我试图让Travis版本通过open source project，但没有运气：
示例项目的Podfile如下所示：
abstract_target 'Common' do
#Swift 3 Pods
pod 'BNRDeferred', :git => 'https://github.com/bignerdranch/Deferred.git', :branch => 'swift-3_0'
pod 'BSWFoundation', :path => '../BSWFoundation.podspec'
target 'BSWFoundationPlayground'
target 'Tests'
端
但build is failing出现此错误：
Pre-downloading: `BNRDeferred` from `https://github.com/bignerdranch/Deferred.git`, commit `4fad78faf79c6f386f780bffb7c78ecdfbd1f10b`
[!] Unable to find a specification for 'BNRDeferred'.
知道可能会发生什么吗？我在Travis上使用Xcode 8 osx_image，项目pod install在本地工作正常
