Recently I decided to clear out my RVM environments and start fresh. I’m running on a Snow Leopard MacBook Air. Here are the steps I went through.
$ curl -O ftp://ftp.cwru.edu/pub/bash/readline-6.0.tar.gz $ tar xvf readline-6.0.tar.gz $ cd readline-6.0 $ ./config && make && sudo make install $ cd .. $ rm -rf $HOME/.rvm $ bash < <(curl -s https://rvm.beginrescueend.com/install/rvm) $ rvm install 1.8.7 -C --with-arch=x86_64, --with-readline-dir=/usr/local $ rvm system $ rvm gemset export system.gems $ rvm 1.8.7 $ rvm gemset import system $ rvm --default 1.8.7
The following pages were helpful in figuring this out.
