这一行是我的 podfile 导致了这个问题:
pod 'JiveCommon', :path => 'Common/JiveCommon'
在我的根目录下有一个文件名“Common”，在项目名称 JiveCommon 中，女巫本身就是一个 pod。
我曾经在子模块中这样使用它，所以我可以从当前项目上下文中更改和编辑文件，但是在升级到 Cocoapods v 1.0 后，我收到了这个错误:
### Error

如果有使用“路径”语法的不同最佳实践，我查看了纪录片，但没有找到任何东西..
同样的问题出现在 Githb 问题上:https://github.com/CocoaPods/CocoaPods/issues/4814
但没有解决方案解决它。
还有其他人有同样的经历吗？
最佳答案
我已经设法解决了这个问题，如果其他人会面临同样的问题，在子模块 pod 规范中，我需要更改:
更改 source_files 没有帮助。我有一个私有(private) podspec，以前包含
s.source_files = 'Common/**/*
To
s.source_files = 'Common/**/*.{m,h,mm,hpp,cpp,c}'
关于ios - NoMethodError - 未定义的方法 `path' for nil :NilClass Cocoapods version 1. 0，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/37521959/
