我正在遵循Xcode存储库的一些说明。
$ bundle exec pod install
Analyzing dependencies
[!] The version of CocoaPods used to generate the lockfile (1.9.3) is higher than the version of the
current executable (1.6.1). Incompatibility issues may arise.
我认为这导致了错误：
Failed to find known source with the URL "trunk"
当我检查pods的版本时，我得到：
$ pod --version
1.10.0
我的假设(但我可能错了(是，我要么需要运行命令，让它运行pod的新版本，要么我需要在不同的地方安装新版本。

我已经多次遇到这个问题，但不知道为什么。要修复此问题，我在项目目录中运行以下终端命令：
sudo gem install cocoapods-deintegrate cocoapods-clean(仅当您没有安装cocoapods-deintegrate和cocoapods-clean时(
pod deintegrate
pod clean
pod setup
pod install
据我所知，这将完全清除并重新安装pod文件。再次，我不确定是什么原因导致问题开始，但这对我有效。
