Rails/ Nokogiri installation errors on Yosemite

After upgrading my Macbook air to Yosemite, I haven't been able to install rails. There's been a whole train of errors, and some of them I've been able to resolve. The current error, which I've been working unsuccessfully for days to resolve, looks like this 

naomi$ sudo gem install rails
Password:

ERROR:  Error installing rails:

I'm running OSX 10.10.2, and ruby -v gives me

ruby 2.2.1p85 (2015-02-26 revision 49769) [x86_64-darwin14]

Note: this may seem like a duplicate, but I believe it's not: I've been investigating solutions suggested on SO and elsewhere for days, and the posted solutions haven't resolved the error. Xcode is installed, with developer tools, so xcode-select --install gives me 

xcode-select: error: command line tools are already installed, use "Software Update" to install updates

Many thanks in advance for your help!

The Problem

For some reason Apple’s Yosemite version of OSX does not have a system accessible installation of libxml2. Nokogiri requires this in order to compile and luckily Xcode has a version of libxml2 bundled with it — we just need to specify it when installing the gem. It’s important to get Nokogiri installed correctly because as of right now Rails 4.2.1.rc4 automatically attempts to install it and you will feel pain.

The Fix

gem install nokogiri -- --use-system-libraries=true --with-xml2-include=/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.10.sdk/usr/include/libxml2

I found a related issue (the very last post) on Nokogiri's site.They solved the problem with:

sudo gem install nokogiri -- --with-xml2-include=/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.‌​platform/Developer/SDKs/MacOSX10.10.sdk/usr/include/libxml2 --use-system-libraries
