Ho installato ruby via rbenv e rbenv-build. Ho impostato la versione di ruby globalmente, localmente (nella directory locale dove ho installato wordpress) e nella shell corrente (dal percorso della directory locale dove ho installato wordpress):
Ottengo questo errore:
An exception occurred running /Users/nonchiedercilaparola/.rbenv/versions/rbx-2.2.10/bin/wordmove:
