I'm on Ubuntu 22.04 "Jammy". I've installed pypy3, and I'm trying to install scipy for it.
This error message was printed out:
ndos@ndos-desktop:~$ pypy3 -m pip install scipy --upgrade

I focused on this line:
../../scipy/meson.build:40:0: ERROR: Command "/usr/bin/pypy3 -c import os; os.chdir(".."); import numpy; print(numpy.get_include())" failed with status 1.
As far I've understood, this "command" is invalid because of the nested ""s. Either the inner "" must be escaped, or be replaced by single quotes ''.
How should I resolve this bug?
SciPy 1.9.0 was released last week and does not yet build using the new meson backend. The best place to track availablility is on the scipy issue tracker, for instance this issue. I would recommend using the pre-built conda packages for PyPy since that will save a lot of headache around building complicated packages like Scipy. Directions are here https://conda-forge.org/docs/user/tipsandtricks.html#using-pypy-as-an-interpreter.
