Hi, I am new in mac and ruby on rails, please bear with me if I asked stupid questions :

I tried to install, rails in my mac :"

bdelmajids-iMac:~ majid$ gem install rails ERROR: While executing gem ... (Gem::FilePermissionError)     You don't have write permissions for the /Library/Ruby/Gems/1.8 directory. Abdelmajids-iMac:~ majid$

Please your help is appreciated. thanks,

From the looks of it, you're trying to install rails system-wide with that. If that's what you want, preceed the gem command with sudo.

A possibly better alternative is to install either rvm or rbenv, and have things loaded per user or per project.

The samething happened when I try : sudo gem install rails
