Mongoose: 错误：检测到循环依赖性

创建于 2018-02-08 · 40评论 · 资料来源: Automattic/mongoose

在macOS上运行最新版本的Node.js。还运行最新版本的猫鼬。

看到Error: cyclic dependency detected实际上无法调试。一切都指向猫鼬。有什么建议？今天开始发生。

因为“当前遇到相同的问题”太模糊而无法采取行动，因此将其锁定。请打开一个新问题，并遵循问题模板。

vkarpov15 于 2018-04-24

伙计们，我想我找到了原因-显然与mongodb 3.6有关（我最近从3.2升级到3.6，猫鼬也升级到了5.x）...

所以我再也无法运行我的应用程序了，我得到了这些循环依赖性错误...对我有用的唯一解决方法是将autoIndex: false到mongoose.connect -但是因此，即使稍后在应用程序上使用ensureIndex()之后，也不再创建我的索引-最终会导致相同的循环依赖项错误。

长话短说，我设法通过从模型内部删除所有属性INDEX并将其附加到模型中来解决问题，如下所示：

之前

client: { type: ObjectId, ref: 'tsCli', required: true, index: true },

后

client: { type: ObjectId, ref: 'tsCli', required: true },
[...]
Schema.index({ client: 1 });

并且，更重要的是，从复合索引中删除属性INDEX，即：

之前

Schema.index({ client: 1, code: 1 }, { unique: true, index: true, partialFilterExpression: { code: { $type: String } } });

后

Schema.index({ client: 1, code: 1 }, { unique: true, partialFilterExpression: { code: { $type: String } } });

希望这对别人有帮助

我在尝试在数组上添加索引时特别遇到了这个问题：

...
tags: {
  type: [String],
  index: true
}
...

只需将prop / index添加到我的架构中就会导致此问题

AndrewBarba 于 2018-05-02

嘿@AndrewBarba ..尝试像我提到的那样添加索引，而不是在字段上，而是在模式上，看看它是否有效

gustvao 于 2018-05-02

@gustvao我实际上首先尝试过，没有运气:(

AndrewBarba 于 2018-05-02

@AndrewBarba我有同样的问题。使用MongoClient我必须使用：

Collection.createIndexes([
    {
        key: { email: 1 },
        name: 'user_email',
        unique: true
    }
])

希望这可以帮助。

可能值得注意的是，我在$$$ mongodb+srv:// uri结构中使用了一些选项：

mongodb+srv://user:[email protected]?readPreference=primaryPreferred&retryWrites=true

一旦删除了uri选项，问题就消失了，而没有任何其他代码更改：

mongodb+srv://user:[email protected]

嗨@ vkarpov15 ，

删除Atlas的retryWrites有什么影响，这是猫鼬在内部进行的操作吗？

更新到最新的猫鼬版本后，我也收到此错误。我没有在任何架构中创建任何索引。现在我的应用程序太大了，我无法找出导致此问题的代码是什么。在Mongoose ^ 4.13.1上运行良好。

mykhaliuk 于 2018-06-02

使用@mykhaliuk的这段代码：

const mongoose = require('mongoose');
mongoose.set('debug', true);

const { Schema } = mongoose;

run().then(() => console.log('done')).catch(error => console.error(error.stack));

async function run() {
  await mongoose.connect('mongodb+srv://user:[email protected]/test?retryWrites=true', {dbName:'db-name'});

  const M = mongoose.model('Test', new Schema({ name: {type: String, unique: true }}));

  await M.create({ name: 'test' });
  console.log(await M.findOne());
}

我收到以下错误： Error: cyclic dependency detected

我发现维护retryWrites的唯一方法是使用mongodb API中的函数createIndexes ：

const mongoose = require('mongoose');
mongoose.set('debug', true);

const { Schema } = mongoose;

run().then(() => console.log('done')).catch(error => console.error(error.stack));

async function run() {
  await mongoose.connect('mongodb+srv://user:[email protected]/test?retryWrites=true');

  const M = mongoose.model('NewTest', new Schema({ name: {type: String} }));

  M.collection.createIndexes([{key: {name: 1}, name: "name", unique: true}])

  await M.create({ name: 'test' });
  console.log(await M.findOne());
}

所以我们要从猫鼬模型定义中删除unique ， index并使用createIndexes （https://docs.mongodb.com/manual/reference/command/createIndexes/）创建所有索引

我遇到了这个问题，也从Mongoose 4.11.7升级到5.1.4。我尝试从我的连接URI中删除?retryWrites=true ，但是不走运。最终，我发现我正在像这样的自定义_id属性上使用index:true ：

_id: {
    type: String,
    required: true,
    index: true
  }

删除index:true解决我的问题。还发现了提到解决方案的问题： https :

