当我尝试使用bundler 时，出现错误：
/home/vivek/.rvm/rubies/ruby-1.9.3-p194/lib/ruby/site_ruby/1.9.1/rubygems/custom_require.rb:36:in `require': 无法加载此类文件 -- openssl (LoadError )
完整的错误消息如下。我该如何解决？

以下教程建议使用 SSL 支持重新编译 Ruby：http : //www.dinduks.com/rails-cannot-load-such-file-openssl
假设您使用 RVM，以下是解决此问题的步骤。
安装 openssl 包
rvm pkg install openssl
删除您正在使用的 Ruby 安装
rvm remove 1.9.3
最后用openssl重新编译Ruby
rvm install 1.9.3 --with-openssl-dir=$HOME/.rvm/usr
现在一切都应该正常了。不要忘记：
rvm use 1.9.3 --default
这里有一些更多的链接，它们基本上建议做同样的事情：
