ruby-on-rails - 使用ruby 1.9.2，rails3.1.0，为什么我尝试生成脚手架时出错。

Question

基本上，当我尝试生成一个脚手架时，我收到了这个错误没有要加载的文件 -- openssl (LoadError)。错误来自

.rvm/gems/ruby-1.9.2-p290@rails310/gems/activesupport-3.1.0/lib/active_support/dependencies.rb:240:in `block in require'

不知道为什么会这样。这是完整的错误:

好吧，我最后做的是这个。

• 从 rvm 卸载所有版本的 ruby​​
• 从 rvm 中删除了所有的 gemset
• $ rvm pkg 安装 openssl
• $ rvm pkg 安装 zlib
• $ rvm install 1.9.2 --with-openssl-dir=$HOME/.rvm/usr --with-zlib-dir=$rvm_path/usr
• 在 gemset 中重新安装了 rails

之后一切正常。
