Estou a um bom tempo tentando corrigir um erro que esta ocorrendo na classe PhotoService. Ocorre no decorator @Injectable({ providedIn: 'root' } ), não aceita o argumento { providedIn: 'root' } . Erro: Expected 0 arguments, but got 1.ts(2554)

Erro no @Injectable({ providedIn: 'root' } )
Boa tarde, Cristiano! Como vai?
Qual a versão do Angular que vc está utilizando? Para fazer essa verificação, execute o comando ng version. Depois, cole aqui, por favor, o resultado desse comando e o conteúdo completo do arquivo package.json do seu projeto para que eu possa dar uma olhada e tentar te ajudar!
Qualquer coisa é só falar!
Grande abraço e bons estudos, meu aluno!
Comando: C:\Users\Cris\alurapic>ng version Your global Angular CLI version (8.3.4) is greater than your local version (1.7.4). The local Angular CLI version is used.
To disable this warning use "ng config -g cli.warnings.versionMismatch false".
