como você pode ver, várias gemas, como essa
minitest (5.10.1, 5.8.4, 5.5.1, default: 4.3.2)
tem várias versões instaladas e esse default está apontando para as versões mais antigas.
Eu quero excluir todas essas versões, mantendo apenas a mais recente e atribuindo o padrão a essa última. sudo gem cleanup ou mesmo sudo gem cleanup rjb não está fazendo isso.
Alguma sugestão? obrigado.
