[PyQt] pkg_resources error....

[John M. Hackett]

I'm not sure if this is aPyQt/Qt, python, or pyqtdeploy issue... 

I have managed to get my app to build successfully and it all runs correctly within the IDE. When I run the binary the app start OK but when it tries to set up the scheduler ( apscheduler) it get this traceback: 



Traceback (most recent call last): 

File "PythonLogin_v1.03.py", line 1342, in <module>

NotImplementedError: Can't perform this operation for loaders without 'get_data()' 




It seems to be a known problem (for googling the error message) but what I have found does not seem to be very useful in terms of correcting the issue - any ideas? Is there a module missing? (both tzlocal and pytz are installed). 




The actual line in my code generating the error (line 573) is 




self.myTimer = QtScheduler() 




so it seems there is something between QtScheduler and getting the local timezone which is breaking pkg_resources. 




System info: ubuntu14.04, Python 2.7.6, Qt5.5. Target is the host system (i.e. not cross compiling). I have compiled both in the main environment and in a 2.7.6 virtualenv and get the same error in both cases. 




Has anyone come across this and/or can suggest a fix?
