Learn how to create Virtual Environment using venv and activate using executables. What is a Virtual Environment? Virtual Environments help create, manage and isolate environments for the project, each one using same or different versions of the executables.
What is a Virtual Environment?
Virtual Environments help create, manage and isolate environments for the project, each one using same or different versions of the executables.
Consider the following scenario where you have two projects: Project A and Project B, both of which have a dependency on the same library, Project C. The problem becomes apparent when we require different versions of Project C. Maybe Project A needs v1.0.0, while _Project B _requires the newer v2.0.0. This is a real problem for Python since it can’t differentiate between versions in the same directory.
With growing Python-compatible web frameworks like Django, Flask and increasing cloud services like AWS, Google Cloud, Heroku, linode, etc. along with a multitude of companies taking their businesses online and each project needing its own libraries and versions, it becomes important to isolate each project.
In this guide we look forward to creating a Virtual Environment in a project folder.
Consider a folder/directory My_Project in which we want to create a virtual environment named Test
1. Check if Python has been installed correctly.
Run Command Prompt (CMD) or Windows PowerShell window and navigate to the My_Project directory and execute
python followed by
exit() If you get the same output as in the image, then everything is working fine.
If it says
python is not recognized as an internal or external command, operable program or batch file then you have to add the directory in which python.exe exists to the Environment variables.
