virtualenvwrapper is a set of shell scripts that provide some shortcuts for creating and deleting virtual environments and otherwise managing your development workflow, making it easier to work on more than one project at a time without introducing conflicts in their dependencies. It’s a popular tool among Python developers.

Here’s a quick guide to using virtualenvwrapper:

Installation

First, make sure you have virtualenv installed:

Next, you can install virtualenvwrapper:

For Windows users, there’s an alternative called virtualenvwrapper-win:

Configuration

You’ll need to add some lines to your shell startup file. For example, in the bash shell, you’d add this to your ~/.bashrc or ~/.bash_profile:

Make sure to source your shell startup file to apply the changes:

Or restart your terminal session.

Basic Commands

• Create a Virtual Environment: mkvirtualenv myenv will create a virtual environment named “myenv.”
• Work on a Virtual Environment: workon myenv will activate the virtual environment named “myenv.”
• Deactivate a Virtual Environment: deactivate will exit the virtual environment you’re currently in.
• Delete a Virtual Environment: rmvirtualenv myenv will delete the virtual environment named “myenv.”
• List Virtual Environments: lsvirtualenv will list all of your virtual environments.

These commands make managing multiple Python projects on the same system much easier, as they allow you to maintain separate dependencies for each project. That way, you don’t run into conflicts if different projects require different versions of the same packages.
