Error when installing Rails on Mac OSx 10.10 Yosemite

Question

I am trying to install Rails on my updated Mac OSx 10.10 Yosemite. I first used the command:

$ \curl -L https://get.rvm.io | bash -s stable --ruby=2.2.0

to install the latest RVM and Ruby versions. I also updated the gems using the command:

$ gem update --system

Until now everything looks OK but when I try to install the latest Rails version using the command:

$ gem install rails --version=4.2.0

I get this error message:

>   ERROR: Failed to build gem native extension.
    Buidling Nokogiri with a packaged version of libxml2-2.9.2
with the following patches applied:
    - 0001-Revert-Missing-initialization-for-the-catalog-module.patch
    - 0002-Fix-missing-entities-after-CVE-2014-3660-fix.patch

I tried installing Nokogiri, and retried the command but got the same error message.

Any suggestion?

There are several things here you can try:

Error to install Nokogiri on OSX 10.9 Maverick?

I don't use RVM, but also had trouble installing Nokogiri on a fresh Mavericks installation a while back and resolved it with one of the alternative answers farther down the page , using xcode-select --install .

Also note the accepted answer has updated instructions for Yosemite, so I'd check out all the answers for possible solutions.
