Hey @ndmitchell, I think we need a new release again, because I'm getting this error with nightly:

   Compiling starlark v0.5.0

error: could not compile `starlark` due to 2 previous errors

For now, I fixed this problem adding starlark with git path to the dependencies list. Thanks.

The issue is a newer anyhow release broke the anyhow! formatting strings. I'll make a new release on Monday.
