CocoaPods 正确打开姿势

1、首先查看当前pod 的版本：

pod --version    

截止当前2019年2月26号最新版本号：1.6.1

2、了解当前Ruby的源地址

gem source -l

*** CURRENT SOURCES ***                                                                 http://rubygems.org/                                                                                 https://gems.ruby-china.org/                                                           https://ruby.taobao.org/

3、以前都是淘宝源，现在都不能用了，删除统一改为https://gems.ruby-china.com/

// 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/ 

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.org/

5. 开始安装，输入如下命令：

sudo gem install cocoapods

Password:

13 gems installed

报错:

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

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

6. 再次查看下CocoaPods的版本，已经成功升级咯！

pod --version

1.6.1

7、pod search 总是报异常错误

[!] Unable to find a pod with name, author, summary, or descriptionmatching '······'

7.1.执行pod setup

其实在你安装CocoaPods执行pod install时，系统会默认操作pod setup，然而由于中国强大的墙可能会pod setup不成功。这时就需要手动执行pod setup指令，如下：

终端输入：pod setup

会出现Setting up CocoaPods master repo，稍等几十秒，最底下会输出Setup completed。说明执行pod setup成功。

如果pod search操作还是搜索失败，如下：

终端输入：pod search AFNetworking

输出：Unable to find a pod with name, author, summary, or descriptionmatching 'AFNetworking' 这时就需要继续下面的步骤了。

7.2.删除~/Library/Caches/CocoaPods目录下的search_index.json文件

pod setup成功后，依然不能pod search，是因为之前你执行pod search生成了search_index.json，此时需要删掉。

终端输入：rm ~/Library/Caches/CocoaPods/search_index.json

删除成功后，再执行pod search。

7.3.执行pod search

终端输入：pod search afnetworking(不区分大小写)

输出：Creating search index for spec repo 'master'.. Done!，稍等片刻······就会出现所有带有afnetworking字段的类库。
