Updating rubygems-update
Fetching rubygems-update-3.6.8.gem
ERROR: Error installing rubygems-update:
invalid gem: package is corrupt, exception while verifying: wrong number of arguments (given 2, expected 1) (ArgumentError) in /Users/xxx/.rvm/rubies/ruby-3.0.0/lib/ruby/gems/3.0.0/cache/rubygems-update-3.6.8.gem
ERROR: While executing gem ... (NoMethodError)
undefined method `version' for nil:NilClass
解决办法：
# 通过homebrew安装ruby
brew install ruby --verbose
查看本地ruby的安装目录
~ which -a ruby
/opt/homebrew/opt/ruby/bin/ruby
/usr/bin/ruby
查看当前使用的ruby版本
ruby -v
系统自带ruby，如果发现当前使用的是系统自带的ruby，可以通过配置.zshrc环境变量来修改成使用安装的ruby版本
~ echo 'export PATH="/opt/homebrew/opt/ruby/bin:$PATH"' >> ~/.zshrc
~ source ~/.zshrc
这里的/opt/homebrew/opt/ruby/bin就是~ which -a ruby命令列出来的ruby的安装地址
也可以使用vim编辑器去编辑.zshrc
~ echo 'export PATH="/usr/local/opt/ruby/bin:$PATH"' >> ~/.zshrc
~ export LDFLAGS="-L/usr/local/opt/ruby/lib"
~ export CPPFLAGS="-I/usr/local/opt/ruby/include"
~ export PKG_CONFIG_PATH="/usr/local/opt/ruby/lib/pkgconfig"
~ source ~/.zshrc
重新执行命令sudo gem update --system即可

Ruby Interactive (ri) documentation was installed. ri is kind of like man
pages for Ruby libraries. You may access it like this:
ri Classname
ri Classname.class_method
ri Classname#instance_method
If you do not wish to install this documentation in the future, use the
--no-document flag, or set it as the default in your ~/.gemrc file. See
'gem help env' for details.

安装或更新cocoapods
查看cocoapods版本
pod --version
安装cocoapods:
sudo gem install -n /usr/local/bin cocoapods
更新cocoapods:
sudo gem update cocoapods
如果安装了多个Xcode使用下面的命令选择（一般选择较新的版本）
sudo xcode-select -switch /Applications/Xcode.app/Contents/Developer
安装本地repo仓库
# 官方命令，已失效
pod setup
# 使用克隆命令安装，需科学上网
git clone https://github.com/CocoaPods/Specs.git ~/.cocoapods/repos/trunk
# 使用国内镜像
git clone https://mirrors.tuna.tsinghua.edu.cn/git/CocoaPods/Specs.git ~/.cocoapods/repos/trunk
更新本地repo仓库:
pod repo update
或者
pod install --repo-update
安装或更新本地repo仓库可能会需要比较长的时间。本地仓库更新完成后，一般即可搜索到指定的第三方库，如果仍然搜索不到，可删除cocoapods的搜索缓存后重试
rm ~/Library/Caches/CocoaPods/search_index.json
cocoapods卸载当前版本：
sudo gem uninstall cocoapods
cocoapods下载指定版本：
sudo gem install cocoapods -v 1.16.1
