我安装了 Ubuntu 10.04，然后将其升级到 12.04。从那里我按照本教程设置 RoR： http ://ryanbigg.com/2010/12/ubuntu-ruby-rvm-rails-and-you/
然而，我在这里是因为我已经花了超过 12 个小时与不同的错误消息作斗争，并且想开枪打人。
错误一：
greg2@greg-desktop:~/bballApp$ ruby -v
ruby 1.8.7 (2011-06-30 patchlevel 352) [i686-linux]
greg2@greg-desktop:~/bballApp$ rails -v

错误2：
greg2@greg-desktop:~/bballApp$ bundle install
Your Ruby version is 1.8.7, but your Gemfile specified 1.9.3
所以，谷歌告诉我查看我的 .zshrc 文件并添加：
[[ -s "$HOME/.rvm/scripts/rvm" ]] && . "$HOME/.rvm/scripts/rvm"
我然后做了。
返回并得到相同的错误。所以我尝试了：
greg2@greg-desktop:~/bballApp$ rvm list
rvm rubies
ruby-1.9.3-p194 [ i686 ]
=* ruby-1.9.3-p362 [ i686 ]
我正在和一个在 MAC 上运行它的朋友一起开发它。
