Virtualenv
Virtualenv creates an isolated space for a project, together with a copy of all you need to run a python program. The virtualenv tool can f.i. be used to solve problems that arise from having multiple python projects with different/incompatible demands to the setup of a given system.
Installing virtualenv:
[user@hostname ~]$ sudo apt-get install python-virtualenv
Creating an isolated space for a given project, with pip included:
[user@hostname ~]$ cd path/to/all/my/projects [user@hostname allmyprojects]$ virtualenv myproject_env [user@hostname allmyprojects]$ cd myproject_env [user@hostname myproject_env]$ source bin/activate
Adding python packages to the prosject:
[user@hostname myproject_env]$ pip install pythonpackage
- The packages will be stored in myproject_env/. They are only available to the given project.
To complete/close work on a project:
(myproject_env)[user@hostname myproject_env]$ deactivate
