Erro ao configurar

Pessoal, boa tarde! Todos os links dessa aula estão quebrados (Erro 404) e, segundo a documentação oficial, tenho deparado com vários erros. Ao reinstalar seguindo as orientações da aula, o mesmo erro acontece. Ao tentar emular o app, recebo o seguinte erro: http://prnt.sc/pnle7r

error React Native CLI uses autolinking for native dependencies, but the following modules are linked manually: 
  - react-native-navigation (to unlink run: "react-native unlink react-native-navigation")
This is likely happening when upgrading React Native from below 0.60 to 0.60 or above. Going forward, you can unlink this dependency via "react-native unlink <dependency>" and it will be included in your app automatically. If a library isn't compatible with autolinking, disregard this message and notify the library maintainers.

error Could not find the following native modules: ReactNativeNavigation. Did you forget to run "pod install" ?
info Found Xcode workspace "insta.xcworkspace"

Aguardo reposta. Obrigado!
