| Installing virtualenv |
| ===================== |
| `virtualenv <http://pypi.python.org/pypi/virtualenv>`_, sets a |
| "virtual environment" that allows you to run different projects with separate |
| libraries side by side. This is a good idea both for development and |
| production, as it'll assure that each project uses their own library versions |
| and don't affect each other. |
| |
| .. note:: |
| For App Engine development, virtualenv is not necessary. The SDK provides |
| a "sandboxed environment" that serves almost the same purposes. |
| |
| If you don't have a package installer in your system yet (like ``pip`` or |
| ``easy_install``), install one. See :ref:`tutorials.installing.packages`. |
| |
| Then follow these steps to install virtualenv: |
| |
| **1.** To install it on a Linux or Mac systems, type in the command line: |
| |
| .. code-block:: text |
| |
| $ sudo pip install virtualenv |
| |
| Or, using easy_install: |
| |
| .. code-block:: text |
| |
| $ sudo easy_install virtualenv |
| |
| **2.** Then create a directory for your app, access it and setup a virtual |
| environment using the following command: |
| |
| .. code-block:: text |
| |
| $ virtualenv env |
| |
| **3.** Activate the environment. On Linux of Mac, use: |
| |
| .. code-block:: text |
| |
| $ . env/bin/activate |
| |
| Or on a Windows system: |
| |
| .. code-block:: text |
| |
| $ env\scripts\activate |
