I looked at several versions of ruby in my. rvm/gems /, so I deleted the version except 2.5.6

rvm remove version number

I have seen that my rvm version number is too low. Update the rvm version

rvm get stable

Set ruby Version after update

rvm use 2.5.6

Check again

I didn't find any cocoapods. It's obvious that I have reinstalled the cocoapods. It's weird here. I don't know what I did to make the cocoapods installed the day before tomorrow

gem install cocoapods

Try pod install again Start Analyzing dependencies Problem solving
