Set Up a Virtualenv and Install Flask
Create an isolated environment and pip install Flask.
Why Isolate Projects
Each project wants its own package versions. A virtual environment keeps Flask and friends separate from your system Python.
Meet venv
Python ships venv, a built-in tool that creates a private folder holding a fresh, isolated copy of pip and packages.
