You have to install OpenSSL first and recompile ruby again:
您必须先安装 OpenSSL 并再次重新编译 ruby：
RVM:
RVM：
rvm pkg install openssl
rvm reinstall ruby-2.0.0-p0 --with-gcc=gcc-4.7 --with-openssl-dir=$rvm_path/usr

If you're using RVM please follow:
如果您使用的是 RVM，请遵循：
$ brew install automake

Make sure you have installed OpenSSL first BEFORE installing ruby.

Uninstall rvm
rvm implode

or
或者
rm -rf ~/.rvm
Don't forget to remove the script calls in your .bashrc and/or .bash_profile (or whatever shell you're using). sudo apt-get install zlib1g zlib1g-dev build-essential openssl libssl-dev libmysqlclient18 libmysqlclient-dev libyaml-dev curl git-core python-software-properties libpq-dev nodejs
不要忘记删除 .bashrc 和/或 .bash_profile（或您使用的任何 shell）中的脚本调用。sudo apt-get install zlib1g zlib1g-dev build-essential openssl libssl-dev libmysqlclient18 libmysqlclient-dev libyaml-dev curl git-core python-software-properties libpq-dev nodejs
Then install RVM, post ruby.
然后安装 RVM，发布 ruby。
OR
或者
rvm pkg install openssl
rvm reinstall ruby-2.0.0-p0 --with-gcc=gcc-4.7 --with-openssl-dir=$rvm_path/usr
WITHOUT RVM
没有 RVM
First you should find where Ruby is:
首先，您应该找到 Ruby 的位置：
whereis ruby
will list all the places where it exists on your system, then you can remove all them explicitly. Or you can use something like this:
将列出它在您的系统上存在的所有位置，然后您可以明确删除所有这些位置。或者你可以使用这样的东西：
rm -rf /usr/local/lib/ruby
rm -rf /usr/lib/ruby
rm -f /usr/local/bin/ruby
rm -f /usr/bin/ruby
rm -f /usr/local/bin/irb
rm -f /usr/bin/irb
rm -f /usr/local/bin/gem
rm -f /usr/bin/gem
THEN
然后
sudo apt-get install zlib1g zlib1g-dev build-essential openssl libssl-dev libmysqlclient18 libmysqlclient-dev libyaml-dev curl git-core python-software-properties libpq-dev nodejs
apt-get -y update
apt-get -y install build-essential zlib1g-dev libssl-dev libreadline6-dev libyaml-dev
cd /tmp
wget http://cache.ruby-lang.org/pub/ruby/2.0/ruby-2.0.0-p247.tar.gz
tar -xvzf ruby-2.0.0-p247.tar.gz
cd ruby-2.0.0-p247/
./configure --prefix=/usr/local
make
make install
I hope this help you.

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

I had the same problem earlier, tried all of the snippets about and none of them worked out. After looking around for a bit the following worked for me:
我早些时候遇到了同样的问题，尝试了所有的片段，但没有一个成功。环顾四周后，以下对我有用：
$ 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
What does rvm get head --autolibs=3do exactly? I'm guess it automatically downloads dependencies, but I was hoping for a clear answer.
具体有什么作用rvm get head --autolibs=3？我猜它会自动下载依赖项，但我希望得到一个明确的答案。

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

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:
安装 ruby 2.0 时，可能是因为 openssl 导致 rubygems 2.0 安装没有完成。确保您提供了 openssl 配置文件的有效路径；你可以：
find . -type f -name "openssl.cnf"
path is usually $HOME/.rvm/usr or $HOME/.rvm/usr/ssl
路径通常是 $HOME/.rvm/usr 或 $HOME/.rvm/usr/ssl
Then
然后
[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.
确保 rubygems 安装成功完成。可能是在不重新安装的情况下修复该路径的更好方法，但这应该可以。

I encountered the same openssl error on Fedora when trying to use gem install <package>. It seems you need to install additional packages with yum/dnf
我在 Fedora 上尝试使用gem install <package>. 看来您需要使用 yum/dnf 安装其他软件包
sudo dnf install rubygems rubygem-bundler ruby-devel mariadb-devel
After running the above command, gem install <package>should now work.
运行上述命令后，gem install <package>现在应该可以工作了。
