如果出现以下错误：

ERROR: Could not find a valid gem ‘cocoapads’ (>= 0) in any repository

ERROR: Possible alternatives: cocoapods, cocoaseeds, socmap_adf

ERROR: While executing gem … (Gem::FilePermissionError)

You don’t have write permissions for the /usr/bin directory.

你就干这个命令：

sudo gem install cocoapods -n /usr/local/bin

结果往下走又出问题了：

欢迎大家来到IT世界,在知识的湖畔探索吧!cuixideiMac:~ cuixi$ pod setup Setting up CocoaPods master repo fatal: ambiguous argument 'HEAD': unknown revision or path not in the working tree.

If this is an unexpected issue and persists you can inspect it running `pod repo update --verbose` 

错误2

网上查的要输入卸载命令，结果又出问题了

图例3

最后没办法：~/.cocoapods/ 前往这个文件夹，手动删除；

正常下载中

成功了，想更新最新的1.6.0 beta2的执行它提示的命令即可

问题终于解决了！
