not able to install ruby on rails in OSX mavericks

Question

I have OSX mavericks and I was trying to install ruby on rails .First I tried Installing via RailsInstaller ( http://railsinstaller.org/en ) ,There was a notice in the website saying "Please do not run the installer on OSX Mavericks until further notice."

Then I tried installing using rvm which turned out to be a night mare .

I followed instructions from all the below links none seem to work

Installing Rails on Mavericks

Xcode install on OSX 10.9 - clang: error: no input files

Installing Rails on Mavericks

http://railsapps.github.io/installrubyonrails-mac.html

I have installed Xcode 5.0 and I have even manually downloaded Command lines tools

https://developer.apple.com/downloads/index.action

when I try

rails -v

I get a message

Rails is not currently installed on this system. To get the latest version, simply type:

$ sudo gem install rails

Then I tried command for which I got an error message

Building native extensions.  This could take a while... ERROR:  Error installing rails:     ERROR: Failed to build gem native extension.

    /System/Library/Frameworks/Ruby.framework/Versions/2.0/usr/bin/ruby extconf.rb checking for libkern/OSAtomic.h... yes creating Makefile

    if (OSAtomicCompareAndSwap64(expect_value, new_value, &DATA_PTR(self))) {
                                                          ^~~~~~~~~~~~~~~ /usr/include/libkern/OSAtomic.h:507:93: note: passing argument to parameter '__theValue' here

I'm not able to use xcode-select --install either which says the software is not present in the server

Please guide on how to install rails on my osx mavericks ?

Answer 1

Rails 4 needs RubyGems 2.0.3. Update it and you should be good to go.

gem update --system 2.0.3

Then,

gem install rails

Hope it helps.
