Hi guys I'm a Rails virgin. I'm pulling my hair out with the install. So far, I've checked that I've got Ruby & Gems, see below; Pauls-iMac:~ pauldoran$ ruby --version ruby 1.8.7 (2012-02-08 patchlevel 358) [universal-darwin12.0] Pauls-iMac:~ pauldoran$ gem --version 1.3.6 I'm trying to install Rails as follows; Pauls-iMac:~ pauldoran$ sudo gem install rails But get the following error message; ERROR: Error installing rails: ERROR: Failed to build gem native extension. /System/Library/Frameworks/Ruby.framework/Versions/1.8/usr/bin/ruby extconf.rb mkmf.rb can't find header files for ruby at /System/Library/Frameworks/Ruby.framework/Versions/1.8/usr/lib/ruby/ruby.h Gem files will remain installed in /Library/Ruby/Gems/1.8/gems/json-1.7.6 for inspection. Results logged to /Library/Ruby/Gems/1.8/gems/json-1.7.6/ext/json/ext/generator/gem_make.out I've read the forum for similar errors but non of the fixes seem to work. Any help would be so appreciated.

This can be related you your Mac's XCode issue. The main cause which I can remind, may be you end up having more than one XCode versions or your system is messed up. Re-installing you XCode should resolve your problem

First, install rbenv/ruby-build or RVM https://github.com/sstephenson/rbenv/ https://github.com/sstephenson/ruby-build or https://rvm.io/ Then install ruby 1.9.3 Then install rails Good luck! Den tisdagen den 5:e februari 2013 kl. 08:37:23 UTC+1 skrev Ruby-Forum.com User:
