Ruby on rails 让mongoDB使用Rails 4.1.1

我将进一步了解Rails开发web应用程序的“方式”（我有asp.net背景）。我想创建一个简单的应用程序，Rails作为大型机，MongoDB作为db，angularJS作为前端。但是现在我在让rails与MongoDB合作方面遇到了巨大的问题。我在我的文件中添加了以下内容：

gem 'rails', '4.1.1'
gem 'mongoid', github: 'mongoid/mongoid'

但是当我运行

bundle update

og

bundle install

时，我得到以下错误：

正如我所看到的，maeking mongoDB在使用Rails 4时存在多个问题，有人知道我做错了什么吗？或者我应该切换到其他noSQL数据库

我在上查看了Mongid，得到了以下信息：

版本4将支持Rails4，但尚未发布

---

只有

4.0.0.rc2,4.0.0.rc1,4.0.0.beta,4.0.0.alpha

看看这个，可以帮助您在Windows上安装

mongoid

。您可以尝试在文件中强制执行

4.0.0.rc2

。
