Error adding iOS platform to the project

My project run fine on browser, but when I try add platform iOS, I get this error:

From version 2.4.5, the cordova-plugin-googlemaps uses CocoaPod.
No longer necessary com.googlemaps.ios plugin.

        Re-running this command with the --verbose flag may provide more information.

Apparently the problem is “cordova-plugin-googlemaps”

I have removed the platform. Then added CocoaPods ($ “sudo gem install cocoapods”), then add:

export LANG=en_US.UTF-8

but I still getting the error.

What is wrong? Can you help me?
