Python ImportError

Question

$ bin/python src/app/utils/loader.py newTasks checkForStuff 
Traceback (most recent call last):
  File "bin/python", line 135, in <module>
    execfile(__file__)
  File "src/app/utils/loader.py", line 154, in <module>
    module = __import__(args.module)
ImportError: No module named newTasks

from the following loader.py:

if __name__ == '__main__':
    parser = argparse.ArgumentParser(description='Runs python')
    parser.add_argument('module', metavar='module', help="the target module")
    args = parser.parse_args()
    module = __import__(args.module)

newTasks.py is in the same directory as loader.py. It works on my dev box, I did an svn export to staging and the above happened. Any pointers?

Only material difference I can work out is this time I'm running out of virtualenv.

EDIT: I changed the command line to:

$ bin/python src/app/utils/loader.py utils.newTasks checkForStuff 

and the module was found ok. But my next command is to call one of the module functions checkForStuff :

parser.add_argument('func',metavar='function', help="the target function name")
...
func_param = getattr(module,args.func)

and now it cannot find the function?

Traceback (most recent call last):
  File "bin/python", line 135, in <module>
    execfile(__file__)
  File "src/app/utils/loader.py", line 156, in <module>
    func_param = getattr(module,args.func)
AttributeError: 'module' object has no attribute 'checkForStuff'

If I go into bin/python:

>>> import utils.newTasks as nt
>>> nt.checkForStuff
<function checkForStuff at 0x29b2f50>

This is annoying!

bin/python is not the python binary on your staging machine. Check whether it inserts the scripts directory into sys.path as ordinary python does.
