在我的EC2 redhat实例上，我正在尝试使用gem安装httparty。
在下面的网站上，我添加了repo并安装了ruby193。
http://developerblog.redhat.com/2013/01/28/software-collections-on-red-hat-enterprise-linux/
是的，我在/ usr / bin创建了ruby和gem的软链接，并在/etc/ld.so.conf.d/中创建了conf文件并运行了ldconfig。
现在，当我尝试安装时，我遇到了错误。
gem install httparty json

做了一些谷歌搜索，发现我需要安装ruby-devel。得到rpm并尝试安装我现在得到以下错误。

You could try using --skip-broken to work around the problem
You could try running: rpm -Va --nofiles --nodigest
我知道它抱怨ruby1.9，但我已经安装了它。
答案 0 :(得分：0)
我找到了解决方案：
我在yum找到了devel包，它的名字不同。
yum install ruby193_devel
