Question

我正在尝试从Ruby 2.3迁移到2.4.2，并将monogID 5.0迁移到5.2

我收到软件包更新错误。

我正在使用rbenv并在本地安装并设置2.4.2。

然后我不得不运行gem install bundler->它安装了2.0.1

然后我运行捆绑包更新，但出现此错误。

      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

我不确定该如何解决？

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）已解析为4.2.11，具体取决于
捆绑软件（<2.0，> = 1.3.0）

好像您使用的是rails 4.2一样，它需要使用旧版本的捆绑器

然后运行

bundle install

，您还需要解决其他一些依赖性

从2.3切换到2.4时，套件更新错误
