This page contains various notes for myself and maybe something helpful for you.
Execute around, a way to use ruby blocks to execute boilerplate or helpful code without adding the code to a method. This helps when trying to log around a method without adding the logging code to the method itself.
RVM is plagued with various OS level issues so below are some fixes for OS X:
Autolibs is a feature built into RVM to allow you to automatically install dependencies on your system.From https://rvm.io/rvm/autolibs
» rvm install ruby-2.4.6 --with-openssl=/usr/local/opt/[email protected]/bin/openssl Warning, new version of rvm available '1.29.10-next', you are using older version '1.29.0'. You can disable this warning with: echo rvm_autoupdate_flag=0 >> ~/.rvmrc You can enable auto-update with: echo rvm_autoupdate_flag=2 >> ~/.rvmrc ruby-2.4.6 - #removing src/ruby-2.4.6 - please wait Checking requirements for rvm_pkg.

Halting the installation.
This breaks if RVM is trying to use autolibs, fix this by first enforcing homebrew as the package manager:
rvm autolibs homebrew
Then use your installation command, in my version:
rvm install ruby-2.4.6 --with-openssl-dir=
brew --prefix openssl
