Yeah, the github web UI can't 'handle our scale', but that doesn't effect the actual git repo.
I can't reproduce this using CocoaPods 0.38.2. Can you try and boil this down to a Podfile that reproduces the issue in a clean project
@orta thats not correct -- 2.4.x matches
Ah, fair, deleting my post - not gonna leave bad info out there.
I installed cocoapods-1.0.0.beta.2 and has returned the same error... i send you a project new and the verbose log...
That project installs fine for me. Can you rm -rf ~/.cocoapods/repos/master and try installing again?
Thank You! Now... It works!
