ruby版本2.3.0

rails版本5.0.0.beta2

** GEMFILE **

运行捆绑安装后我看到：

 Bundler could not find compatible versions for gem "activemodel": In snapshot (Gemfile.lock): activemodel (= 5.0.0.beta2) In Gemfile: rails (= 5.0.0.beta2) was resolved to 5.0.0.beta2, which depends on activerecord (= 5.0.0.beta2) was resolved to 5.0.0.beta2, which depends on activemodel (= 5.0.0.beta2) rails (= 5.0.0.beta2) was resolved to 5.0.0.beta2, which depends on activerecord (= 5.0.0.beta2) was resolved to 5.0.0.beta2, which depends on activemodel (= 5.0.0.beta2) mongoid (~> 4.0.0) was resolved to 4.0.0, which depends on activemodel (~> 4.0) web-console (~> 3.0) was resolved to 3.1.1, which depends on activemodel (>= 4.2) 

运行bundle update将仅使用Gemfile中的gem来从头开始重建快照，这可以解决冲突。

Answer 1

截至几天前，您现在可以将它添加到您的gemfile中：

gem 'mongoid', git: 'https://github.com/mongodb/mongoid.git'

Answer 2

我遇到了同样的问题。 我将mongoid gem版本更改为6.1.0，运行bundle更新后一切正常。

 #mongoid gem gem 'mongoid', '~> 6.1.0' 

Answer 3

Mongoid on Rails有一个function分支5.在你的gemfile中添加它。

 gem 'mongoid', git: 'https://github.com/estolfo/mongoid.git', branch: 'MONGOID-4218-rails-5'
