Description
Note
Possibly a regression or variant:
I'm seeing Similar AttributeError as before on MacOS but with: type_param.__default__
Summary
upgrading to pip==25.1.1 on macOS breaks rustpython -m pip (works with CPython 3.9.6 (builtin) and CPython 3.13.5 (stable) )

AttributeError: attribute '__default__' of 'ParamSpec' objects is not writableFull steps to reproduce on macOS
- (optional) cleanup and reset rustpython pip:
cargo uninstall rustpython || :
rm -vf ~/.local/bin/pip3.13 || :
rm -vf ~/.local/bin/pip || :
rm -vf ~/.local/bin/pip3 || :
rm -vfRd ~/.local/lib/rustpython3.13 || :- install rustpython with ssl via cargo (using homebrew's
rustc/cargo)
cargo install --git https://github.com/RustPython/RustPython rustpython --features ssl --feature jit- Bootstrap pip with rustpython
rustpython --install-pipMay see issues if not privileged (normal even with reference cPython)
e.g.,
$ rustpython --install-pip
Defaulting to user installation because normal site-packages is not writeable

Package Version
------- -------
pip 23.2.1
[notice] A new release of pip is available: 23.2.1 -> 25.1.1
[notice] To update, run: rustpython -m pip install --upgrade pip- run the reccomended update command
rustpython -m pip install --upgrade pipMay again see privilege warning (again normal even in reference cPython)
e.g.,
$ rustpython -m pip install --upgrade pip
Defaulting to user installation because normal site-packages is not writeable
Requirement already satisfied: pip in /Users/username/.local/lib/rustpython3.13/site-packages (23.2.1)
