當(dāng)你拿到別人的代碼在自己的電腦上運行的時候，有時候會發(fā)現(xiàn)用CocoaPods導(dǎo)入的框架報錯了，例如AFNetworking框架。下面是一些可能出現(xiàn)的一些錯誤整合：

pod install 后出現(xiàn)的問題：
$ pod install 
Analyzing dependencies 
[!] Unable to satisfy the following requirements: 
-AFNetworking (~> 3.0) required by Podfile 
None of your spec sources contain a spec satisfying the dependency: AFNetworking (~> 3.0). 
You have either: 
* out-of-date source repos which you can update with pod repo update. 
* mistyped the name or version. 
* not added the source repo that hosts the Podspec to your Podfile. 
Note: as of CocoaPods 1.0, pod repo update does not happen on pod install by default.

解決辦法

$ pod repo remove master
$ pod repo add master https://gitcafe.com/akuandev/Specs.git
$ pod repo update

$ pod repo add master https://gitcafe.com/akuandev/Specs.git有可能出現(xiàn)錯誤，就用pod setup,如果用pod setup卡住，那么可以用如下的方式：
1，cd ~/.cocoapods //進到安裝cocoa pod 的repo目錄
2，open . //打開目錄此時里面應(yīng)該是空的啥也沒有
具體的操作方式

具體操作。 
cd ~/.cocoapods/repos 
git clone https://github.com/CocoaPods/Specs.git master
這個命令需要的時間是很長的，如果中間出現(xiàn)錯誤：
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 
解決辦法
$ sudo xcode-select -switch /Applications/Xcode.app/Contents/Developer
如果你安裝了多個xcode，命令需要修改一下
$ sudo xcode-select -switch /Applications/Xcode 7.3.1.app/Contents/Developer
在重新執(zhí)行g(shù)it clone https://github.com/CocoaPods/Specs.git master這個命令，完成以后，就可以pod install了
