After I have changed my debian server from rvm to use rbenv I gave it a shot for my local system: These commands should work: git clone https://github.com/sstephenson/rbenv.git ~/.rbenv echo 'export PATH="$HOME/.rbenv/bin:$PATH"' >> ~/.bashrc echo 'eval "$(rbenv init -)"' >> ~/.bashrc " type rbenv" should show something like "rbenv is a function" git clone https://github.com/sstephenson/ruby-build.git ~/.rbenv/plugins/ruby-build git clone https://github.com/sstephenson/rbenv-gem-rehash.git ~/.rbenv/plugins/rbenv-gem-rehash rbenv install 2.1.1 -k rbenv global 2.1.1 gem install rails But unfortunately first ruby and then rails were not working as good on manjaro/arch as on debian. So I had to find solutions: CONFIGURE_OPTS="--with-readline-dir=/usr/include/readline" rbenv install 2.1.1 OR (could not get console working, tried following) curl -fsSL https://gist.github.com/mislav/a18b9d7f0d...
