Hey @ckeeney. Thank you for your interest in Theme UI.

You've added a peer dependency to workspace root package.json, which is a private package.
It contains the dependencies and scripts used to maintain the library.

If you're looking for one of theme-ui's proper package.json files, you can find them in packages/ directory.

However, I must say sorry — I shouldn't have labeled #2198 as good first issue — the work to do here is a bit more complex than modifying peerDependencies in a package.json. To close the issue, we'd need a TypeScript or Bash script, a GitHub action step that would verify we're installing without errors.
