How to use Python Virtualenv and Virtualenvwrapper on Windows? This guide will show you how to Install Python Virtualenv and Virtualenvwrapper. Virtualenv is a tool for creating isolated Python virtual environments, each with their own libraries and site-packages.
- Python3 Installed
First, open CMD and check Python version
If you can not find python version. Please install python3: https://www.python.org/downloads/
Install python virtualenv using pip
pip install virtualenv
Install virtualenvwrapper for Windows
Virutalenvwrapper will help you to organize your environment in one place and control it easily.
pip install virtualenvwrapper-win
Optional: Setup VSCode
If you use VScode, you need to set default terminal is Command Prompt (cmd). Virtualenv does not function correctly in Windows Powershell
Press F1 –> Type Terminal: Select default profile –> Choose Command Prompt
Open new terminal in VScode
Working with virtualenvwarpper
Virtualenvwrapper is a set of extensions to virtualenv 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.
You can open VScode Terminal (cmd) or using Windows CMD. Personally, I will use VScode Terminal
1. Create sample virtualenv
mkvirtualenv project01 mkvirtualenv project02
Virtual environments are located at C:\Users\yourusername\Envs. All virtual environments are place in one place. That’s awesome !!!
2. List current virtual environment
You can easily see current virtual environment
3. Access specified virtualenv
Access virtualenv by using command: workon “virtual-environment-name”.
Example: Access virtual environment named: project01
4. Set virtualenv directory
At this point, we did not set directory for this virtual environment. So you need to change to the directory every single time when you switch to different virutalenv. However, we can make it more easy by set directory for virtualenv, then your directory will be automatically when you access to any virtualenv.
After access project01. We set virtualenv directory: setprojectdir “Your Project Directory”
For example: C:\Myprojects\project01 is my Django Project
This command will set C:\Myprojects\project01 to Virtualenv named: Project01
Set directory for virutalenv named: Project02
workon project02 setprojectdir C:\Myprojects\project02
Verified that project directory change when you access any virtualenv
workon project01 >>> The working directory will be change workon project02 >>> The working directory will be change
Repeat step 1 to 4 for any virtualenv you need.
4. Test virtualenv packages isolation
Let install Django packages on project01 virtualenv
Switch to project01 virutalenv
Install Django package on project01 virutalenv
python -m pip install Django
List installed packages
Switch to project02 virutalenv to check installed packages
You can see that there is no package on project02
In this tutorial you setup virtualenv for isolated installed packages for every single projects. By default, the virutalenv need to located in your project folder and it will be a nightmare for you to manage if you have hundred of projects.
Virtualenvwrapper helps you to orginize virutalenv in one place and manage them easily.
