ios – 使用资源包发布cocoapod

s.subspec 'Resources' do |resources|
    resources.resource_bundle = {'SparkSetup' => ['Resources/**/*']}
end

Resources文件夹包含格式Images.xcassets(普通XCode格式)的资产目录.我的项目包含两个目标 – 主lib目标和资源包目标,其中包含故事板和上述资产目录文件.我引用了主要的lib代码.没有问题.

当我尝试pod lib lint时,我得到：

cocoapod工具失败并崩溃/返回错误,因此我无法发布pod.它以前工作很好的几个cocoapods工具版本(不记得0.36或更早)

有任何建议如何解决这个问题？有资源包的cocoapods的最佳行动方案是什么？
