Hello,

I am trying to update my system to Rails 2. I followed the excellent  
instructions at Hivelogic to get rails running on my mac. However, I  
am getting a permissions error that I am unsure how to handle.

$ script/server  
Rails requires RubyGems \>= 0.9.4 (you have 0.9.2). Please `gem update --system` and try again.

$ gem update --system  
Updating RubyGems…  
Attempting remote update of rubygems-update  
ERROR: While executing gem … (Errno::EACCES)  
Permission denied - /usr/local/lib/ruby/gems/1.8/cache/rubygems-  
update-1.0.0.gem

Not sure how to change permissions on these library files, or if that  
is even what I should do! Can anyone give me guidance or assistance?

Thanks!

You need to run the process as administrator.

sudo gem update --system
