Question

我无法在mongodb版本3.0.12中执行upsert查询，而ruby gem版本为1.x。我使用ruby版本1.9.3。我尝试将mongodb升级到版本3.2和3.4，但仍面临同样的问题。如果有人知道发生了什么或遇到类似的问题，请提供一些见解。

mongo-ruby-driver 1.x根据https://www.mongodb.com/blog/post/announcing-ruby-driver-20-rewrite不完全支持mongodb 3：

升级到mongo gem版本2.0和mongoid gem版本5.0有很多原因，当它发布时。首先，这些版本支持MongoDB 3.0 [...] 不会添加新功能，开发工作将仅包含错误修复和支持最新版本服务器所需的最少功能。

我在整个互联网上搜索了有类似问题的人，我发现的唯一的人是pagerbot，他们使用1.x系列的gem和mongo 3并得到与你完全相同的错误：

他们通过更新到mongo-ruby-driver解决了这个错误.2。为了让你与这些依赖关系搏斗而道歉，但我找不到更简单的答案。
