刚安装El Capitan，不能安装gem eventmachine 1.0.7。Openssl的版本是1.0.2a-1。尝试使用——with-ssl-dir，但似乎被忽略了。
报告到他们的github回购以及。
任何建议都非常感谢。谢谢。

注意:在我能够成功安装这个宝石之前，我必须做一些事情。这些可能适用于你，所以在这里列出它们-
1.)退出公司vpn
或者你可能不得不打开代理设置
2)。PKG_CONFIG_PATH设置为-
echo $PKG_CONFIG_PATH
/usr/local/opt/openssl/lib/pkgconfig
3.)必须在bash_profile中添加以下到$PATH(在我的情况下~/.zshrc)
export PATH="/usr/local/opt/openssl/bin:$PATH"
4)。另外请注意，与我在这篇SO帖子中得到的一些答案相反，以及github-eventmachine上的这个线程，我无法安装eventmachine
