More Exploration | why does Django need a virtualenv?

You should know when you develop a Django project with a 2.0 version and upload your website on a live server. after some time, sure, another version 3.0 is released, in which new functions or modules are released. It may be a chance, your old project as you developed in the 2.0 version may create some issues because when a new version is released it affects old versions.

For your knowledge, some tags of HTML are deprecated and did not use because they become old and in the replacement,  other new tags are developed. Same like this, Django developers also release updated versions that have extended functionalities.

Importance of keeping Django project in Virtual environment

If we did not create a virtual environment for our project then after releasing an updated version, our project may face some issues. So, to avoid such difficulties we keep our project in a virtual environment, which means new releasing will not affect our project.

Another reason is that you should know when you develop a Python-based project, then it should need some libraries/dependencies. Because without installing libraries you cannot achieve targets or goals as you want to get. So every python-based project needs libraries, every project has different dependencies.

So we create a virtual environment because we want to manage libraries/dependencies, which projects on which libraries depended?. So easy we can differentiate each project’s dependencies.

Important Note:

If you are confused about libraries and dependencies then it is for you!

The library is the collection of modules written in Python (if you are using the python-based library). It fulfills the requirements of a developer. If you need any functionality in the project then you need to install Libariy using pip command. So every project needs different libraries to complete functionalities.

Dependencies means, a project needs a library to complete its functionality, so that project depends upon that library because, without a required library, your project is incomplete, so that is why we say project dependencies.
