Я пытался обновить через:

bundle update rails
gem install rails -v 5.0.2
gem update rails

Rails 4.2.0 version
ruby 2.4.4p296 (2018-03-28 revision 63013) [x86_64-linux]

Я получаю много ошибок при запуске рельсов. Я посмотрел в интернете, что мне нужно обновить, но без успеха

Answer 1

Rails-4 предпочитает Ruby 2.0 и требует 1.9.3 или новее. Rails-5 требует Ruby 2.2.2 или новее.

Ваша версия Rails довольно старая, обновите ее до

gem upgrade rails

Если у вас уже есть проект Rails

1. Укажите нужную версию в своем Gemfile
2. Выполнить bundle install / bundle update
3. Выполнить rails app:update

лучше следите это
