/usr/local/rvm/rubies/ruby-1.9.3-p194/lib/ruby/1.9.1/mkmf.rb:381:in `try_do': 
The compiler failed to generate an executable file. (RuntimeError)
You have to install development tools first.

I have installed ruby 1.9.3 using RVM on my CentOS 6.2 server. When I try to run gem install nokogiri it produces the the output below. I have already visited the nokogiri website and installed the libxml2 and libxslt dependencies using yum: 

sudo yum install -y gcc ruby-devel libxml2 libxml2-devel libxslt libxslt-devel

I have also installed the libxml2 and libxslt packages using rvm pkg install and reinstalled ruby afterward.

I have been searching for a solution, but I haven’t found anything yet. Any ideas would be appreciated 🙂

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

Could not create Makefile due to some reason, probably lack of
necessary libraries and/or headers.  Check the mkmf.log file for more
details.  You may need configuration options.

    I fixed this, somehow. I removed all of the rvm packages (libxml2, iconv, libxslt, etc.) except for zlib using rvm pkg uninstall <package> I then re-installed 1.9.3 using rvm reinstall 1.9.3

    Then I did a gem install nokogiri and it worked just fine…

    I don’t completely understand why it works now, perhaps the libxml2, iconv, libxslt rvm packages are bad?
