Status and License

Usage

The easiest way to create virtualenv to open a terminal and type:

python -murllib http://tiny.cc/ve-setup | python
. ./python/bin/activate

You can address It by full URL or pass any virtualenv option:

python -murllib https://github.com/generalov/virtualenv-setup/raw/1.0/ve_setup.py \
   | python - --no-site-packages .venv

Common usage pattern:

Usage: ve_setup.py [[virtualenv options] DEST_DIR]

Win32

Certainly, sir! I tested It with some sort of wine:

wine C:/python26/python.exe ve_setup.py

What It Does

ve_setup.py is tool to download virtualenv and create new isolated Python environment.

The basic problem being addressed is to create isolated Python environment on systems where virtualenv package is not installed. Imagine you have an hosting with very old setuptools and without virtualenv. How can you create isolated Python environment?

ve_setup.py can help you. It download ez_setup.py to fetch desired version of the virtualenv package into a temporary directory. Then It creates new isolated Python environment with your arguments in the given directory (named python by default).

Using ve_setup

If you want to use virutalenv in your script, just put ve_setup.py into any directory on the PYTHONPATH, and add this to the top:

#!/usr/bin/env python
try:
    from ve_setup import use_virtualenv
except ImportError:
    import urllib
    urllib.retrive("http://tiny.cc/ve-setup", 've_setup.py')
    from ve_setup import use_virtualenv

use_virtualenv(['--distribute', "python"], requirements="requirements.pip")

This will create virtualenv if needed, install requirements and activate it.
