I often just want to do with easy_install is download an egg from pypi without installing it. I've studied the easy_install documentation and never found a way to do it. Even giving it the "-d" option results in easy-install.pth being created and other unwanted stuff.
Looking at the setuptools pydoc I worked out a way to do it:
import setuptools d = setuptools.Distribution() d.fetch_build_egg(requirement)
Voila! the egg is downloaded into cwd. It even seems built an egg from a tarball.
My question is, can I rely on this feature and is it the best way of doing what I want? I'd like to use it in my code and hope it stays. It would be ideal if I could do this through easy_install.
