[3:12 PM] i had to manually remove heroku--kafka from ~/.local/share/heroku/plugins/package.json

[jdx]

from @fnando

[jdx]

this happens because we add the plugin to package.json, then attempt to install. We could either add a ctrl-c hook or somehow know that the installation wasn't successful and remove it instead of attempting to repair later

[jdx]

a related problem that should also be resolved: if some kind of error is causing plugins:uninstall to fail it can't continue to uninstall the plugin
