Cocoapods: LoadError - no such file to load

Question

I am trying to add a pod to my Xcode project. I am getting this error:

LoadError - no such file to load -- xcodeproj/prebuilt/universal-darwin13.0-1.8.7/xcodeproj_ext /Library/Ruby/Site/1.8/rubygems/core_ext/kernel_require.rb:55:in gem_original_require' /Library/Ruby/Site/1.8/rubygems/core_ext/kernel_require.rb:55:in require' /Library/Ruby/Gems/1.8/gems/xcodeproj-0.14.0/lib/xcodeproj/ext.rb:6 /Library/Ruby/Site/1.8/rubygems/core_ext/kernel_require.rb:55:in gem_original_require' /Library/Ruby/Site/1.8/rubygems/core_ext/kernel_require.rb:55:in require' /Library/Ruby/Gems/1.8/gems/xcodeproj-0.14.0/lib/xcodeproj/project.rb:4 /Library/Ruby/Gems/1.8/gems/cocoapods-0.27.1/lib/cocoapods/installer/analyzer.rb:488:in compute_target_platforms' /Library/Ruby/Gems/1.8/gems/cocoapods-0.27.1/lib/cocoapods/installer/analyzer.rb:485:in each' /Library/Ruby/Gems/1.8/gems/cocoapods-0.27.1/lib/cocoapods/installer/analyzer.rb:485:in compute_target_platforms' /Library/Ruby/Gems/1.8/gems/cocoapods-0.27.1/lib/cocoapods/installer/analyzer.rb:55:in analyze' /Library/Ruby/Gems/1.8/gems/cocoapods-0.27.1/lib/cocoapods/installer.rb:171:in analyze' /Library/Ruby/Gems/1.8/gems/cocoapods-0.27.1/lib/cocoapods/installer.rb:94:in resolve_dependencies' /Library/Ruby/Gems/1.8/gems/cocoapods-0.27.1/lib/cocoapods/user_interface.rb:52:in section' /Library/Ruby/Gems/1.8/gems/cocoapods-0.27.1/lib/cocoapods/installer.rb:93:in resolve_dependencies' /Library/Ruby/Gems/1.8/gems/cocoapods-0.27.1/lib/cocoapods/installer.rb:86:in install!' /Library/Ruby/Gems/1.8/gems/cocoapods-0.27.1/lib/cocoapods/command/project.rb:38:in run_install_with_update' /Library/Ruby/Gems/1.8/gems/cocoapods-0.27.1/lib/cocoapods/command/project.rb:68:in run' /Library/Ruby/Gems/1.8/gems/claide-0.3.2/lib/claide/command.rb:206:in run' /Library/Ruby/Gems/1.8/gems/cocoapods-0.27.1/lib/cocoapods/command.rb:51:in run' /Library/Ruby/Gems/1.8/gems/cocoapods-0.27.1/bin/pod:19 /usr/bin/pod:23:in load' /usr/bin/pod:23

My podfile contents:

pod 'RestKit', '~> 0.21.0'

Any help would be appreciated!

Answer 1

I also was seeing this. Running this fixed the issue:

sudo gem install cocoapods && pod install

Answer 2

Finally found a solution: I'm running old Xcode4 and new Xcode5 in same machine with same projects. At some point I seem to have lost command line tools (and iPhone5 simulator).

Reinstalling command line tools solved the problem for me. Since Xcode 4.6.3 menu item Xcode - Preferences - Downloads - Components didn't have command-line tools any more for unknown reasons, here is another way to install them:

xcode-select --install

--install
          Opens a user interface dialog to request automatic installation of the
          command line developer tools.

Now running "pod install" worked just fine.

if you are using 10.10 and are seeing this error (/System/Library/Frameworks/Ruby.framework/Versions/2.0/usr/lib/ruby/2.0.0/rubygems/core_ext/kernel_require.rb:55:) try this

Open Xcode 6 > Preferences > Locations
Command Line Tools version to Xcode 6.0
Uninstall cocoapods/xcodeproj then re-install.

sudo gem uninstall cocoapods
sudo gem uninstall xcodeproj
sudo gem install xcodeproj
sudo gem install cocoapods

pod --version
