我试图在Ubuntu服务器上设置Ruby on Rails。只要找到有效版本的红宝石，我就不在乎哪个版本的红宝石，但我正在使用v2.1.0。每当我尝试运行任何sudo gem ...命令时，我都会收到以下错误：
ERROR: Loading command: install (LoadError)
cannot load such file -- openssl
ERROR: While executing gem ... (NoMethodError)
undefined method `invoke_with_build_args' for nil:NilClass
我认为我只需要安装openssl，但是当我使用rvm pkg install openssl进行尝试时，它会运行一段时间，但之后会失败并提供以下输出：

Please note that it's required to reinstall all rubies:
rvm reinstall all --force
Updating openssl certificates..
我的系统上已经准备好了几个openssl目录，并且我已经尝试使用指向每个的--use-openssl-dir等参数重新安装ruby几次，但我仍然得到完全相同的错误显示在顶部这个帖子。我确定我必须以某种方式让rvm pkg install openssl工作。任何见解都将不胜感激。
更新嗯，我刚刚修改了我的ruby版本并再次安装了它，现在工作正常。
