'autoIndexID'不是有效的收集选项-mongoDB [英] 'autoIndexID' is not a valid collection option - mongoDB

问题描述

当我尝试在我的MongoDB上运行它时:

When I try to run this on my MongoDB:

db.createCollection("mycol", { capped : true, autoIndexID : true, size : 6142800, max : 10000 } )

我明白了:

{
    "ok" : 0,
    "errmsg" : "The field 'autoIndexID' is not a valid collection option. Options: { capped: true, autoIndexID: true, size: 6142800.0, max: 10000.0 }",
    "code" : 72,
    "codeName" : "InvalidOptions"
}

我不明白...对不起，如果它愚蠢. :/

I just don't get it... Sorry if it's dumb. :/
