Run Scripts\activate.bat if your shell is cmd, or Scripts\activate.ps1
if you're using PowerShell. These are shell scripts. Do not run them
with Python.

>From the outset, use an elevated console and make sure you use the
desired version of Python when you install distribute/setuptools (use
distribute in 3.x). Be explicit here. For example, if 2.7 is in
C:\Python27, run
CWD\>C:\Python27\python setup.py install
CWD is substituting here for your actual "current working directory",
as displayed in the default cmd shell prompt.
Or use pylauncher (installed with 3.3):
CWD\>py -2.7 setup.py install
Then install pip with easy_install:
CWD\>C:\Python27\Scripts\easy_install -Z pip
Finally virtualenv:
CWD\>C:\Python27\Scripts\pip install virtualenv
If you're using Python 3.3, you may instead want to use the new
virtual environment module "venv" described in PEP 405:
http://www.python.org/dev/peps/pep-0405
Once the system-wide installation is finished you no longer need to
(and really shouldn't) work in an elevated console.
----
Generally I recommend using pip instead of easy_install. However, if
you have exe installers for pre-compiled packages, you can install
them with easy_install, at least if the installer is built with
distutils. pip can't do this. For example:
(gmapenv) CWD\>easy_install -Z package-XXX-py2.7.exe
Note that "(gmapenv)" in the prompt signals that the "gmapenv" virtual
environment is active. Run "deactivate" to quit the virtual
environment and restore the original PROMPT and PATH.