对我来说，当我的连接字符串中有retryWrites=true且模型中有Schema.index({ someKey: 1 })时，我遇到了这个问题。

在mongo shell中，执行db.adminCommand( { getParameter: 1, featureCompatibilityVersion: 1 } )返回{ "featureCompatibilityVersion" : { "version" : "3.6" } } 。

然后，我通过在mongo shell中执行db.adminCommand( { setFeatureCompatibilityVersion: "3.4" } ) ，将mongodb的featureCompatibilityVersion降级为3.4 ，并再次使用retryWrites=true和Schema.index({ someKey: 1 })来运行我的应用程序上文提到的。

确保成功创建索引后，我通过执行db.adminCommand( { setFeatureCompatibilityVersion: "3.6" } )将mongodb的featureCompatibilityVersion升级到3.6 db.adminCommand( { setFeatureCompatibilityVersion: "3.6" } ) ，然后再次运行我的应用程序。循环依赖性错误不再出现。

找到了问题。它与Atlas或retryWrites或featureCompatibilityVersion无关。它与尝试在_id上创建索引有关。最少的复制脚本：

const mongoose = require('mongoose');
mongoose.set('debug', true);

Error.stackTraceLimit = Infinity;

const { Schema } = mongoose;

run().then(() => console.log('done')).catch(error => console.error(error.stack));

async function run() {
  await mongoose.connect('mongodb://localhost:27017/test', {dbName: 'test'});

  const M = mongoose.model('Test', new Schema({ _id: { type: String, index: true } }));

  await M.create({ _id: 'abc' + Math.random() });
  console.log(await M.findOne());
}

为此将在mongodb驱动程序中打开PR

不错@ vkarpov15

我通过从连接字符串中删除retryWrites querystring来修复了我的问题。

之前
mongodb：// sa ：@ cluster0-shard-00-00-ljpyb.mongodb。网址：27017 ，cluster0-shard-00-01-ljpyb.mongodb。网址：27017 ，cluster0-shard-00-02-ljpyb.mongodb。净值：27017 / test？ssl = true＆replicaSet = Cluster0-shard-0＆authSource = admin＆ retryWrites = true

后
mongodb：// sa ：@ cluster0-shard-00-00-ljpyb.mongodb。网址：27017 ，cluster0-shard-00-01-ljpyb.mongodb。网址：27017 ，cluster0-shard-00-02-ljpyb.mongodb。净值：27017 / test？ssl = true＆replicaSet = Cluster0-shard-0＆authSource = admin

希望这可以帮助。

尝试删除_id @otisidev上的所有索引。因此，如果您有类似new Schema({ _id: {type: String, index: true} })或schema.index({ _id: 1 })请删除该内容。

@ vkarpov15我认为这里可能有两个问题。我在项目中的_id上没有任何索引，直到我从URI中删除?retryWrites ，仍然看到此错误。我将创建一个显示该项目的项目。无论如何，这似乎确实是mongodb驱动程序而非Mongoose的问题

@ vkarpov15这是一个产生此问题的脚本，在_id上没有任何索引：

猫鼬：v5.1.5
节点：v8.11.3

const mongoose = require('mongoose')
const { Schema } = mongoose

async function run() {
  try {
    await mongoose.connect('mongodb://localhost:27017/test?retryWrites=true', {
      dbName: 'mongoose-issue-6109'
    })

    const Model = mongoose.model('Model', new Schema({
      email: {
        type: String,
        index: {
          unique: true
        }
      }
    }))

    await Model.create({
      email: '[email protected]'
    })

    console.log(await Model.findOne())
  } catch(err) {
    console.error(err)
  }
}

run()

将索引字段设置为：

index: { type: 'hashed', unique: true }

也总是触发此问题

tschellenbach 于 2018-06-19

是的，这似乎是一个合法的问题-我已经在我的代码库中扫描了错误的索引，而且它似乎仍然会再次发生。降级为5.1.0 ，看来工作正常。

karthikiyengar 于 2018-06-20

我已经看到了错误。

_email _ ：{
类型：字符串，
必填：是，
_唯一：正确_
}，
.......

credentialSchema.index（{_ email_ ：1，域：1，ip地址：1，密码：-1}）;

我不得不从模型定义中删除唯一性。

otisidev 于 2018-06-20

@AndrewBarba感谢您的复制，我发现了另一个问题，例如node-mongodb-native＃1740，请参阅https://github.com/mongodb/node-mongodb-native/pull/1758 。一旦发布了新版本的mongodb驱动程序，此修复程序将以mongoose结尾。

使用地图集时遇到了相同的问题，但是在本地一切都很好。正如有人建议的那样，快速解决此问题的方法是删除参数?retryWrites=true ，现在一切正常。

应该在5.1.8中修复

vkarpov15 于 2018-07-03

我在MongoDB Atlas和GridStore上遇到了一些问题，直到删除了“ retryWrites = true”，写入操作才起作用。
