Error installing Rails

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

I advise using rvm to install ruby and rails https://rvm.io/

Colin

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!
