Pipx install instructions not working: no such file or directory

Describe the bug When following the instructions to get the pipx backend working, an No such file or directory (os error 2) error is issued when trying to install something.

To Reproduce

$ mise use -g python
$ pip install --user pipx
$ mise install pipx:psf/black
mise failed to execute command: pipx install git+https://github.com/psf/black.git@22.1.0
mise No such file or directory (os error 2)
mise Run with --verbose or MISE_VERBOSE=1 for more information

This is also true for normal PyPi packages.

Expected behavior Packages install correctly.

Additional context I had it working before. Then I started over from scratch using mise uninstall python --all and following the instructions above.

I think I saw the same issue as this, which does seem related indeed to #2458. To reproduce:

$ cd ~
$ curl https://mise.run | sh
$ echo 'eval "$(~/.local/bin/mise activate bash)"' >> ~/.bashrc
$ . .bashrc
$ mise --version
2024.8.15 linux-x64 (14bab0e 2024-08-28)
$ mise settings set experimental true
$ mise settings set pipx_uvx true
$ mise use -g uv
$ mise use -g pipx:black  # this works
$ nvim ~/.config/mise/config.toml  # edit by including for example "pipx:poetry" = "latest" in tools
$ cat ~/.config/mise/config.toml
[tools]
uv = "latest"
"pipx:black" = "latest"
"pipx:poetry" = "latest"
neovim = "latest"

[settings]
experimental = true
pipx_uvx = true
$ mise i
mise failed to execute command: uv tool install poetry==1.8.3
mise No such file or directory (os error 2)
