使用：Mountain Lion 10.8.2、RVM 1.18.15

、とのトラブルを持って明らかに、opensslRVMを経由してのRuby 2.0.0をインストールしようとすると：

$ rvm install 2.0.0
...
Extracting openssl to /Users/meltemi/.rvm/src/openssl-1.0.1c

Compiling openssl in /Users/meltemi/.rvm/src/openssl-1.0.1c.
Error running 'make', please read /Users/meltemi/.rvm/log/ruby-2.0.0-p0/openssl/make.log

それで、brew install opensslopensslを更新し1.0.1eて、それが役立つことを期待しますが、さらに多くのエラーがありました（「長い出力」を参照）。

それで、Stack Exchangeを掘り下げ、この投稿の提案に緩やかに従いrvm get head、（私の典型的なrvm get stableとは対照的に）推奨し、気づいた：

$ rvm get head

面白いビットcannot load such file -- opensslです。

何ができますか？

長い出力：

opensslをhomebrew経由で1.0.1.eに更新した後、再試行しましたが、何らかの理由で1.0.1cがまだ参照されています。

同じ問題があった。以下を試してください：

$ rvm remove 2.0.0 # get rid of unsuccessful installation
$ rvm get head --autolibs=3 # get the latest RVM and build required libs
$ rvm requirements # just in case, install all other required stuff
$ rvm install ruby-2.0.0
$ rvm --default use ruby-2.0.0

だからこれは私のために働きました：

rvm pkg install openssl
rvm reinstall all --force

rvm autolibs rvm_pkgreadlineのサポートも必要でした。
