Installing, Activating and Deactivating Virtualenv
To install virtualenv we are going to use pip, pip is a tool to manage and install Python packages.
1.sudo pip install virtualenv
To start with every project in python, we will first create a Virtual Environment.
For example my work-space is main directory for cloning all the projects. We will first create a new folder here for a project cloning.
2.mkdir myproject
Inside myproject, we will create a virtual environment with any name. Here we have created virtualenv with name venv.
3.cd myproject
4.virtualenv venv
Now start the virtual environment.
5.source venv/bin/activate
To stop virtualenv
6.deactivate
Note: If we want to specify python version for our project then the command looks like.
virtualenv venv -p python3.6
