Answer 1

You have to install OpenSSL first and recompile ruby again:

RVM:

rvm pkg install openssl
rvm reinstall ruby-2.0.0-p0 --with-gcc=gcc-4.7 --with-openssl-dir=$rvm_path/usr

Answer 2

I fix this error for ruby 2.1.2 as follow.

rvm pkg install openssl
rvm reinstall ruby-2.1.2 --with-openssl-dir=$rvm_path/usr

Answer 3

When installing ruby 2.0, it is possible that rubygems 2.0 installation did not complete ok, because of openssl. Make sure you provide a valid path to the openssl config file; you could:

find . -type f -name "openssl.cnf"

path is usually $HOME/.rvm/usr or $HOME/.rvm/usr/ssl

Then

[sudo] rvm reinstall ruby-2.0.0-p0 --with-openssl-dir=[openssl.cnf path] --verify-downloads 1

Make sure rubygems installation complete successfully. Might be a better way to fix that path without reinstalling, but this should do it.

Answer 4

If you are using ruby-install, it will take the same openssl argument as rvm:

ruby-install ruby-2.0.0-p247 -- --with-openssl-dir=/usr/local/opt/openssl

Answer 5

I had the same problem with the same OS version. I use rvm and followed the steps in this command:

$ rvm requirements

Following those instructions, I ran:

$ brew update
$ brew tap homebrew/dupes
$ brew install bash curl git
$ brew install autoconf automake apple-gcc42 libtool pkg-config openssl readline libyaml sqlite libxml2 libxslt libksba

Answer 6

On OSX, with rbenv and homebrew, the following worked for me:

brew install openssl
CONFIGURE_OPTS=--with-openssl-dir=$(brew --prefix openssl) rbenv install whatever-ruby-version
