OpenSSL error installing ruby 2.0.0-p195 on Mac with rbenv

Question

I'm trying to install Ruby 2.0.0-p195 using rbenv on a Mac (Mountain Lion) and got this error.

The Ruby openssl extension was not compiled. Missing the OpenSSL lib?

When I ran brew install openssl it said

Warning: openssl-1.0.1e already installed

Following a solution on this thread https://github.com/sstephenson/ruby-build/issues/305 I tried to install latest stable this way and got the same error

env CFLAGS='-g -O2' RUBY_CONFIGURE_OPTS="--with-readline-dir=`brew --prefix readline`" rbenv install 2.0.0-p195

Any ideas?

Answer 1

Try adding OpenSSL to the config options using the --with-openssl-dir option:

$ CONFIGURE_OPTS="--with-openssl-dir=`brew --prefix openssl`" rbenv install 2.0.0-p195

If you're using Homebrew, you'll need to install OpenSSL before running the above by running:

$ brew install openssl

UPDATE (see @JarkkoLaine 's comment below):

Just for the record, you should not need to use the config opts anymore with ruby-build and homebrew. However, I had to reinstall openssl with homebrew to make it work: brew uninstall openssl; brew upgrade; brew install openssl; rbenv install 2.0.0-p247. See this for more info.
