Pod init 或 Pod update 出现以下错误

Question

I am unable to use pod install or update. I have installed the cocoapods again and updated gems as well. Is there any way this can be resolved. I have spent a day on this but no luck. This the error:

  Update all pods

Answer 1

just to be correct, you've already uninstalled and reinstalled the Cocoapods ? Because that solution always works for me.

Is this with Xcode or a different IDE?
