迁移到 Rails 5，rails gem 问题

Question

我正在尝试从 Rails 4.2 迁移到 Rails 5.0（运行在 ruby 2.3 上）（在此处查看计划）

计划是：

更新 rails gem 和所有依赖项。
运行测试（几乎涵盖我们的整个代码库）折旧并修复它们。
运行 rake rails:update 到 update Rails
调整配置、应用程序类、重大更改、...

然而，我在第一步就被阻止了，更新 rails gem 和依赖项。 gem 'rails', '4.2.5' -> gem 'rails', '~> 5.0' 运行: bundle update rails.

我遇到了多个依赖项问题，我通过查找最终要求 rails 小于 5 的任何依赖项来解决这些问题，并查看是否可以更新这些依赖项。运行宁：

bundle update rails tolk rspec-rails globalize active_model_serializers simple_form postmark-rails > rails_update_report.txt

我最终得到一个 Gemfile 如下：

Answer 1

听起来您已经控制了 "look for a blocking dependency, then fix it" 周期。

目前需要关注的在最下面：

rails-i18n (>= 4.0.8, ~> 4.0) was resolved to 4.0.9, which depends on
  railties (~> 4.0)

Answer 2

IMO 将版本号和范围保留在 Gemfile 之外并且仅在 Gemfile.lock 中是很好的。这样一来，您只需查找一个地方即可解决这些问题。所以，当你添加一个 gem 时，继续将它和它的版本规范放在 Gemfile 中，执行 bundle install 并安装它，然后从 Gemfile 中删除版本规范并离开它在 Gemfile.lock 中，捆绑程序会自动将其放入其中。
