Обновление с ruby ​​2.2.0 до 2.5

Question

У меня есть проект Rails (4.2.6), который был написан с использованием ruby ​​2.2.0.

Я пытаюсь перейти на ruby ​​2.5.Для этого я изменил в репозитории Rails файл .ruby-version на ruby-2.5.0.

В терминале версия ruby ​​верна:

ruby 2.5.0p0 (2017-12-25 revision 61468) [x86_64-darwin17]

Когда я запускаю

bundle update --bundler 

Я получаю следующую ошибку:

6 warnings and 2 errors generated.
make: *** [generator.o] Error 1

make failed, exit code 2

Gem files will remain installed in /Users/albert/.rbenv/versions/2.5.0/lib/ruby/gems/2.5.0/gems/json-1.8.3 for inspection.
Results logged to /Users/albert/.rbenv/versions/2.5.0/lib/ruby/gems/2.5.0/extensions/x86_64-darwin-17/2.5.0-static/json-1.8.3/gem_make.out

An error occurred while installing json (1.8.3), and Bundler cannot continue.
Make sure that `gem install json -v '1.8.3'` succeeds before bundling.

In Gemfile:
  rails was resolved to 4.2.6, which depends on
    actionmailer was resolved to 4.2.6, which depends on
      actionpack was resolved to 4.2.6, which depends on
        actionview was resolved to 4.2.6, which depends on
          rails-dom-testing was resolved to 1.0.7, which depends on
            rails-deprecated_sanitizer was resolved to 1.0.3, which depends on
              activesupport was resolved to 4.2.6, which depends on
                json

Я пытался вручную обновить гем json:

gem install json -v '1.8.3' 

Без успеха:

На данный момент я не знаю, что гуглить, как отлаживать.

Если я запускаю

bundle install

Я получаю следующую ошибку

    2: from ./bin/bundle:3:in `<main>'
    1: from /Users/albert/.rbenv/versions/2.5.0/lib/ruby/2.5.0/rubygems.rb:263:in `bin_path'

To update to the lastest version installed on your system, run `bundle update --bundler`.
To install the missing version, run `gem install bundler:1.14.3`

Не уверен, что это значит, что у меня в Gemfile.lock есть:

bundler (>= 1.3.0, < 2.0)

И, я мой Gemfile, у меня в качестве источника:

source 'https://rubygems.org'
```

As far as I understood, bundle is a gem manager that works on Mac, and bundler is a gem that manages gems?

Answer 1

Это потому, что у вас неправильные ресурсы самоцветов.

Попробуйте это исправить

gem sources -r  http://gems.rubyforge.org/
gem sources -r http://gems.github.com
gem sources -a https://rubygems.org/

Затем снова связывайте, как вы сделали
