I was convinced that I needed to add every egg to the sys.path to be 
able to import it, well if I don't
actually need the local pypi-server than even better...
I was, however, doing some experiments, and not figuring out how it works.

I created an egg_directory where I added the mock library egg, I wanted to
see if I was able to find it, and that's what I do.


from pkg_resources import working_set, Environment, Requirement
from os.path import abspath

env = Environment(abspath('egg_directory'))
env.scan()

r = Requirement.parse('mock')
print(working_set.find(r))


It actually finds something but my USER installed version, not the local 
version
in the subdirectory.
And from my understanding of the doc it should not even look for in the 
global
sys.path, am I doing something wrong?
