最近需要重装一次。
检查是否有安装残留（删除CocoaPods）
如果之前装过cocopods，最好先卸载掉，卸载命令：
sudo gem uninstall cocoapods
先查看本地安装过的cocopods相关东西，命令如下：
gem list --local | grep cocoapods
会显示如下：
cocoapods-core (0.39.0)
cocoapods-downloader (0.9.3)
cocoapods-plugins (0.4.2)
cocoapods-search (0.1.0)
cocoapods-stats (0.6.2)
cocoapods-trunk (0.6.4)
cocoapods-try (0.5.1)
然后逐个删除吧：
//示例sudo gem uninstall cocoapods-core
二、使用Homebrew安装CocoaPods（无需翻墙）
1.安装安装 Homebrew
特别提示官方的无法连接安装，可以使用下面的进行使用
/bin/zsh -c "$(curl -fsSL https://gitee.com/cunkai/HomebrewCN/raw/master/Homebrew.sh)"
出现Installation successful!提示安装成功！
2.接着安装ruby，继续在终端中进行
brew install ruby
3.安装完成后替换一下ruby源
查看ruby源gem sources -l
CURRENT SOURCEShttps://rubygems.org/
替换ruby源
gem sources --add https://gems.ruby-china.com/ --remove https://rubygems.org/
4.查看是否替换成功
gem sources -l
如果出现的是https://gems.ruby-china.com/证明替换成功。
5.安装CocoaPods
执行下面一句
sudo gem install -n /usr/local/bin cocoapods

一、使用Homebrew安装CocoaPods（无需翻墙）
1.更改终端的配置,找到终端简介，勾选Rosetta
2.安装安装 Homebrew
/bin/zsh -c "$(curl -fsSL https://gitee.com/cunkai/HomebrewCN/raw/master/Homebrew.sh)"
2.1报错
Error running '__rvm_make install',
please read /Users/mac/.rvm/log/1655699107/openssl_make.install.log
2.1解决
rvm reinstall all --force
报错
Error running 'env GEM_HOME=/Users/mac/.rvm/gems/ruby-2.6.3@global GEM_PATH= /Users/mac/.rvm/rubies/ruby-2.6.3/bin/ruby -d /Users/mac/.rvm/src/rubygems-3.0.9/setup.rb --no-document',
please read /Users/mac/.rvm/log/1655699335_ruby-2.6.3/rubygems.install.log
解决
rvm remove ruby-2.6.3
rvm get head --autolibs=3
rvm requirements
rvm install ruby-2.6.3
rvm --default use ruby-2.6.3
3.更换源
sudo gem update --system
gem sources --remove https://rubygems.org/
gem sources --add https://gems.ruby-china.com/
报错
fatal: not in a git directory
Error: Command failed with exit 128: git
输入
brew -v
3.安装 cocoapods
sudo gem install cocoapods
执行 pod setup 出现 setup completed
pod setup
4.创建文件夹.cocoapods 和repos,创建.cocoapods时，需要打开显示隐藏文件夹cms+shift+.快捷键，然后创建
5.设置repos文件夹Git初始化，即，在repos文件路径下
pod repo remove master
cd ~/.cocoapods/repos
git init
git clone --depth 1 https://github.com/CocoaPods/Specs.git master
rm ~/Library/Caches/CocoaPods/search_index.json
pod search AFNetWorking
