带有Xcode 5和10.10优胜美地的Cocoapods

Question

After initially upgrading to 10.10 and XCode6-Beta, I tried to run 'pod update' and I received this error:

cannot load such file -- xcodeproj/prebuilt/universal.x86_64-darwin14-2.0.0/xcodeproj_ext (LoadError)

I tried to update Cocoapods using 'sudo gem install cocoapods', but received another error:

Fetching: xcodeproj-0.17.0.gem (100%)
Building native extensions.  This could take a while...
ERROR:  Error installing cocoapods:
ERROR: Failed to build gem native extension.

Could not create Makefile due to some reason, probably lack of necessary libraries and/or headers.  Check the mkmf.log file for more details.  You may need configuration options.

Even though I have installed XCode 6, I would like to use XCode 5 at this time because I want to make releases.

Answer 1

You'll need to reinstall the cocoapod gem and use XCode6's Command Line Tools, as specified by this answer. Then you can do a pod install and continue to use XCode5. Just open the xcworkspace created in XCode5 instead of XCode6Beta.

Answer 2

Simply deleting ~/.rvm folder resolves the problems that arise from ruby/library version, ACL, and configuration conflicts. All your gems will have to be reinstalled but this is the simplest and cleanest solution I know of that works with Xcode 5. Just run

> sudo rm -rf ~/.rvm

in s.hell.
