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
Please your help is appreciated.
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
I have rvm installed, how should I use it ?
gem install rails --version=4.0.0.rc1
version what ever you want
