Looks like some files ended up in the wrong place in a recent PR. I'm looking into it.

For WebPack users (as the compiler suggests) adding a resolve fallback to the 'path' package temporarily fixes the issue:

 resolve: {
    extensions: ['.js', '.jsx', '.ts', '.tsx', '.json'],
    fallback: { 'path': false },
  },
