CocoaPods could not find compati

$ pod repo update

$ sudo gem install cocoapods

sh-3.2# gem install cocoapods
ERROR:  While executing gem ... (Gem::FilePermissionError)
    You don't have write permissions for the /usr/bin directory.

sh-3.2# gem install cocoapods

sh-3.2# 

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

这样下来不如重装cocoapods

brew install ruby

然后咱们重启下，查看下ruby版本

AdministratordeMacBook-Air:~ administrator$ ruby -v
ruby 2.7.0p0 (2019-12-25 revision 647ee6f091) [x86_64-darwin18]
AdministratordeMacBook-Air:~ administrator$ 

然后发现是最新的版本

安装cocoapods

$ sudo gem install cocoapods

查看下cocoapods版本

AdministratordeMacBook-Air:~ administrator$ pod --version
1.7.5
