Virtualenvis a tool to create isolated Python environments. Virtualenv documentation. This article provides a quick summary to help you set up and use a virtual environment. Virtualenv: is the most popular library to create isolated Python environment. You can get it by running pip install virtualenv. It works by making an exact copy of your Python interpreter binary (the python or python3) in a local directory. Mkvirtualenv is a command that is a part of virtualenvwrapper. It is mainly used to create a new virtualenv (virtual environment). Also, it gets installed as part of virtualenvwrapper. Virtualenvwrapper a set of extension commands for Python virtual environment management.

Pip (Python Package Installer), official documentation for pip.

Usually Python3 comes with pip preinstalled. If you get an error 'pip command not found', use the following command to install pip:

Download get-pip.py, make sure you're saving file to Desktop

Mkvirtualenv

In your Command Prompt navigate to Desktop

Mkvirtualenv win

cd Desktop

Execute get-pip.py

python get-pip.py

Now pip should work system wide.

virtualenv

In your Command Prompt enter:

pip install virtualenv

Launch virtualenv

In your Command Prompt navigate to your project:

cd your_project

Within your project:

virtualenv env

Activate your virtualenv:

on Windows, virtualenv creates a batch file

envScriptsactivate.bat

to activate virtualenv on Windows, activate script is in the Scripts folder :

pathtoenvScriptsactivate

Example:

C:Users'Username'venvScriptsactivate.bat

Another way to install pip

Save the 'ez_setup.py' file to your desktop form https://bootstrap.pypa.io/ez_setup.py

In your Command Prompt navigate to Desktop:

cd Desktop

Execute ez_setup.py:

python ez_setup.py

install pip:

easy_install pip

virtualenvwrapper is a set of extensions to Ian Bicking’s virtualenv tool. The extensionsinclude wrappers for creating and deleting virtual environments andotherwise managing your development workflow, making it easier to workon more than one project at a time without introducing conflicts intheir dependencies.

Features¶

  1. Organizes all of your virtual environments in one place.
  2. Wrappers for managing your virtual environments (create, delete,copy).
  3. Use a single command to switch between environments.
  4. Tab completion for commands that take a virtual environment asargument.
  5. User-configurable hooks for all operations (see Per-User Customization).
  6. Plugin system for creating more sharable extensions (seeExtending Virtualenvwrapper).

Introduction¶

The best way to explain the features virtualenvwrapper gives you is toshow it in use.

First, some initialization steps. Most of this only needs to be doneone time. You will want to add the command to source/usr/local/bin/virtualenvwrapper.sh to your shell startup file,changing the path to virtualenvwrapper.sh depending on where it wasinstalled by pip or your package manager.

Now we can install some software into the environment.

We can see the new package with lssitepackages:

Of course we are not limited to a single virtualenv:

Switch between environments with workon:

The workon command also includes tab completion for theenvironment names, and invokes customization scripts as an environmentis activated or deactivated (see Per-User Customization).

postmkvirtualenv is run when a new environment iscreated, letting you automatically install commonly-used tools.

Through a combination of the existing functions defined by the corepackage (see Command Reference), third-party plugins (seeExtending Virtualenvwrapper), and user-defined scripts (see Per-User Customization)virtualenvwrapper gives you a wide variety of opportunities toautomate repetitive operations.

Shell Aliases¶

Mkvirtualenv Install

Mkvirtualenv

Since virtualenvwrapper is largely a shell script, it uses shellcommands for a lot of its actions. If your environment makes heavyuse of shell aliases or other customizations, you may encounterissues. Before reporting bugs in the bug tracker, please testwithout your aliases enabled. If you can identify the alias causingthe problem, that will help make virtualenvwrapper more robust.
