I have written a python27 module and installed it using python setup.py install.
Part of that module has a script which I put in my bin folder within the module before I installed it. I think the module has installed properly and works (has been added to site-packages and scripts). I have built a simple script "test.py" that just runs functions and the script from the module. The functions work fine (the expected output prints to the console) but the script does not. 
I tried from [module_name] import [script_name] in test.py which did not work.
How do I run a script within the bin of a module from the command line?
Are you using distutils or setuptools?
I tested right now, and if it's distutils, it's enough to have
scripts=['bin/script_name']
in your setup() call
If instead you're using setuptools you can avoid to have a script inside bin/ altogether and define your entry point by adding
entry_points={'console_scripts': ['script_name =  module_name:main']}
inside your setup() call (assuming you have a main function inside module_name)
are you sure that the bin/script_name is marked as executable?
what is the exact error you get when trying to run the script? what are the contents of your setup.py?
