我需要 Ruby 2.0.0，所以我求助于 RVM 来帮助管理我的 ruby 安装。
但是，当我这样做时rvm install ruby-2.0.0，安装最终会爆炸。
$ rvm install ruby-2.0.0
Searching for binary rubies, this might take some time.
No binary rubies available for: osx/10.12/x86_64/ruby-2.0.0-p648.
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.
Installing Ruby from source to: /Users/nick/.rvm/rubies/ruby-2.0.0-p648, this may take a while depending on your cpu(s)...
ruby-2.0.0-p648 - #downloading ruby-2.0.0-p648, …我继承了一个遗留代码库，需要使用 RVM 安装 Ruby 2.0.0。我使用的是 Mac OS X Catalina，Ruby 2.0.0 的安装程序根本不起作用。
以下是我的安装尝试，从 RVM 本身的安装一直到尝试安装 Ruby 2.0.0。
