GYB: Command PhaseScriptExecution failed with a nonzero exit code

[ASwiftUser]

I am using GYB to test it and have made the following code:

//
//  test.swift.gyb
//  gyb_test
//
//  Created by Ethan Uppal on 1/17/19.

import Foundation

%{ abilities = ['strength', 'dexterity', 'constitution',
                'intelligence', 'wisdom', 'charisma']
}
class Character {
    var name: String
    
    % for ability in abilities:
    var ${type}: Int
    % end
}

However, when I try to build I get the following error:

[Alejandro (Alejandro Alonso)]

I believe it should be var ${ability}: Int

The script phase that you have set up to invoke the gyb script appears to have a placeholder for the path (line 5: ./path/to/gyb). Replace that path in your script with the actual path to the gyb executable script.

I put ./Documents/gyb and still not working

[scanon (Steve Canon)]

./Documents/ is a pretty weird path--that expands to (whatever the current working directory is)/Documents/gyb. Where is the gyb script you're trying to invoke?

Documents/gyb.py
