14,338 PointsInstalling Compass Error
When i try to install compass i get an error saying:
Building native extensions. This could take a while... ERROR: Error installing compass: ERROR: Failed to build gem native extension.
/System/Library/Frameworks/Ruby.framework/Versions/2.0/usr/bin/ruby -r ./siteconf20140820-5382-tt21mm.rb extconf.rb
mkmf.rb can't find header files for ruby at /System/Library/Frameworks/Ruby.framework/Versions/2.0/usr/lib/ruby/include/ruby.h
extconf failed, exit code 1
Gem files will remain installed in /Library/Ruby/Gems/2.0.0/gems/ffi-1.9.3 for inspection. Results logged to /Library/Ruby/Gems/2.0.0/extensions/universal-darwin-13/2.0.0/ffi-1.9.3/gem_make.out
Im completely new to the terminal and command line so I'm completely lost.

14,338 Pointshey guys thanks for the replies that didn't work either Sigouy Me, Fortunately i found online i needed to install Xcode.
For anyone else having this issue type $ xcode-select --install
You will then get a pop up to install Xcode. After, when you install compass it should work!!

2,215 PointsApple updated the Xcode command line tools, which upgraded clang to Apple LLVM version 5.1 (clang-503.0.38) (based on LLVM 3.4svn) and enabled a feature in clang that causes unknown compiler flags to hard error rather than warn.
For now you can work around the issue using:
export ARCHFLAGS="-Wno-error=unused-command-line-argument-hard-error-in-future"
and then try again
sudo gem install compass
Hope it helps.

38 PointsI had the same problem, after installing the Xcode development tools I was still having the error while trying to install compass, I tried the below, according to this post
sudo ln -s /usr/bin/llvm-gcc /usr/bin/gcc-4.2
If that doesn't work out, try agreeing with the Xcode licenses
sudo gcc

13,674 PointsHi Martin, I am getting the same error - but the Xcode isn't working. I don't want to mess around with my command line too much - but Im using a 2013 iMac. Installing Xcode is all you needed to do?

Courses Plus Student 1,008 PointsHaving the same issue and this fixed it for me. Thank you for this!
In addition: If this doesn't help you and you have Xcode downloaded from the App Store and haven't actually opened it yet, then this may be what you need to do in order to get this working. Xcode needs to finish installing after you accept the user agreement in order for all this to come together.
