RAILS: невозможно изменить замороженный SystemStackError (FrozenError) после обновления до Ruby 2.5.3

Question

Ошибка появляется после обновления с Ruby 2.2 до последней Ruby 2.5.3 для моего приложения Rails 4.2.0.Стоит ли использовать более старую версию Ruby?

Вот корзина / рельсы:

#!/usr/bin/env ruby.exe
APP_PATH = File.expand_path('../../config/application', __FILE__)
require_relative '../config/boot'
require 'rails/commands'      <==caused error above

Answer 1

Вы можете попробовать либо обновить до последней версии Rails 4.2 , либо использовать версию Ruby, более раннюю, чем 2.3 ( введение Frozen_string_literal pragma ).Если ни один из этих способов не работает, посмотрите на трассировку стека и попытайтесь определить, пытаетесь ли вы изменить замороженный объект.
