Python 3.3 includes a script, pyvenv, which is used to create virtual environments. However, Distribute and pip are not installed in such environments - because, though they are popular, they are third-party packages - not part of Python. The Python 3.3 venv machinery allows customisation of virtual environments fairly readily. To demonstrate how to do this, and to provide at the same time a script which might be useful to people, I've created a script, pyvenvex.py, at https://gist.github.com/4673395 which extends the pyvenv script to not only create virtual environments, but to also install Distribute and pip into them.
Excellent and one step closer to sane package management .... I wonder if you could not source instead the code that is directly in the virtualenv.py scripts? it also includes the packed distribute and pip .... Meaning that would allow the installation entirely offline (with the --never-download venv flag)
And btw, why pip is not part of the standard Python? This is nowadays officially recommended on Pypi as the tool to use to install package.... Per http://pypi.python.org/pypi "Get Packages: To use a package from this index either "pip install package" (get pip) or download, unpack and "python setup.py install" it."
This does not make sense to me: I know about some of the controversies .... but this is rather inconsistent to recommend using a tool and not supporting it directly.
I think the short answer, as always, is: getting pip into the stdlib would require a tremendous amount of work that some would have to want to do[1] before it could happen. IIUC, the current direction is something like "get a packaging standard into the stdlib that people can build tools on top of" c.f. distutils/packaging. [1] And that work is not always technical. A lot of the hard work is getting people to agree on things.
