Python virtual environment is tool that keeps every package in solated from system. This tool is required when you are working on different project on same machine. This will help to install same package with different version for different package.
In this article, we will install and create virtual environment for Python 3. We will use PIP to install the package. So let's start by installing virtual environment.
First open the Terminal and run the below command.
pip3 install virtualenv
or install using apt command for Debian based distribution system.
sudo apt-get install python3-venv
You have installed virtual environment package. Now we need to create virtual environment for every project. For that, go to the project directory in Terminal and run the command.
python3 -m venv new-env
This will create new-env directory with python files. This directory will install all packages when you activate environment. To use this environment, you need to activate it. To activate environment, run the below command.
source new-env/bin/activate
When you run this command, environment name will be prefixed in the new line.
Output:
(new-env) root@laravelcode-lenovo-g30-50:/var/www/python
Now all your python package will install and remove package in this environment. Once you done with environment package, you can deactivate the environment with deactivate command.
deactivate
