Ionic Pro: iOS build failed

Hi everyone,

I have been trying to build my IOS app with ionic pro for days now, and i can’t find any solution. I did follow the instructions on that link: https://ionic.zendesk.com/hc/en-us/articles/115012555828-Ionic-Pro-Package-iOS-builds-failing-

First of all, my first test build failed because of the OneSignal Cordova plugin with that error :
Failed to install ‘onesignal-cordova-plugin’: undefined
Failed to restore plugin “onesignal-cordova-plugin” from config.xml. You might need to try adding it again. Error: CocoaPods was not found. Please install version 1.0.1 or greater from https://cocoapods.org/.

I tried the 2.2.0 version and the 2.1.0 nothing changed.

Next, i commented the line in the config.xml to check if the build really failed because of that plugin, and it did since the building process was going further but i had other errorS :
the first one :
02:41:40]: Exit status: 1
[02:41:40]: Your shell environment is not correctly configured
[02:41:40]: Instead of UTF-8 your shell uses US-ASCII
