修复cocoapods

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 update
Update all pods
Analyzing 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>&1

Updating spec repo `master`
  $ /usr/bin/git pull --ff-only

[!] 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:

2.http://blog.cocoapods.org/Repairing-Our-Broken-Specs-Repository/

解决方法:删除本地缓存,重新setup

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