Question

作为Rails升级的一部分，我运行了bundle update rails。我对输出有些困惑。

Bundler could not find compatible versions for gem "activemodel":
  In Gemfile:
    mongoid was resolved to 6.1.1, which depends on
      activemodel (~> 5.0)

    rails (= 5.0.7.2) was resolved to 5.0.7.2, which depends on
      activemodel (= 5.0.7.2)

5.0.7.2不满足(~> 5.0)吗？

类似地：

Bundler could not find compatible versions for gem "rails":
  In Gemfile:
    rails (= 5.0.7.2)

    minitest-spec-rails was resolved to 5.5.0, which depends on
      rails (>= 4.1)

在这种情况下：5.0.7.2应该满足rails (>= 4.1)。

我不确定我在这里缺少什么。任何帮助将不胜感激。

rails升级可能是一团糟...您可以尝试将每个gem添加到“捆绑更新”调用中...当我从5.0.7.2更新到6.1.6时，我最终遇到了这个问题... < / p>

捆绑包更新bootstrap-kaminari-views devise_lastseenable皮革simple_calendar where_exists rspec-expectations rspec-rails prawnto_2 validates_overlap slim-rails active_model_serializers grape-active_model_serializers jbuilder has_scope spring-commandsrrspec pluck_tomin_hash >

所以，您可以先做

另外，您可能需要检查您的gem的哪个版本与要安装的rails版本兼容，因此您可能必须将某些gem“锁定”到某个版本，才能使更新成功
