Virtualenv doesn't install pip
Question: I have installed `python3` via homebrew, updated `pip` & `setuptools`,
installed `virtualenv` via `pip`. Now I'm trying to create a virtual env.
Unfortunately, I can't get it to add pip to the virtualenv. Basically:

    
    
    $ ls -lha venv/bin/
    total 80
    drwxr-xr-x  9 foghin  staff   306B Jan 19 17:16 .
    drwxr-xr-x  6 foghin  staff   204B Jan 19 17:16 ..
    -rw-r--r--  1 foghin  staff   2.2K Jan 19 17:16 activate
    -rw-r--r--  1 foghin  staff   1.2K Jan 19 17:16 activate.csh
    -rw-r--r--  1 foghin  staff   2.4K Jan 19 17:16 activate.fish
    -rw-r--r--  1 foghin  staff   1.1K Jan 19 17:16 activate_this.py
    lrwxr-xr-x  1 foghin  staff     7B Jan 19 17:16 python -> python3
    -rwxr-xr-x  1 foghin  staff    13K Jan 19 17:16 python3
    lrwxr-xr-x  1 foghin  staff     7B Jan 19 17:16 python3.3 -> python3
    

AFAIK `pip` is supposed to be there as well. Creating the virtual env with
high verbosity yields this:

    
    
    Installing setuptools, pip...
      Running command /Users/foghin/code/tastekid/venv/bin/python3 -c "import sys, pip; pip...ll\"] + sys.argv[1:])" setuptools pip
      Ignoring indexes: https://pypi.python.org/simple/
      Requirement already satisfied (use --upgrade to upgrade): setuptools in /usr/local/lib/python3.3/site-packages
      Requirement already satisfied (use --upgrade to upgrade): pip in /usr/local/lib/python3.3/site-packages
      Cleaning up...
    ...Installing setuptools, pip...done.
    

This means that all the packages I install while the virtual env is activated
go to my global site packages (`/usr/local/lib/python3.3/site-packages`), but
they are not picked up by the sandboxed python.

How can I get `virtualenv` to properly install pip in my local environment?

**Update:** virtualenv version is 1.11.


Answer: As of this writing, Homebrew installs Python 3.3.3 (`$ brew info python3`).

And as of Python 3.3, Python's standard library now includes its own virtual
environment implementation, and does not require the virtualenv package. See
the [`venv` module documentation](http://docs.python.org/3/library/venv.html).
With the Homebrew Python 3 package, the command-line tool is named
`pyvenv-3.3`.

I believe using this implementation should resolve the issues you're
encountering.
