Question

我写了一个小型库，将被多个iOS应用程序使用。

我已经根据我的知识配置了规范，并想象它应该可以工作，但事实并非如此。

以下是规范：

Pod::Spec.new do |s|                                                                                                                                    
  s.name                  = 'TheLib'                                                                                                                  
  s.version               = '1.0.0'                                                                                                                     
  s.ios.deployment_target = '5.0'                                                                                                                       
  s.source_files          = 'Source/**/*.{h,m}'                                                                                                         
  s.resources             = 'Source/View/Storyboard/*.storyboard'                                                                                       
  s.dependency     'AFNetworking', '~> 1.3.3'                                                                                                           
  s.dependency     'SDWebImage', '~> 3.5'                                                                                                               
  s.dependency     'FrameAccessor', '~> 1.2.0'                                                                                                          
  s.dependency     'NSDate+TimeAgo', '~> 1.0.2'                                                                                                         
end

root只包含spec和Source dir，后者包含.h＆amp;的目录。 .M。

当我运行pod spec lint时，我得到：

[!] Oh no, an error occurred.

Search for existing github issues similar to yours:

但是，阅读GitHub页面上的3个帖子不会产生任何答案。这就好像没有添加源或其他东西（NilClass？）。

当我在使用该库的项目目录中运行pod install时，使用此podfile：

pod 'TheLib', :path => '../TheLib'

并打开工作区，Xcode正确安装了所有deps，但有一个名为“Development Pods”的目录，其中包含一个“TheLib”目录，它只有4个虚拟文件。

如下所示：

Dev Pods

Answer 1

默认情况下，

pod spec lint的工作方式是从远程源下载代码，而不是使用本地项目。

您发布的回溯显示异常是在方法install_source_of_pod中引发的，后者随后调用download_source - 这将尝试从远程源下载项目，这是因为失败，因为您尚未指定提供规范的source属性。

提供a valid source attribute应解决此特定错误。

本地CocoaPod规格失败
