我正在创建一个私有pod取决于另一个私有pod，当我不添加任何依赖时，linter工作得很好但是当我添加依赖项并运行lint命令时它会给我错误
Encountered an unknown error (no implicit conversion of nil into String) during validation.
lint命令：
pod spec lint --private --sources=https://github.com/*****/****.git
这是我的podSpec有什么问题，我应该怎么做才能解决这个问题？
Pod::Spec.new do |s|
s.name = "****Framework"
s.version = "1.0.0"
s.summary = "Summary ................."
s.homepage = "https://github.com/****/****Framework"
s.description = "Description ................."
s.license = "Simplified BSD license"
s.author = { "Nahla Mortada" => "nahla.mortada@****.com" }
s.platform = :ios, "9.0"
s.ios.deployment_target = "9.0"
s.source = { :git => "https://github.com/****/****Framework.git", :tag => s.version }
s.source_files = "****Framework/*.swift"
s.pod_target_xcconfig = {
'SWIFT_VERSION' => '3.0',
}
s.requires_arc = true
s.dependency '****'
end
完全错误：

尝试清除本地CocoaPods缓存，方法是运行rm -rf ~/.cocoapods，然后运行pod setup。
您的podspec似乎有效，如果这不起作用，您应该尝试取消注释s.dependency并再次使用它，因为依赖项pod也可能是造成此崩溃的
