Hi all,
I'm trying to run sage on WSL2 (Ubuntu focal 20.04.5 LTS), and after a
fresh install (sadly only version 9.0), running `sage` gives the following
error.
ModuleNotFoundError: No module named 'sage.cpython.string'
I happen to know that the packages are installed
in /usr/lib/python3/dist-packages/, and sage/cpython/string.pyx is in there.
What's particularly strange to me is that sage *can* find
`sage.misc.banner` (which is in the same dist-packages location).
Meanwhile, I can run `sage -python` and inspect `sys.path` manually (it has
the right dist-packages path in it), but importing sage.all in that context
fails with "ModuleNotFoundError: No module named 'cysignals.signals'" and
similar with other imports.

it's there in** /usr/lib/python3/dist-packages/cysignals/)*
I understand the recommendation is to use conda or build from source to get
a version > 9.2, but is there a quick fix I can do to link the sage-python
to these libraries? Maybe an existing trac issue I can read through
workarounds? The reason I ask is because I'm working on a library that uses
sage and it's a bit of a pain to fire up docker (and worse, the sagemath
docker image had known issues (only just now seeing
<https://trac.sagemath.org/ticket/34242#comment:21> that a new docker image
got pushed; still, working in docker is a bit inconvenient))
Any ideas? Further steps for investigation?
