在拉下松爷更新的Podfile后，尝试用pod update更新，结果出现下面错误

$pod updateUpdate all podsAnalyzing dependencies[!] Unable to satisfy the following requirements:- `JSQMessagesViewController (~> 6.1.0)` required by `Podfile`

没什么头绪，尝试查一下版本

$pod list | grep JSQM  JSQMessagesViewController 6.0.0

JSQMessagesViewController主页明明标了已经是6.1.1，是不是版本库有本地缓存，在pod --help加google下，发现命令pod repo update，果断运行一下，卡住，加上–verbose

$pod repo update --verbose  $ /usr/bin/git rev-parse  >/dev/null 2>&1Updating spec repo `master`  $ /usr/bin/git pull --ff-only  error: Your local changes to the following files would be overwritten by merge:  CocoaPods-version.yml  Specs/AdMobMediationAdapterMMedia/1.5.0/AdMobMediationAdapterMMedia.podspec.json  Please, commit your changes or stash them before you can merge.  error: The following untracked working tree files would be overwritten by merge:  Specs/AAShareBubbles/1.1.0/AAShareBubbles.podspec.json  ...[略去n行]  Specs/AQSEvent/0.2.0/AQSE  Aborting  Updating da90008..86016e3[!] CocoaPods was not able to update the `master` repo. If this is an unexpected issue and persists you can inspect it running `pod repo update --verbose`

果然本地有缓存，还是git管理的，更新时冲突，google了一下，找到相关资料：

解决方法：删除本地缓存，重新setup

$rm -fr ~/.cocoapods/repos/master$pod setup
