Unable to install gem on mountain lion?

Rails
1

Hello,
I’m trying to install a specific gem but getting this error message
below.

ERROR: Error installing nokogiri:

/Library/Ruby/Gems/1.8/gems/nokogiri-1.5.5/ext/nokogiri/gem_make.out

I’ve seen that some folks have resolved this issue by reinstalling the
new
version of x-code. Which I did - but no avail.
Any tips?

Thanks.

Hm… Interesting. I went and installed the extra extension into xcode.
but now getting a different output.

Gem::Installer::ExtensionBuildError: ERROR: Failed to build gem native

Ah…fixed with homebrew and these instructions here.

In new versions of XCode you need to specifically install the command
line
tools for this to work.

Check here for a screenshot of how to:
