I'm on a fresh Ubuntu installation and using the guide to install rails found here.
When I get to the final sudo gem install rails, I get this error:

RubyGems 2.4.1 will not build native extensions in Ruby version 1.9.3 and earlier on Windows.
You will need to downgrade RubyGems to 1.8.29.
To do this run the following command:
gem update --system 1.8.29
Check gem version:
gem -v
1.8.29
Now try your command again:
gem install --local json-1.8.1.gem

I know this is one of the problem everybody is having these days and many of them have found ways to troubleshoot this problem. Unfortunately I have tried all the solutions but none of them seem to work on my system.
when I do
gem install linecache19
I get this error, as below
gem install linecache19

Use debugger-linecache, it's just an updated working fork of linecache19. You won't have installation issues like the one you are having because it's not built as a C extension anymore, it's 100% ruby.
gem install debugger-linecache
Hope it helps.

First install the Command Line Tools in the latest Xcode-Version.
and then run sudo gem install rails
To install Command Line Tools, go to XCode Preferences > Downloads.
On Ruby 1.8.7 and rails 2.3.5 I get:
gem install rmagick

on Ubuntu/Debian you would need to install:
sudo apt-get install libmagickwand-dev
on RedHat/Fedora/CentOS:
yum install ImageMagick-devel
To install rmagick with the gem system, you must have "imagemagick" on your system. The following error line says that rmagick failed to build because the native extension (imagemagick) does not exist on your system.
ERROR: Failed to build gem native extension.
On OSX, you can use brew (the best way in my opinion) to install imagemagick. Once brew is installed :
brew install imagemagick
gem install rmagick
On Mountain Lion (OSX), after:
brew install imagemagick
it may be necessary to force the re-creation of some symlinks manually before being able to install the rmagick gem.
> brew link -f jpeg
> brew link -f libpng
> brew link -f freetype
> brew link -f imagemagick
On fedora make sure you have ImageMagick-devel installed.
