Install Kivy

Before you can install Kivy, you need to have the Python environment and pip installed beforehand.

Install with pip:

python -m pip install –upgrade pip setuptools virtualenv

Create a virtual environment (optional):

The virtual environment will prevent installation conflicts with other Python versions and packages, which is optional.

1. Create a virtual environment kivy_venv named in the current directory:

python -m virtualenv kivy_venv

2. Activate the virtual environment, every time you start a new terminal, you must perform this step from the current directory:

For the Windows default CMD, execute it from the command line:
kivy_venvScriptsactivate
If you’re in the bash terminal on Windows, do the following:
source kivy_venv/Scripts/activate
If you’re using Linux, do the following:
source kivy_venv/bin/activate

 kivy_venv/bin/activate
