Installs 2.1.1 on ubuntu via checkinstall so it's in your package manager and you can remove it.
Quick install:
curl -L https://gist.github.com/denji/5760269/raw/ruby-2-install-ubuntu.sh | bash -s
#!/usr/bin/env bash | |
set -e | |
sudo apt-get build-dep ruby1.9.1 | |
wget -c http://ftp.ruby-lang.org/pub/ruby/2.1/ruby-2.1.1.tar.gz | |
tar xzf ruby-2.1.1.tar.gz | |
cd ruby-2.1.1 | |
./configure | |
make | |
sudo checkinstall -y \ | |
--pkgversion 2.1.1 \ | |
--provides "ruby-interpreter" |
Wont work since the folder will be ruby-2.1.0
