Heroku 登录/安装问题 (Ubuntu 12.04)

Question

我尝试在我的系统（64 位 ubuntu 12.04）上安装 heroku，但在实际安装时它没有抛出任何错误。 但是，当我尝试heroku登录时，出现此错误：

/usr/lib/ruby/1.8/x86_64-linux/readline.so: libreadline.so.5: cannot open shared object file: No such file or directory - /usr/lib/ruby/1.8/x86_64-linux/readline.so (LoadError)
    from /usr/lib/ruby/vendor_ruby/1.8/rubygems/custom_require.rb:36:in `require'
    from /var/lib/gems/1.8/gems/heroku-2.31.4/lib/heroku/command/run.rb:1
    from /usr/lib/ruby/vendor_ruby/1.8/rubygems/custom_require.rb:36:in `gem_original_require'

    from /var/lib/gems/1.8/gems/heroku-2.31.4/lib/heroku/command.rb:13:in `each'
    from /var/lib/gems/1.8/gems/heroku-2.31.4/lib/heroku/command.rb:13:in `load'
    from /var/lib/gems/1.8/gems/heroku-2.31.4/lib/heroku/cli.rb:27:in `start'

    from /usr/local/bin/heroku:19:in `load'
    from /usr/local/bin/heroku:19

有什么想法吗？
