Virtualenv en Slackware 12.1

Dedicado a Katai ^.^”

Teniendo Python 2.4 instalado, vamos a proceder a realizar un virtualenv:

Virtual Python Environment builder:
virtualenv is a successor to workingenv, and an extension of virtual-python.
What it Does?:
virtualenv is a tool to create isolated Python environments.

A lo bestia, digamos que virtualenv es un ‘chroot’ de la instancia python que vamos a utilizar para trabajar. Mas data Aqui

Creando un Python ‘Virtual’:
Si estas en un sistema Linux, BSD, Cygwin o algun otro de OS de tipo UNIX y no tienes acceso de root, puedes crear tu propia instalacion ‘virtual’ de python, cual utiliza sus propias librerias y enlaza algunas otras con las librerias de python del sistema.

Proseguimos descargando virtual-python.py:

bash-3.1$ wget http://peak.telecommunity.com/dist/virtual-python.py

Lo instalamos:

bash-3.1$ mkdir ~/.vpython
bash-3.1$ python2.4 virtual-python.py –help
usage: virtual-python.py [options]

options:
-h, –help show this help message and exit
-v, –verbose Increase verbosity
–prefix=PREFIX The base directory to install to (default ~)
–clear Clear out the non-root install and start from scratch
–no-site-packages Don’t copy the contents of the global site-packages dir
to the non-root site-packages

bash-3.1$ python2.4 ./virtual-python.py –prefix=/home/lain/.vpython
Creating /home/lain/.vpython/lib/python2.4
Creating /home/lain/.vpython/lib/python2.4/site-packages
Creating /home/lain/.vpython/include/python2.4
Creating /home/lain/.vpython/bin
Copying /usr/local/bin/python2.4 to /home/lain/.vpython/bin
You’re now ready to download ez_setup.py, and run
/home/lain/.vpython/bin/python ez_setup.py
bash-3.1$

Ok, vamos a correr ez_setup.py (easy_install) mas datos Aqui

bash-3.1$ /home/lain/.vpython/bin/python ez_setup.py

Proseguimos con nuestra meta, estamos en condiciones de instalar virtualenv!

bash-3.1$ ~/.vpython/bin/easy_install-2.4 virtualenv
Searching for virtualenv

bash-3.1$

Ahora a crear nuestro python environment!

bash-3.1$ mkdir ~/.pyenv
bash-3.1$ ~/.vpython/bin/virtualenv ~/.pyenv
New python executable in /home/lain/.pyenv/bin/python
Installing setuptools………….done.

Voila! terminamos

bash-3.1$ ~/.pyenv/bin/python

El sabor de la victoria! ^.^”
Ahora podemos crear tantos pyenv como queramos en nuestro sistema y utilizar cada uno independientemente en nuestros proyectos .
