Install a Python <= 3.8.x version using pyenv (recommended)

# With Chocolatey choco install pyenv-win

# With pyenv-installer curl https://pyenv.run | bash

# With homebrew brew update brew install pyenv

Check if pyenv was installed sucessfully, and if not got any error in this project

# Warning: Check if not got any error pyenv rehash

Install same Python version inside of the file .python-version

cd [project-folder] # Loads local version from .python-version file pyenv local # PS: The 3.8.2 Python version is latest available in Pyenv for Windows.  # On Unix systems, is possible install 3.8.8, for example. pyenv install 3.8.2 # Check the installed version python --version

Create a Virtual Environment to store the packages dependencies, and activate it

python -m venv venv # Activate # Windows .\venv\Scripts\activate.bat # Unix systems ./venv/Scripts/activate

Install all dependencies

pip install -r .\requirements-dev.txt

Define your interpreter in your preferable IDE (Visual Studio, VSCode...) from the virtual environment. In this case, we are using Pycharm as example:

1. Click on File => Settings => Python Interpeter
2. Add your interpreter from your virtual environment (recommended)
3. If you prefer, download from the official https://www.python.org/downloads FTP and clicking on "New environment", as showed in the picture below:
