颤振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？

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

rvm install ruby-2.6

rvm use ruby-2.6.5

rvm --default use 2.6.5

sudo gem install cocoapods
