问题描述：

我创建依赖于另一个私有荚私人荚棉短绒效果很好，当我不添加任何依赖关系，而当我添加的依赖和运行lint命令它给我的错误在专用窗格上执行lint命令时出错“验证期间遇到未知错误（无法将nil隐式转换为字符串）”。

Encountered an unknown error (no implicit conversion of nil into String) during validation.

的林特命令：

pod spec lint --private --sources=https://github.com/*****/****.git

这是我的podSpec它有什么问题，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" => "[email protected]****.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：

私有的依赖关系应该在哪里？私人回购？你有没有尝试添加“：git”或类似的东西？因为如果它是私人的未知的，它仍然需要获取它。也许看看那里：https://stackoverflow.com/questions/16905112/cocoapods-dependency-in-pod-spec-not-working – Larme

答

尝试通过运行rm -rf ~/.cocoapods，然后运行pod setup清除当地的CocoaPods缓存。

您的podspec似乎是有效的，如果这不能帮助您应该尝试取消注释您的s.dependency并再次linting它，因为依赖性pod也可能是导致此崩溃的那个。

是的，它是这样做的，但依赖关系窗格是有效的，我们在不同的项目中使用它。我做了你所说的，仍然是同样的错误 – nmortada
