 wangwang:WWTestCocoaPodsError wangyongwangyongwang$

执行pod init的时候的错误提示

　　解决问题：根据错误提示可以发现参考 使用CocoaPods出现问题的时候都可以查看CocoaPods issues 我这边的错误是参考的 pod init error #7208

　　解决方法：关键的命令是这一句：Try gem install cocoapods -v 1.4.0.beta.2 or gem install cocoapods -v 1.3.1

然后就没问题了

　　插曲：其实我在解决上边问题的时候，第一次忘了输入cocoapods了，然后报错如下

ERROR:  While executing gem ... (Gem::CommandLineError)

Please specify at least one gem name (e.g. gem build GEMNAME)

　　解决办法：后来我正确输入命令没问题后，就解决了这个问题了

　　自我分析：上边的命令是让我们更新Cocoapods到1.3.1版本，我在更新前都是用的比较老的1.0.1 (pod --version查看安装的Cocoapods的版本)

　　多想一点CocoaPods的本质到底是什么：

深入理解 CocoaPods 提到CocoaPods 是开发 OS X 和 iOS 应用程序的一个第三方库的依赖管理工具。CocoaPods是用 Ruby 写的，并由若干个 Ruby 包 (gems) 构成的。所以她才会用gem intall 这种方式安装Cocoapods

CocoaPods是这么说自己的：CocoaPods is a dependency manager for Swift and Objective-C Cocoa projects. It has over 39 thousand libraries and is used in over 2.7 million apps. CocoaPods can help you scale your projects elegantly.CocoaPods is built with Ruby and is installable with the default Ruby available on OS X. We recommend you use the default ruby.

CocoaPods是对于Swift和Objective-C的Cocoa项目的依赖管理工具，她已有39000多个库，并且应用于27万多个app。CocoaPods可以帮助你使你的项目更小更优雅。CocoaPods的基础是Ruby，并且OS X上默认已经安装了Ruby，我们建议您使用默认的Ruby。

关于gem更多内容  gem的简单命令

　　2.在使用pod update --verbose --no-repo-update的时候不能够正常地导入所要导入的第三方库

　　我要导入的库是 pod 'CYLTabBarController', '~> 1.14.1'

　　提示的问题是：

 [!] Unable to satisfy the following requirements:

 - `CYLTabBarController (~> 1.14.)` required by `Podfile`

 None of your spec sources contain a spec satisfying the dependency: `CYLTabBarController (~> 1.14.)`.

 You have either:

  * out-of-date source repos which you can update with `pod repo update` or with `pod install --repo-update`.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

　　检查了本地的版本：pod --version

 wangwang:WWCopyHomeWorkBox wangyongwangyongwang$ pod --version

 1.3.

　　检查pod 库中是否存在我们要添加的相应的版本的pod库：当我执行pod Search CYLTabBarController的时候显示如下：显示表明 pod 库里边有我要添加的这个版本

 wangwang:WWCopyHomeWorkBox wangyongwangyongwang$ pod search CYLTabBarController

 -> CYLTabBarController (1.14.)

 (END)

　　最后是直接执行的pod update

然后就下载pod 库（CYLTabBarController）成功了

 wangwang:WWCopyHomeWorkBox wangyongwangyongwang$ pod update
