MAC OS 10.12.3 安装cocoapods 执行 pod setup 报错:

error: RPC failed; curl 56 SSLRead() return error -36
fatal: The remote end hung up unexpectedly
fatal: early EOF
fatal: index-pack failed

解决方案:
1:移除repo master

sudo rm -fr ~/.cocoapods/repos/master

2:将 https://github.com/CocoaPods/Specs.git ~ clone 到 ~/.cocoapods/repos/master 目录下

git clone https://github.com/CocoaPods/Specs.git  ~/.cocoapods/repos/master

3:重新执行 pod setup
