OS X [REDACTED] Ruby 2.0 headers fix.
sdk_rb_usr=`xcode-select -p`/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.9.sdk/System/Library/Frameworks/Ruby.framework/Versions/2.0/usr
sudo cp -r $sdk_rb_usr/include $sys_rb_usr/include

This worked for me, thanks so much!


I had to change to -print-path:

sdk_rb_usr=xcode-select -print-path/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.9.sdk/System/Library/Frameworks/Ruby.framework/Versions/2.0/usr
sudo cp -r $sdk_rb_usr/include $sys_rb_usr/include


Loves it! Smooches 9000! Fix for ill-befitting Ruby shenanigans with Cocoapods on 10.9 Mavericks.


Worked for me too! Thanks!!!!!


I've got RVM, do you think this will still work for me?


Outstanding! Thanks a million.


Since I've updated to Command Line Tools 5.0.0 with Mavericks DP2, I remove Platforms/MacOSX.platform/Developer/ because I've no such thing here.

sdk_rb_usr=`xcode-select -p`/SDKs/MacOSX10.9.sdk/System/Library/Frameworks/Ruby.framework/Versions/2.0/usr
sudo cp -r $sdk_rb_usr/include $sys_rb_usr/include

Excellent, thank you!

One note for others, this script fails when you have Xcode 4.6.x set as your default for command-line builds. Run the command below beforehand, adapting for the latest developer preview version you have installed as appropriate:

xcode-select --switch /Applications/

Phatblat - your entry was just what I needed..after being stuck for more than a day - Thanks much!


Is this working for people using Rbenv?


Xcode5 GM doesn't ship with 10.9 SDK, any ideas?


@zhigang1992, Yeah, download Xcode 5 DP 6 from the Mavericks dev center and use the SDK out of that bundle.


@owensd, for those of us who don't use the Terminal much (like me) how would we go about doing that? I'm currently running DP 8 of [Redacted] and have Xcode 5 from the App Store and having issues getting cocoa pods to install...


@danmartyn simply download the Xcode 5 preview from the Mavericks dev centre, once its downloaded, open the disk image, and right click on the Xcode icon and choose "show package contents", from there navigate to Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/and copy the 10.9 sdk - then do the same with your app store downloaded Xcode and paste the 10.9 sdk into the MacOSX.platforms' SDKs folder. Done.


Anyway to run this without having the Xcode 5 DP?


There is Xcode 5.0.1 GM (with 10.9 sdk) seed in iOS Dev Center now.


Had to reinstall ruby (with rbenv) to get things working again (installed the xcode GM before that)


Seems like Xcode 5.0.1 GM fixes this problem.


XCode 5.0.1 release definitely is fixing this issue.


Thanks, the workaround worked :-). Even with 5.0.1 installed from the App Store it didn't work.


I can confirm that upgrading to Xcode 5.0.2 solved my problem as well.


Sorry for a little off topic, does anyone meet the following issue with Yosemite and Xcode 6 beta

/Library/Ruby/Site/2.0.0/rubygems/ext/builder.rb:159:in `synchronize': ERROR: Failed to build gem native extension. (Gem::Ext::BuildError)

    ERROR: Failed to build gem native extension.

    deadlock; recursive locking

It seems Apple makes another bug with Ruby in Yosemite
