系統更新，我在安裝cocoapodsfa遇到了下面一些問題，幾番折騰才成功安裝。這里和大家分享一下：
問題：路徑錯誤
?? ~? 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
我的系統是：macOS Sierra 10.12.1
開發工具：Xcode8
解決辦法：
?? ~? pod repo list
0 repos
這表示cocoapods并沒有被成功安裝，刪除master分支 重新建立新的分支
?? ~? sudo -rm -rf ~/.cocoapods/
usage: sudo -h | -K | -k | -Vusage: sudo -v [-AknS] [-g group] [-h host] [-p prompt] [-u user]usage: sudo -l [-AknS] [-g group] [-h host] [-p prompt] [-U user] [-u user] [command]usage: sudo [-AbEHknPS] [-C num] [-g group] [-h host] [-p prompt] [-u user] [VAR=value] [-i|-s] []usage: sudo -e [-AknS] [-C num] [-g group] [-h host] [-p prompt] [-u user] file ...
?? ~? sudo xcode-select --switch /Applications/Xcode-beta.app
/Applications/Xcode-beta.app這個路徑請不要復制粘貼，而是打開finder，應用程序，將Xcode拖到終端生成路徑
檢驗路徑：
?? ~? xcode-select --print-path
/Applications/Xcode-beta.app/Contents/Developer
再次更新
?? ~? pod setup
Setting up CocoaPods master repo
CocoaPods 1.2.0.beta.1 is available.
To update use: `sudo gem install cocoapods --pre`
[!] This is a test version we'd love you to try.
For more information, see https://blog.cocoapods.org and the CHANGELOG for this version at https://github.com/CocoaPods/CocoaPods/releases/tag/1.2.0.beta.1
Setup completed
測試一下CocoaPods是否能用
?? ~? pod search afnetworking
-> AFNetworking+AutoRetry (0.0.5)
Auto Retries for AFNetworking requests
pod 'AFNetworking+AutoRetry', '~> 0.0.5'
- Homepage: https://github.com/shaioz/AFNetworking-AutoRetry
- Source:? https://github.com/shaioz/AFNetworking-AutoRetry.git
- Versions: 0.0.5, 0.0.4, 0.0.3, 0.0.2, 0.0.1 [master repo]
這樣就OK了,安裝完畢。
