node.js – MongoError：写EPIPE

2023年9月17日 326次阅读

我正在使用Node.JS Mongoose MongoDB.我的应用程序到目前为止工作正常,现在在尝试保存文档时：

保存操作：

doc.save(function(err, d){
    console.log(err,d);

{“name”:”MongoError”,”message”:”write EPIPE”}

错误堆栈：

{ [MongoError: server localhost:27017 received an error {"name":"MongoError","message":"write EPIPE"}]
  name: 'MongoError',
  message: 'server localhost:27017 received an error {"name":"MongoError","message":"write EPIPE"}' } undefined
error: TypeError: Cannot read property 'url' of undefined

    at next_ (/home/ec2-user/c/node_modules/mongoose/node_modules/hooks-fixed/hooks.js:75:26)

看起来我能够读取数据,但不能写新文档. Mongo是app并且正在运行.到目前为止,我已经尝试过,重新启动数据库,没有任何好结果.

刚尝试从mongo客户端插入并工作

> db.mysecretcollection.insert({url:"sampletestremoveme"});
WriteResult({ "nInserted" : 1 })

所以它似乎是一个Node.js / Mongoose问题.

最佳答案 在我看来,文档太大了,实际上我可以在删除其中一个字段后保存它.奇怪的是,mongoose应该捕获“错误：文件超过最大允许的bson大小XXX字节”异常,但是从未抛出过.
