I\'ve just updated to OS X Mountain Lion and I\'m getting the following when working with rails and terminal.
WARNING: Nokogiri was built against LibXML vers
I just had this problem.
My problem was solved surprisingly easily.
gem uninstall nokogiri
Selected all versions
Then gem install nokogiri
and it went away.
if you are using home-brew, you can brew update
and brew doctor
. Upgrading to mountain lion even removed my git and stuff. I installed it back by installing cc tools in Xcode and using brew doctor to make sure it's raring to go
before the above.
