CocoaPods最新版本升级

转自：https://juejin.im/post/5ad0c92a518825364001db63

升级CocoaPods的步骤和安装的时候差不多，具体参考如下步骤:

1. 首先我们可以查看下当前的版本号命令如下:

pod --version 

1.2.0 // 本机安装的版本

2. 在升级之前我们需要了解当前安装的Ruby源地址：

gem source -l 

*** CURRENT SOURCES ***

http://rubygems.org/

https://gems.ruby-china.com/

https://ruby.taobao.org/

上面我已经添加过新的源

3. 移除淘宝的Ruby源，添加一个新的源（注意：目前淘宝的源已经不能用了）

// 移除旧的源: gem sources --remove https://ruby.taobao.org/  https://ruby.taobao.org/ removed from sources

// 添加新的源:gem sources -a https://gems.ruby-china.com

/// 因为已经添加过了sourcehttps://gems.ruby-china.com/ already presentinthe cache

4. 查看新的源是否添加成功，使用的命令和步骤2一样

gem source -l 

*** CURRENT SOURCES ***

https://gems.ruby-china.com/

5. 开始安装，输入如下命令：

sudo gem install cocoapods

然后会出现下面的东西

可能会报错:

Operation not permitted - /usr/bin/xcodeproj

解决办法：sudo gem install -n /usr/local/bin cocoapods 

While executing gem ... (TypeError) no implicit conversion of nil into String

// 解决办法是执行如下命令更新gemsudo gem update --system复制代码

6. 再次查看下CocoaPods的版本，已经成功升级咯！

pod --version1.5.0
