有人可以帮助我了解为什么会出现此错误以及解决方法是什么吗？

1. 在您的 package.json Mongoose 有一个更高的版本 4.0.0。但是 mongoose-simpledb 需要 mongoose@~3.8.18。

2. mongoose-simpledb 包含它的依赖项 mongoose-auto-increment。如果您在模式中显式声明 _id 字段为 Number 类型，那么 simpledb 将自动为该模型调用 mongoose-auto-increment 插件。

文档本身的示例:

exports.schema = {
    _id: Number, // Causes simpledb to auto-increment _id for new documents.
    creator: { type: Number, ref: 'User' }
};

我已经尝试将 package.json 更改为此并且它有效:
