Depois de migrar meu Macbook para o novo, encontro um erro durante a reinstalação do rvm
⋊> rvm install 2.3.3
1.29.3 (master) por Michal Papis, Piotr Kuczynski 2.5.0p0
2.5.0
Instale o ruby 2.3.3 via rvm na perfeição.
Searching for binary rubies, this might take some time.
No binary rubies available for: osx/10.13/x86_64/ruby-2.3.3.
Continuing with compilation. Please read 'rvm help mount' to get more information on binary rubies.
Checking requirements for osx.
Certificates bundle '/usr/local/etc/openssl/cert.pem' is already up to date.
Requirements installation successful.

Eu enfrentei o mesmo problema depois de migrar meu Mac também (ambos MacOS High Sierra). Depois de correr
sudo mv /usr/local/include /usr/local/include_old
e depois
rvm install 2.5.0 --with-openssl-dir=/usr/local/opt/openssl/bin/openssl
as coisas começaram a funcionar normalmente.
