裝了五次CocoaPods，終于裝上了，強烈感謝這篇帖子：

- 貼一下重點
安裝過程遇到的問題：
1、Ruby版本過低（更新就行了）
2、
$ pod setup
Setting up CocoaPods master repo
[!] /usr/bin/git clone https://github.com/CocoaPods/Specs.git master
Cloning into ‘master’…
error: RPC failed; curl 56 SSLRead() return error -36
fatal: The remote end hung up unexpectedly
fatal: early EOF
fatal: index-pack failed
3、
$ pod setup
Setting up CocoaPods master repo
[!] /usr/bin/git clone https://github.com/CocoaPods/Specs.git master
Cloning into ‘master’…
error: RPC failed; curl 56 SSLRead() return error -9806
fatal: The remote end hung up unexpectedly
fatal: early EOF
fatal: index-pack failed
4、
$ pod setup
Setting up CocoaPods master repo
[!] /usr/bin/git clone https://github.com/CocoaPods/Specs.git master
Cloning into ‘master’…
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
上面錯誤主要是os10.11+和cocoapods1.0+版本升級的安全機制更改造成的。主要出現在pod setup過程中，且該過程等待時間非常長。
解決方法：
- 鏡像用這個
$ gem sources --add https://gems.ruby-china.org/
- 安裝
$ sudo gem install -n /usr/local/bin cocoa pods
$ Git clone https://git.coding.net/CocoaPods/Specs.git ~/.cocoapods/repos/master
該過程作用與 pod setup作用相同，作者親測。效果極佳！！！！
另外我還翻墻了。
