Erro ao instalar o psycopg2 e o psycopg2-binary
Oi Luiz, parece ser um erro de conexão. Outras bibliotecas estão sendo instaladas normalmente? Já verificou se o seu editor não foi bloqueado pelo firewall? De qualquer forma, outra opção é baixar a biblioteca na documentação e fazer a instalação manual, caso esteja utilizando o PyCharm é possível instalar pela interface da IDE.
