从 2.3 切换到 2.4 时出现包更新错误

Question

我正在尝试从 Ruby 2.3 移动到 2.4.2 并将 monogID 5.0 移动到 5.2

我收到捆绑包更新错误。

我正在使用 rbenv 并在本地安装和设置 2.4.2。

然后我运行不得不运行 gem 安装 bundler -> 它安装了 2.0.1

然后我运行捆绑包更新，我得到了这个错误。

      Bundler could not find compatible versions for gem "bundler":
    In Gemfile:
      iron_worker_ng was resolved to 1.6.10, which depends on
        bundler

      rails (~> 4.2) was resolved to 4.2.11, which depends on
        bundler (< 2.0, >= 1.3.0)

    Current Bundler version:
      bundler (2.0.1)
  This Gemfile requires a different version of Bundler.
  Perhaps you need to update Bundler by running `gem install bundler`?

  Could not find gem 'bundler (< 2.0, >= 1.3.0)', which is required by gem 'rails
  (~> 4.2)', in any of the sources.

  Bundler could not find compatible versions for gem "mongoid":
    In Gemfile:
      mongoid (~> 5.2)

      mongoid-encrypted-fields was resolved to 1.2.2, which depends on
        mongoid

我不知道如何解决这个问题？

Answer 1

您需要做的第一件事是安装兼容版本的捆绑器

gem install bundler -v '~> 1.17'

rails (~> 4.2) was resolved to 4.2.11, which depends on
bundler (< 2.0, >= 1.3.0)

似乎您使用的是 rails 4.2，它需要旧版本的捆绑器

然后运行

bundle install

您还需要解决其他一些依赖关系
