Antes de limpar o cache
npm cache clear
npm está funcionando bem. Depois de limpar o cache, ele não está funcionando. O log de erros abaixo sugere um problema com a conectividade com a Internet, mas a conexão com a Internet está OK. Este problema não acontece apenas com o bower, mas com todos os módulos.
Aqui está o resultado do processo:
