Не удалось обновить Rails с 4.20 до 5.2.3

Question

Я пытаюсь обновить приложение rails 4.2 до 5.2.3.
Моя система MacOS 10.14.6 Mojave. Версия Bundler 2.0.2

Вот ошибка после того, как я bundle update:

Вот что я получаю, когда обновляю только rails bundle update rails:

Похоже, для actionpack, activerecord, activemodel и activesupport требуется версия 5.2.4.rc1. Вот мой местный драгоценный камень:

Xuans-MacBook-Pro:moldb xuan$ gem list "activesupport"

*** LOCAL GEMS ***

activesupport (6.0.1, 5.2.4.rc1, 5.2.3, 5.2.0, 5.1.6.1, 4.2.11.1, 4.2.10)
redis-activesupport (5.2.0, 5.0.7, 5.0.3, 4.0.0)
Xuans-MacBook-Pro:moldb xuan$ gem list "activemodel"

*** LOCAL GEMS ***

activemodel (6.0.1, 5.2.4.rc1, 5.2.3, 5.2.0, 5.1.6.1, 4.2.11.1, 4.2.10)
Xuans-MacBook-Pro:moldb xuan$ gem list "actionpack"

*** LOCAL GEMS ***

actionpack (6.0.1, 5.2.4.rc1, 5.2.3, 5.2.0, 5.1.6.1, 4.2.11.1, 4.2.10)
Xuans-MacBook-Pro:moldb xuan$ gem list 'railties'

*** LOCAL GEMS ***

railties (6.0.1, 5.2.4.rc1, 5.2.3, 5.2.0, 5.1.6.1, 4.2.11.1, 4.2.10)

Я пробовал различные способы решить эту проблему обновления;но не повезло. Удаление Gemfile.lock, затем do bundle install не работает для меня (что выдает ту же ошибку).
При обновлении любого приложения на Rails так печально, что ад зависимостей просто трудно решить.

Спасибо за любую помощь и предложения!
