Issue

Hyper occasionally returns the following error (previewed in a macOS notification):

error An unexpected error occurred: "ENOTEMPTY: directory not empty, rmdir '/Users/jschuur/.hyper_plugins/node_modules/electron/dist/Electron.app/Contents/Resources'".

I don't know what is trying to delete that directory, but it doesn't sound safe to do so, since it's related to Electron. I can't trigger this error specifically, it just crops up at seemingly random a few times a day.

How do I clean this up and stop the notification?

I did un/install a few plugins through two different methods: by editing the config file directly, and by using the CLI. Maybe something got mixed up when it was trying to do cleanup after I uninstalled some?

Start with the linked gist and the Electron.app path in .hyper_plugins/node_modules, then review the two plugin-management entry points mentioned: direct config edits and the CLI. Reproduce the uninstall and cleanup flow on macOS; done means identifying why the ENOTEMPTY notification occurs and preventing the recurring error.
