Install Nokogiri gem on OS X

Question

Trying to install Nokogiri and I get the following error

checking for libexslt/exslt.h... yes

make: *** [html_document.o] Error 1

I think I need to use a brew install gcc rather the one I have, but I can't remember how! :)

I have:

gcc -v
Configured with: --prefix=/Applications/Xcode.app/Contents/Developer/usr --with-gxx-include-dir=/usr/include/c++/4.2.1
Apple LLVM version 5.0 (clang-500.2.79) (based on LLVM 3.3svn)
Target: x86_64-apple-darwin12.5.0
Thread model: posix

thanks!

Your GCC version looks fine to me. I'm on Mavericks (and it looks like you're on Lion?), so my version is slightly different (x86_64-apple-darwin13.0.0 instead of x86_64-apple-darwin12.5.0) but otherwise identical to what you posted.

I had problems with nokogiri until I had RVM set to use Ruby 1.9.3 as the default instead of 1.9.2. My nokogiri gem was pulled in when I updated Vagrant to 1.4.0, though, and was not installed on its own with a "gem install nokogiri". I just ran a "gem install nokogiri" and it rebuilt without errors for me.

I'd recommend doing the following:

brew update # just in case
rvm use ruby-1.9.3-p392
rvm alias create default ruby-1.9.3-p392
gem install nokogiri
