Esse erro acontece devido a versão antiga do npm que o professor pede para instalar: npm install -g @angular/cli@10.1.6
Se você desinstalar ele: npm uninstall -g @angular/cli
Limpar o cache: npm cache clean --force
Instalar a ultima versão: npm install -g @angular/cli
Ele vai funcionar normalmente nas próximas etapas.
