As previously asked: what board are you using? There might be a simple
response to your issue, but you've yet to state the board you're using. You
will not get any useful responses until you answer this very, very simple
question.

If you can't "pip install", you'll probably have to build from source and
the board will likely matter very much. Building from source isn't normally
terribly difficult, but no one here can help you if we don't know your
environment.

Help us help you.
