A pagina não carrega as alterações ao atualizar, tenho que reiniciar o servidor, e qd reinicio da esse erro e não carrega a pagina, ai tenho que atualizar a pagina para aparecer o conteudo.

Eder, boa tarde!

Esses não são erros e sim avisos, o seu código está funcionando normalmente.

Caso você queira retirar esses avisos é necessário retirar os atributos href das tags dentro do seu render.

Espero ter ajudado e bons estudos!

Ok, e quanto a ter que reiniciar o servidor toda vez para atualizar a pagina alguma sugestão?

Eder, boa tarde!

CHOKIDAR_USEPOLLING=true npm start

Se parou de dar reload pode ser porque o número de watchers que o sistema operacional libera pros arquivos atingiu o limite, ai o webpack não consegue detectar as mudanças e trava o live reload

Além disso, parar os processos reiniciando o computador irá ajudar!

Espero ter ajudado e bons estudos!
