pip 26.1.1 not functional in venv (no attribute sys.addaudithook) #7956
Description
Summary
If I create a rustpython venv, and then upgrade pip, it can no longer install anything.
It works itself to, e.g., print its version:
$ pip install -U pip
<...>
Successfully installed pip-26.1.1
$ pip -V
pip 26.1.1 from <tmp>/rustpython3.14t/site-packages/pip (python 3.14)
Note: I am running
Python 3.14.0.alpha (heads/master:f3b83efce, May 22 2026, 13:11:57)
[RustPython 0.5.0 with rustc 1.95.0 (59807616e 2026-04-14)]
Expected
I can pip install stuff.
Actual
I can no longer pip install stuff:
$ pip install falcon
Requirement already satisfied: falcon in ./rustvenv/lib/rustpython3.14t/site-packages (4.2.0)

We do not support
pip>=26.1.1yet, and I'm not sure about how can we show a warning, to notify the users about this in the meantime until we have a fixcc: @youknowone

Thanks for feedback @ShaharNaveh!
On consideration, this issue could probably be distilled to an unsupported stdlib function,
sys.addaudithook(added in CPython 3.8).(This snippet passes on all other recent implementations, including PyPy and GraalPy.)

fwiw, pip 26.0.1 is the last release before that hook was added.
Introduced in pip's commit pypa/pip@fb01b1830 on 2026-04-14, shipped in 26.1
