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 --features jit
- Bootstrap pip with rustpython
May 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

Successfully installed pip-23.2.1
- Test pip is initially working:
$ rustpython -m pip list
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 pip
May 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)
