Bom, já fiz de tudo que o pessoal comentou no forum, estou desde quinta feira tentando começar o projeto e, semper paro em alguma coisa.
Dessa vez, finalmente consegui iniciar o projeto e logo de cara, na hora de importar o Router no index.js do src, ele deu um erro. Tentei corrigir e agora estou recebendo esse erro:
Attempted import error: 'Switch' is not exported from 'react-router-dom' (imported as 'Switch').
ERROR in ./src/routes.js 9:35-41

Infelizmente nada da certo, minha assinatura da alura faz 1 ano amanhã e estou arrependido de ter renovado...
