Getting this error while using epub python package or you can say epub library for python , wondering what to do about it. please help..

From your question I presume you are using Python-Epub library from here: https://pypi.python.org/pypi/epub/0.5.1 and you are running in Windows.
It helps to know that EPUBs are essentially zip files. A typical bug in Python EPUB-handling libraries is attempting to build paths inside zip archive with os.path.join as if it were regular file system. On Windows os.path.join squeezes Windows file path separators (i.e., \\) that are not recognized by zipfile module.
This is a bug in epub library (which should be reported) yet you can easily get a work-around as following:
Determine where your epub sources are located:
python -c "import epub; print epub.__file__"
Add the following function to epub sources:
def zip_path_join(a, *p):
for b in p:
a += '/' + b
return a
Search epub sources for os.path.join and replace it with zip_path_join
Enjoy!
Thanks for the report of the issue. This is... well... shame on me, I should have fixed that a long time ago.
So, I've pushed a new version 0.5.2, and you can upgrade your version and see if it works as you expect (it should, yet I didn't run unit-test on any Windows env).
PS: I won't say "I got a life and stuff happen", but... yeah, that's just it...
I seem to have a strange error when trying to build my app
Couldn't import generation code: No module named generate_dynamic
What is strange about this error is that I can seem to resolve the error if I uninstall and re-install trigger.io but if I make any changes tot he config the error comes back and I have to uninstall and re-install each time I make a change to the configs. It never used to do this.

That is the debug. Note sure what is going on.
Thanks.
So it looks like its not resolved, I tried to update a module and the whole thing blew up again. I sent the logs to support so we will see how long this will take.
* Edit *
I was able to resolve this by deleting the trigger.Io directory ( the uninstall does not do this ) then reinstalling and importing my project again. Not sure what happened but it's working now
I deleted the .tempalte folder and re-built. Looks like the content of that folder got jacked during a failed or canceled build.
I'm planing to run a django project on google cloud plateform (GAE, Cloud SQL). The project uses several django reusable apps (libraries) like South, django-debug-toolbar, django-compressor, etc. So, i'm wondering if there is a way to manage all these libraries on appengine? if Yes, how.
PS: I've tried to define dependencies in the app.yaml file, but i'm getting errors:

Sorry, but at least South and django-compressor would not run on GAE.
GAE is a completely different platform. Yet you have SQL access to your tables, it's just an abstraction layer over a nonrelative database. There is no filesystem access, but there are tons of other limitations. Even Django itself could not be run on GAE without patches - you have to use special version, django-nonrel.
I would suggest to read more GAE documentation so you can decide if a particular application could be run there or not.
