如何将 Rails 7 的机架升级到 v3？

Question

如何将rackRails 7 的 gem 从 v2 升级到 v3？

如果您尝试使用：

gem 'rack', '>= 3'

Bundle 将显示升级结果：

Bundler could not find compatible versions for gem "rack":
  In Gemfile:
    rack (>= 3)

    rails (~> 7.0.4) was resolved to 7.0.4, which depends on
      actionpack (= 7.0.4) was resolved to 7.0.4, which depends on
        rack (~> 2.0, >= 2.2.0)

2023 年初，v7.0 无法升级rack到 v3，rails因为尚未准备好。请关注此 PR 以获取有关正在进行的流程的最新信息：
