1、卡在
Cloning spec repo `cocoapods` from `git@github.com:CocoaPods/Specs.git`
解决方法：
pod setup
cd ~/.cocoapods/repos
git clone --depth 1 https://github.com/CocoaPods/Specs.git master
2、如果报错：
error: RPC failed; curl 18 transfer closed with outstanding read data remaining
fatal: The remote end hung up unexpectedly
fatal: early EOF
fatal: index-pack failed
解决方法：
git config --global http.postBuffer 524288000
3、Git设置克隆深度后看不到远端分支
执行git-clone - depth xxxxx.git深度拷贝后，看不到远端分支
解决方法：
git remote set-branches origin '*' //追踪所有分支
再拉取一下就可以看到了
