unable to upgrade cocoapods 1.10
The new of cocoapods 1.10 is not let me upgrade on my Macbook pro
Cocoapods is not an Apple product and you should contact the developer for assistance. Also, see pod install vs pod update.
It would be nice if they clearly stated what the macOS system and ruby version requirements are.
Although the Cocoapods installation says it is compatible with the Ruby distributed by Apple in macOS, you shouldn't take that literally if you are actually running on macOS High Sierra. The Ruby that shipped with High Sierra is long since deprecated, and CocoaPods may be assuming you are on a newer version of Ruby. It is also a sudo installation.
