How to install pypy3 on the Raspberry Pi
This post shows you an easy way of getting pypy3 running on the Raspberry Pi. I used Raspbian Buster on a Raspberry Pi 3 for this example. On Raspbian buster this will install pypy3
7.x!
First install pypy3
and virtualenv
:
sudo apt update && sudo apt -y install pypy3 pypy3-dev virtualenv
Now we can create a virtualenv
to install pypy
packages into:
virtualenv -p /usr/bin/pypy3 ~/pypy3-virtualenv
Now we can activate the virtualenv
. You need to do this every time you want to use pypy
, for each shell / SSH connection separately:
source ~/pypy3-virtualenv/bin/activate
If your shell prompt is now prefixed by (pypy3-virtualenv)
you have successfully activated the virtualenv
:
(pypy3-virtualenv) uli@raspberrypi:~ $
Now python points to pypy3
and pip
will install packages locally to ~/pypy3-virtualenv
.
Now you can use e.g.
python3 myscript.py
to run your script (both python
and python3
will point to pypy3
if you activated the virtual environment!).
Note: Installing pypy3-dev
is not strictly neccessary to get pypy3
running, but you need it in order to compile native librarie like numpy
.
