Wordpress WordMoveでpushできない

wordpressのデプロイにwordmoveが便利ということで試しに使っているのですが、wordmove push -e production --allを実行すると以下のエラーがでます。

ググってもなかなか解決に至る情報にありつけないので、お分かりになられる方がいましたら助言いただけるとありがたいです。
:SyntaxErrorってでてるから構文エラー？wordmoveが動作する要件に対して、ruby2.4.0はそれを満たしていないってことなのか？とか思っています。

この記事を参考にやっています。
ちなみにvagrantではなくMAMPでやっています。
