Upgrade pipx

On macOS:

brew update && brew upgrade pipx

On Ubuntu Linux:

sudo apt upgrade pipx

On Fedora Linux:

sudo dnf update pipx

On Windows:

scoop update pipx

Otherwise, upgrade via pip:

python3 -m pip install --user -U pipx

Note: Upgrading pipx from a pre-0.15.0.0 version to 0.15.0.0 or later

After upgrading to pipx 0.15.0.0 or above from a pre-0.15.0.0 version, you must re-install all packages to take advantage of the new persistent pipx metadata files introduced in the 0.15.0.0 release. These metadata files store pip specification values, injected packages, any custom pip arguments, and more in each main package's venv.

If you have no packages installed using the --spec option, and no venvs with injected packages, you can do this by running pipx reinstall-all.

If you have any packages installed using the --spec option or venvs with injected packages, you should reinstall packages manually using pipx uninstall-all, followed by pipx install and possibly pipx inject.
