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

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。
