page	Installation in Python virtual environment	How to install Home Assistant in a Python virtual environment.	2016-4-16 16:40	true	false	true	true	/getting-started/installation-virtualenv/

If you already have Python 3.5 or later installed, you can easily give Home Assistant a spin.

It's recommended when installing Python packages that you use a virtual environment. This will make sure that your Python installation and Home Assistant installation won't impact one another.

(If you're on a Debian based system, you will need to install Python virtual environment support using apt-get install python3-pip python3-venv)

1. Create a virtual environment:

   python3 -m venv homeassistant
   

2. Open virtual environment:

   cd homeassistant
   

3. Activate virtual environment:

   source bin/activate
   

4. Install Home Assistant:

   python3 -m pip install --upgrade homeassistant
   

5. Run Home Assistant:

   hass --open-ui
