Problem:
When trying to open PlatformIO in Visual Studio Code, you see the following error message:
PlatformIO: Can not find working Python 3.6+ Interpreter. Please install the latest Python 3 and restart VSCode
even though you have Python3 already installed.
Solution:
The issue here is not that PlatformIO can’t find Python 3, it is that you don’t have venv (virtual environments) installed for your Python version!
On Ubuntu/Debian, you can install it using
sudo apt -y install python3-venv
Alternatively you can install it using pip:
pip install virtualenv
