当我运行'update gems'时，我收到以下警告：
WARNING: Installing to ~/.gem since /Library/Ruby/Gems/1.8 and
/usr/bin aren't both writable.
WARNING: You don't have /Users/azamsharp/.gem/ruby/1.8/bin in your PATH,
gem executables will not run.
Building native extensions. This could take a while...
出于某种原因，我认为这与我目前尚未解决的其他更大的错误有关，并且有200点的开放奖励。 Trouble Getting the Rails Server Started
谢谢，
