Installing Rails on Fedora 20 Fails

Reid Cooper

I am having an issue getting Rails installed on Fedora 20 Linux. Ruby is installed without a problem:

$ ruby -v
ruby 2.0.0p353 (2013-11-22 revision 43784) [x86_64-linux]

But when I try to install Rails via this command:

sudo gem install rails -v 4.2.0.beta2

I get the following error.....

Here is the error - having some issues getting it to format correctly...

ERROR:  Error installing rails:

************************************************************************
IMPORTANT!  Nokogiri builds and uses a packaged version of libxml2.

If this is a concern for you and you want to use the system library
instead, abort this installation process and reinstall nokogiri as
follows:

	gem install nokogiri -- --use-system-libraries

If you are using Bundler, tell it to use the option:

	bundle config build.nokogiri --use-system-libraries
	bundle install

However, note that nokogiri does not necessarily support all versions
of libxml2.

For example, libxml2-2.9.0 and higher are currently known to be broken
and thus unsupported by nokogiri, due to compatibility problems and
XPath optimization bugs.

There we go. I had to trim some of the top bit off but all of the actual error is there now.

I gave up, at least for the moment, and just went with the production Rails 4.1.6 version which went in without a problem.
