无法解析 Pod 安装/更新时的 Podfile.lock 错误

Question

无法更新/安装 pod。
错误是“无法解析 Podfile.lock 文件”。
最后安装的 pod 是：pod 'googleapis', :path => '.'
之后问题开始出现。

COCOAPODS: 1.4.0.beta.2

如何解决错误。即使我必须删除 googleapis pod，我也会这样做。但是从 podfile 中删除它并点击 pod-install 命令不起作用，因为 pod-intsall/pod-update 命令总是会产生这个错误。

这是一个 CocoaPods issue 已在 1.4.0 中修复。

解决方法是在pod install 或pod update 之前删除Podfile.lock。
