Vagrant problem

Подскажите пожалуйста, как правильно ораганизовать рабочую среду.

У меня есть простой проект https://github.com/Evanto/SleepCalc.
Я использую на Ubuntu 16.10 (GNU/Linux 4.8.0-49-generic x86_64) Vagrant c синхронизованной папкой для разработки. На сервере в irb косноли у меня виснет транзакция. Как я понимаю, 
мне нужна обратная синхронизация (или управляемая) чтобы можно было работать с консолью внутри гостевой машины.
Вот лог проблемы. Ведущая система руби конфликтует с частью пакетов и не может быть исполнена.

DEPRECATION WARNING: Time columns will become time zone aware in Rails 5.1. This
still causes `String`s to be parsed as if they were in `Time.zone`,
and `Time`s to be converted to `Time.zone`.

To keep the old behavior, you must add the following to your initializer:

    config.active_record.time_zone_aware_types = [:datetime]

To silence this deprecation warning, add the following:

    config.active_record.time_zone_aware_types = [:datetime, :time]
 (called from irb_binding at (irb):1)
