上端时间删除了一些东西 感觉太占内存了 如图

安装吧 - 直接看报错后 因为前面是学习的时候 老版本了 镜像都有问题

• 查看现有镜像

gem source -l

• 先删除之前的 不可用的

gem sources --remove https://ruby.taobao.org/
gem sources --remove https://gems.ruby-china.org/

• 加入淘宝镜像

gem sources -a https://gems.ruby-china.com/

• 安装更新cocoapods
  参考CocoaPods最新安装和问题解决教程（干货）我就参考这个安装问题尤其是安装命令

你要输入密码 ，等待一段时间，根据网速决定

OS X 10.11以前，在终端输入以下命令：

sudo gem install cocoapods

OS X 10.11以后，在终端输入以下命令：

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

pod命令行

• pod init
  先打开工程 然后cd命令进入工程 创建Podfile文件 先用文本打开 然后pod你想pod的第三方库

pod 'Masonry'

• pod update / pod install
  速度很快的

• 小插曲 安装后的cocopods到底占多大内存 这边截图几张留作以后参考

报错

• [!] CDN: trunk Repo update failed

[!] CDN: trunk Repo update failed - 72 error(s):

很多内容不复制了.....

参考[!] CDN: trunk Repo update failed、[!] CDN: trunk Repo update failed - 39 error(s):、CDN: trunk URL couldn't be downloaded
解决方案亲自尝试的：
1）sudo gem install -n /usr/local/bin cocoapods

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

2. 在podfile文件添加内容

   
   image.png

source 'https://github.com/CocoaPods/Specs.git'

• 如果直接pod update 出现 [!] Failed to connect to GitHub to update the CocoaPods/Specs specs repo - Please check if you are offline, or that GitHub is down
  命令控制 pod install 先安装 后更新pod update

• [!] /user/bin/git https://github.com/Cocoapods/Specs.git -- mater
  Cloning int 'master'
  error: RPC failed; curl 56 LibreSSL SSL_read: SSL_ERROR_SYSCALL

其实吧 还是开梯子直接解决所有问题

升级cocopods

sudo gem install cocoapods
