flutter 医生 - CocoaPods 已安装但无法正常工作

Question

使用 zsh - 用于在 bash 中工作
brew doctor - 您的系统已准备好进行 brew 。
flutter 医生给出了这个错误

[!] Xcode - develop for iOS and macOS (Xcode 12.2)
    ✗ CocoaPods installed but not working.
        You appear to have CocoaPods installed but it is not working.
        This can happen if the version of Ruby that CocoaPods was installed with is different from the one being used to invoke it.
        This can usually be fixed by re-installing CocoaPods. For more info, see https://github.com/flutter/flutter/issues/14293.
      To re-install CocoaPods, run:
        sudo gem install cocoapods  

sudo gem 安装 cocoapods

Gives this error  
dyld: Library not loaded: /usr/local/opt/gmp4/lib/libgmp.3.5.2.dylib  
  Referenced from: /Users/puser/.rvm/rubies/ruby-2.5.1/bin/ruby  
  Reason: image not found  
zsh: abort      sudo gem install cocoapods  

我无法纠正上述错误 - 有什么建议吗？
哪个 pods

/Users/puser/.rvm/rubies/ruby-2.5.1/bin/pod

哪个 gem

gem () {
    \typeset result
    (
        \typeset rvmrc
        rvm_rvmrc_files=("/etc/rvmrc" "$HOME/.rvmrc") 
        if [[ -n "${rvm_prefix:-}" ]] && ! [[ "$HOME/.rvmrc" -ef "${rvm_prefix}/.rvmrc" ]]
        then
            rvm_rvmrc_files+=("${rvm_prefix}/.rvmrc") 
        fi
        for rvmrc in "${rvm_rvmrc_files[@]}"
        do
            [[ -s "${rvmrc}" ]] && source "${rvmrc}" || true
        done
        unset rvm_rvmrc_files
        command gem "$@"
    ) || result=$? 
    hash -r
    return ${result:-0}
}

哪个 ruby

/Users/puser/.rvm/rubies/ruby-2.5.1/bin/ruby

根据这篇文章的建议，我能够使用以下命令重新安装 cocoapods
gem native extension error while installing cocoapods
打开终端

curl -L https://get.rvm.io | bash -s stable

重新打开终端

rvm install ruby-2.6

rvm use ruby-2.6.5

rvm --default use 2.6.5

然后这按预期安装了 cocoapods

sudo gem install cocoapods
