CocoaPods-安装、更新、报错等使用总结

CocoaPods简介:

CocoaPods是一个用Ruby写的、负责管理iOS项目中第三方开源库的工具，CocoaPods能让我们集中的、统一管理第三方开源库，为我们节省设置和更新第三方开源库的时间。

CocoaPods安装:

因为Mac电脑自带Ruby环境，我们就只需打开终端开始动手。然而又因为默认情况下我们mac系统自带的Ruby环境版本比较低（大概是2.0.0或者其他较高版本），但是现在安装CocoaPods需要2.2.2版本及以上的，所以我们不管三七二十一先直接先升级ruby。

更新Ruby

安装CocoaPods：sudo gem install -n /usr/local/bin cocoapods：可能需要输入电脑密码：

执行结果：

如果安装了多个Xcode使用下面的命令选择（一般需要选择最近的Xcode版本）：sudo xcode-select -switch /Applications/Xcode.app/Contents/Developer；
安装本地库：pod setup：

执行结果：
```
Setting up CocoaPods master repo
  $ /usr/bin/git clone https://github.com/CocoaPods/Specs.git master --progress
  Cloning into 'master'...
  remote: Counting objects: 1879515, done.        
  remote: Compressing objects: 100% (321/321), done.        
  Receiving objects:  21% (404525/1879515), 73.70 MiB | 22.00 KiB/
```
然后就是漫长的等待，当然,网络好的情况下会更快。

说明：该步骤是安装本地库，不安装也没事，项目可以照常pod install。

只不过不安装的话就不能使用pod search 命令了；如果你追求完美那就继续往下看；

最新版的MacOS Catalina 及以后的系统命令行执行pod setup命令后直接结束啦；

需要手动安装本地库：
```
git clone https://github.com/CocoaPods/Specs.git ~/.cocoapods/repos/trunk
```
目录结构见下图,如果不是就自己手动移动一下：

CocoaPods版本升级

执行命令：gem -v，查看当前RubyGems版本；
执行命令：gem sources -l，查看RubyGems源，确保只有 gems.ruby-china.com；

执行结果：
```
*** CURRENT SOURCES ***

https://gems.ruby-china.com
```
执行命令：gem sources --add https://gems.ruby-china.com/ --remove https://rubygems.org/，修改RubyGems源：删除rubygems.org源，添加gems.ruby-china.com源；
执行命令：gem update --system，如果需要管理员权限就执行：sudo gem update --system，更新RubyGems版本，可能需要FQ；
执行命令：pod --version，查看自己的CocoaPods版本号；

执行结果：1.8.4；
执行命令：sudo gem install cocoapods，安装或者更新CocoaPods；

输入电脑登录密码；

执行结果：

.....
.....
Installing ri documentation for cocoapods-1.9.1
Done installing documentation for ffi, ethon, typhoeus, cocoapods-core, xcodeproj, cocoapods after 33 seconds
6 gems installed

执行命令：pod --version，查看下CocoaPods版本号是否更新；

到此，CocoaPods升级完成了。

CocoaPods常用语法

// 安装最新版cocoapods
sudo gem install cocoapods --pre

// 移除本地master
sudo rm -fr ~/.cocoapods/repos/master

// 移除本地缓存
sudo rm -fr ~/Library/Caches/CocoaPods/

// 重新setup，如果很慢可使用问题1的解决方法（git clone）
pod setup --verbose

// 移除trunk
pod repo remove trunk

// 搜索
pod search AFNetworking

// 创建Podfile文件：
pod init

// 打开Podfile文件：
open Podfile

// 添加第三方Pod库：
pod 'Alamofire'

// 开始下载添加的所有的第三方Pod：
pod install

解决办法：终端运行：pod repo remove trunk；
