I updated an artifact online and wanted therefore to remove the existing (old) artifact I had locally, so I went and found the folder that contained it (in `.julia/artifacts/hash/here`) and just deleted it. Now I get this error:

```

How can I fix this?

Not knowing how Julia tracks all the stuff in the `.julia` directory I would probably nuke the whole `.julia` directory and let it be rebuilt.

I can’t find this package anywhere (not registered, not known to Google), so it’s hard to diagnose this. It looks like `bind_artifact!` is complaining that there’s already an entry for the name you’re giving to that artifact. You have to use `unbind_artifact!()` to remove the existing binding or equivalently, manually delete the stanzas in the `Artifacts.toml` file that define that artifact binding.

Thanks for trying!

I’ll try what you suggested.
