Description
@react-native/jest fails to resolve react-native in monorepos that use pnpm or Yarn in pnpm mode. @react-native/jest makes direct references to react-native but never declares it as a dependency, hence it cannot find it because the package manager will never install it.
I was going to add react-native as a peer dependency but it looks like this will create a cycle since react-native has a peer dependency on @react-native/jest. Not sure what approach you would prefer here.
This is the workaround we're currently using: https://github.com/microsoft/rnx-kit/blob/18bf2c4c307826d8d075351d1b8aa93387566177/.yarnrc.yml#L37-L40
Steps to reproduce
- Clone https://github.com/microsoft/rnx-kit
- Remove the workaround mentioned above
- Run
yarn
- Build dependencies leading up to the test app:
yarn build-scope @rnx-kit/test-app
- Run test:
cd packages/test-app; yarn test
