ZSH -> RVM

install RVM

Fiddle with your .bash_profile (I can send you what you need if you don’t already have it)

run the following stuff in order:
rvm requirements
rvm pkg install readline
rvm pkg install iconv
rvm pkg install zlib
rvm pkg install openssl
rvm pkg install autoconf
rvm pkg install curl
rvm pkg install gettext
rvm pkg install glib
rvm pkg install libxml2
rvm pkg install libxslt
rvm pkg install libyaml
rvm pkg install llvm
rvm pkg install mono
rvm pkg install ncurses
rvm pkg install pkgconfig

and finally

rvm install 2.3.1


rvm package install is deprecated but it ensures you have those libraries installed on your machine (not all gems require them, which is why they are optional and not installed by default)


if you ever install a package, you’ll need to re-install ruby through rvm to allow it to use it

rvm reinstall 2.3.1
