Cannot install plugins on desktop variant

[thomersch]

I've got Datasette Desktop 0.2.2, Datasette: 0.64.1, Python: 3.9.6, SQLite: 3.36.0 and when I open "Install and Manage Plugins", I get an Error 500 "'NoneType' object has no attribute 'day'"

Opening the server log shows this:

I have the same issue as @thomersch . I did the following adhoc change to the prettydate() function, which seems to have solved it. At least the plugin selection screen is shown now.

    try:
        return "{day}{suffix} {month} {year}".format(
            day=date.day,
            month=date.strftime("%B"),
            suffix=suffix(date.day),
            year=date.year,
        )
    except:
        return date

Same here. Installed the application, wanted to install a plugin and got the same error.

@havardgulldahl can you please give some more details on which file you made the change in. Where would I find that file on disk? Thanks.

@bigloudjeff That function (prettydate()) is in this file: /Users/<your username here>/.datasette-app/venv/lib/python3.9/site-packages/datasette_app_support/__init__.py. @havardgulldahl replaced the entire body of that function with the snippet.
