Installation

Note: MRI requires OpenSSL >= 1.0.1.

wget http://cache.ruby-lang.org/pub/ruby/2.4/ruby-2.4.0.tar.bz2
tar -xjvf ruby-2.4.0.tar.bz2
cd ruby-2.4.0
./configure --prefix=/opt/rubies/ruby-2.4.0
make
sudo make install

Note: OS X users must update their OpenSSL CA cert bundle and properly set ./configure --with-opt-dir to compile against Homebrew's libraries:

wget http://cache.ruby-lang.org/pub/ruby/2.3/ruby-2.4.0.tar.bz2
tar -xjvf ruby-2.4.0.tar.bz2
cd ruby-2.4.0
./configure --prefix="$HOME/.rubies/ruby-2.4.0" --with-opt-dir="$(brew --prefix openssl):$(brew --prefix readline):$(brew --prefix libyaml):$(brew --prefix gdbm):$(brew --prefix libffi)"
make
make install
