How can I install Scipy for pypy from pyenv?

Question

I use pypy via pyenv on Ubuntu 18.04. How can I install scipy for this setup? Installing scipy for pypy is possible, but maybe I need to do extra steps using pyenv?

The Error

This is the answer which was deleted from this question and where I already commented that it doesn't help. — Martin Thoma, Feb 20 '20 at 05:24
@aprospero I'm sorry, I don't remember ... but I also don't think so. I decided not to use pypy when I use numpy / scipy. — Martin Thoma, Apr 24 '20 at 19:05
Ok, thank you anyway, I am facing the same problem right now! — aprospero, Apr 24 '20 at 19:52

The problem is the missing cstddef, which would seem to indicate you are missing the g++ include libararies. Did you install g++ or only gcc?
