Eu instalei rbenv do GitHub:
git clone git://github.com/sstephenson/rbenv.git ~/.rbenv
git clone git://github.com/sstephenson/ruby-build.git ~/.rbenv/plugins/ruby-build
Estou tentando instalar o Ruby 2.2.0:
sudo /home/vagrant/.rbenv/bin/rbenv install 2.2.0
Como posso corrigir isso?
Aqui estão as últimas linhas do log:
