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/lib/ruby/gems/1.8/gems/rails-2.0.2/lib/initializer.rb:88:in `process'        from /usr/lib/ruby/gems/1.8/gems/rails-2.0.2/lib/initializer.rb:49:in `send'        from /usr/lib/ruby/gems/1.8/gems/rails-2.0.2/lib/initializer.rb:49:in `run'        from /home/simon/dev/depot/config/environment.rb:13        from /usr/local/lib/site_ruby/1.8/rubygems/custom_require.rb:27:in `gem_original_require'        from /usr/local/lib/site_ruby/1.8/rubygems/custom_require.rb:27:in `require'        from /usr/lib/ruby/gems/1.8/gems/activesupport-2.0.2/lib/active_support/dependencies.rb:496:in `require'        from /usr/lib/ruby/gems/1.8/gems/activesupport-2.0.2/lib/active_support/dependencies.rb:342:in `new_constants_in'         ... 7 levels...        from /usr/lib/ruby/gems/1.8/gems/rails-2.0.2/lib/commands/server.rb:39        from /usr/local/lib/site_ruby/1.8/rubygems/custom_require.rb:27:in `gem_original_require'        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-rubyruby1.8 - Interpreter of object-oriented scripting language Ruby 1.8libopenssl-ruby - OpenSSL interface for Rubylibopenssl-ruby1.8 - OpenSSL interface for Ruby 1.8libopenssl-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。
