no such file to load -- openssl (RuntimeError)

今天更新了Rails到2.0.2版本，启动application时出现了一下错误：

=> Booting WEBrick...
/usr/lib/ruby/gems/1.8/gems/rails-2.0.2/lib/initializer.rb:159:in `require_frameworks': no such file to load -- openssl (RuntimeError)

        from /usr/local/lib/site_ruby/1.8/rubygems/custom_require.rb:27:in `require'
        from script/server:3

一开始还以为自己没有安装 openssl, 一查已经 安装过openssl，原来是少安装了libopenssl-ruby

simon@simon-laptop:~$ sudo apt-cache search libopenssl-ruby
ruby1.8 - Interpreter of object-oriented scripting language Ruby 1.8
libopenssl-ruby - OpenSSL interface for Ruby
libopenssl-ruby1.8 - OpenSSL interface for Ruby 1.8
libopenssl-ruby1.9 - OpenSSL interface for Ruby 1.9

我使用的是ruby1.8，所以就 sudo apt-get install libopenssl-ruby1.8
然后重启应用，问题解决。

我今天也碰到这个问题，按楼主的方法完美解决了。
话说那个错误提示误人不少，我一开始也是以为没有安装openssl的ruby库。

Solaris下也必须安装openssl with ruby

Solaris该怎么装？

Same problem with you.
After update rails to 2.0.2, i get the same exception with you when i run script/server.

I do same with you, but also failed. Any other method to resolve this problem?
Thx.
