Installing and upgrading Datasette plugins with pipx

If you installed datasette using pipx install datasette you can install additional plugins with pipx inject like so:

$ datasette plugins
[]

$ pipx inject datasette datasette-json-html
  injected package datasette-json-html into venv datasette
done! ✨ 🌟 ✨

$ datasette plugins
[
    {
        "name": "datasette-json-html",
        "static": false,
        "templates": false,
        "version": "0.6"
    }
]

Thanks Matthew Somerville.

I then had to figure out how to upgrade them. Thanks to https://github.com/pipxproject/pipx/issues/79 I figured out the following recipe using pipx runpip datasette install -U name-of-plugin:

% datasette plugins
[
    {
        "name": "datasette-vega",
        "static": true,
        "templates": false,
        "version": "0.6"
    }
]

$ pipx runpip datasette install -U datasette-vega

$ datasette plugins

    {
        "name": "datasette-vega",
        "static": true,
        "templates": false,
        "version": "0.6.2"
    }
]

I added all of this to the Datasette docs here: https://docs.datasette.io/en/latest/installation.html#using-pipx (see https://github.com/simonw/datasette/issues/756).
