E319: No "python3" provider in neovim 0.4.4 with ultisnips!

[jayli]

You may meet this error in neovim 0.4.4 with ultisnips:

Error detected while processing /home/xxx/.vim/plugged/ultisnips/autoload/UltiSnips.vim:
line    7:
E319: No "python3" provider found. Run ":checkhealth provider"

Which means python neovim package is missing. Fix it via pip3 install neovim

@jayli what do I do when I get this error? (python3 -m pip install neovim gives the same error). neovim is installed with homebrew (brew install neovim)

❯ pip3 install neovim
error: externally-managed-environment

× This environment is externally managed
╰─> To install Python packages system-wide, try brew install
    xyz, where xyz is the package you are trying to
    install.

    If you wish to install a Python library that isn't in Homebrew,
    use a virtual environment:

    python3 -m venv path/to/venv
    source path/to/venv/bin/activate
    python3 -m pip install xyz

    If you wish to install a Python application that isn't in Homebrew,
    it may be easiest to use 'pipx install xyz', which will manage a
    virtual environment for you. You can install pipx with

    brew install pipx

    You may restore the old behavior of pip by passing
    the '--break-system-packages' flag to pip, or by adding
    'break-system-packages = true' to your pip.conf file. The latter
    will permanently disable this error.

    If you disable this error, we STRONGLY recommend that you additionally
    pass the '--user' flag to pip, or set 'user = true' in your pip.conf
    file. Failure to do this can result in a broken Homebrew installation.

    Read more about this behavior here: <https://peps.python.org/pep-0668/>

note: If you believe this is a mistake, please contact your Python installation or OS distribution provider. You can override this, at the risk of breaking your Python installation or OS, by passing --break-system-packages.
hint: See PEP 668 for the detailed specification.
