iOS 升级cocoaPods

在利用pod导入Alamofire时,执行pod install或pod update遇到了这样一个错误:

[!] Unable to satisfy the following requirements:

  • Alamofire (~> 4.4) required by Podfile

None of your spec sources contain a spec satisfying the dependency: Alamofire (~> 4.4).

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* out-of-date source repos which you can update with pod repo update.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.

提示的意思就是:源库里面不包含Alamofire (~> 4.4),需要更新cocoaPods镜像库。所有升级一下cocoaPods就可以解决问题,按下面升级步骤升级完后,再执行pod install或pod update,就正常了。升级步骤如下:

一:查看ruby源
指令:

$ gem sources -l

返回信息:

https://ruby.taobao.org

二:删除之前的源
指令:

$ gem sources --remove https://ruby.taobao.org

返回信息:

`https://ruby.taobao.org removed from sources`

三、添加最新的源。ruby-china
指令:

$ gem sources -a https://gems.ruby-china.org

返回信息:

https://gems.ruby-china.org added to sources

四、检查源是否添加成功
指令:

$ gem sources -l

返回信息:

https://gems.ruby-china.org

五、安装cocoapods
指令:

$ sudo gem install -n /usr/local/bin cocoapods

返回信息:

Password:输入电脑密码
Fetching: nanaimo-0.2.3.gem (100%)
.........(略)
15 gems installed

六、查看pod版本
指令:

$ pod --version

返回信息:

1.2.1

七、更新Podspec索引文件,创建本地索引库
注:这里要等一段时间,耐心等待
指令:

$ pod setup

返回信息:

Setting up CocoaPods master repo
  $ /usr/bin/git -C /Users/yunlong/.cocoapods/repos/master fetch origin
  --progress
  remote: Counting objects: 533597, done.        
  remote: Compressing objects: 100% (8680/8680), done.        
...........(略)
Setup completed
