我在用,
“猫鼬”:“^5.8.1”
即使我降级到Mongoose版本5.6.13,弃用警告也会消失,但以下错误仍然存在-

超时。(/home/gaurav/Downloads/Assignments/DevConnection_2.0/node_modules/mongodb core/lib/topologies/mongos.js:736:28)

不降级
您能在useNewUrlParser:true
旁边添加这一行,然后再次运行吗
useUnifiedTopology: true
您的代码应该如下所示
db = "mongodb+srv://<username>:<password>@devconnector-sk8na.mongodb.net/test?retryWrites=true&w=majority"
try{
await mongoose.connect(db, { useNewUrlParser: true})
console.log("MongoDB Connected..")
} catch(err){
console.error(err);
process.exit(1);
}
db = "mongodb+srv://<username>:<password>@devconnector-sk8na.mongodb.net/test?retryWrites=true&w=majority"
try{
await mongoose.connect(db, { useNewUrlParser: true, useUnifiedTopology: true })
console.log("MongoDB Connected..")
} catch(err){
console.error(err);
process.exit(1);
}
db=“mongodb+srv://:@devconnector-sk8na.mongodb.net/test?retryWrites=true&w=mailty”
试一试{
wait mongoose.connect(db,{useNewUrlParser:true,useUnifiedTopology:true})
console.log(“MongoDB已连接…”
}捕捉(错误){
控制台错误(err);
过程。退出(1);
}
这是否回答了您的问题?看看这个答案,没用!!我试图降级到猫鼬的旧版本,但它仍然无法连接。我收到错误“MongoError:没有可用的mongos代理”@shreyanzhain
db = "mongodb+srv://<username>:<password>@devconnector-sk8na.mongodb.net/test?retryWrites=true&w=majority"
try{

} catch(err){
console.error(err);
process.exit(1);
