featureCompatibilityVersion必须为3.4才能使用整理

我需要在我的网站中整合英里/距离搜索，并且我正在使用mongodb地理空间索引，但是我收到了一些无法解决的问题。下面是我的架构和指令featureCompatibilityVersion必须为3.4才能使用整理

=> db.properties.findOne({},{address:1}) 
{ 
    "_id" : ObjectId("585b909c870d907845b695fd"), 
    "address" : { 
     "postcode" : "W1D 1NN", 
     "address1" : "Essence", 
     "address2" : "United Kingdom House", 
     "county" : "London", 
     "town" : "LONDON", 
     "latitude" : "51.5160229933117", 
     "longitude" : "-0.139088472429092", 
     "house_number" : "114", 
     "location" : { 
      "type" : "Point", 
      "coordinates" : [ 
       -0.139088472429092, 
       51.5160229933117 
      ] 
     } 
    } 
}

下面是我的指标

=> db.properties.getIndexes() 
[ 
    { 
     "v" : 1, 
     "key" : { 
      "_id" : 1 
     }, 
     "name" : "_id_", 
     "ns" : "cherrydoorsync.properties" 
    }, 
    { 
     "v" : 1, 
     "key" : { 
      "address.location.coordinates" : "2d" 
     }, 
     "name" : "address.location.coordinates_2d", 
     "ns" : "cherrydoorsync.properties" 
    } 
]

但是当我运行下面的蒙戈shell命令时，我得到错误

db.properties.aggregate([ 
    { 
    $geoNear: { 
     near: { type: "Point", coordinates: [ -2.94379156655216, 54.8905641133194 ] }, 
     distanceField: "dist.calculated", 
     maxDistance: 2, 
     includeLocs: "dist.location", 
     num: 5 
    } 
    } 
])

错误：

assert: command failed: { 
    "ok" : 0, 
    "errmsg" : "geoNear command failed: { ok: 0.0, errmsg: \"The featureCompatibilityVersion must be 3.4 to use collation. See http://dochub.mongodb.org/core/3.4-feature-compatibility.\", code: 72, codeName: \"InvalidOptions\" }",

有t他链接（http://dochub.mongodb.org/core/3.4-feature-compatibility）的错误信息，我这个链接，它建议设置setFeatureCompatibilityVersion to "3.4".，我运行该命令，并再次得到了一些其他错误

> db.adminCommand({ setFeatureCompatibilityVersion: <"3.4" }) 
2017-01-20T13:45:39.023+0530 E QUERY [main] SyntaxError: expected expression, got '<' @(shell):1:51

请帮我解决这个错误。

''db.adminCommand（{setFeatureCompatibilityVersion： “3.4”}）''命令成功执行，现在的 “featureCompatibilityVersion” 错误删除，将其投入另一个错误 '''“errmsg”：“geoNear命令失败：{ok：0.0，errmsg：\”无法获得查询执行程序\“}”， \t“code”：16604, \t“codeName”：“ Location16604“''' 我检查了这个链接（h ttp：//stackoverflow.com/questions/30240883/mongodb-cant-get-query-executor-when-executing-geonear-aggregate）但我只有一个索引'2d'而不是'2dsphere'如本链接所述。 –

尝试在2dsphere索引中删除2d。并添加您的请求'球形：true'。它应该工作：'db.properties.aggregate（[ {$ geoNear：{ 附近：{类型： “点”，坐标：[-2.94379156655216，54.8905641133194]}， distanceField： “dist.calculated”， maxDistance ：2， includeLocs： “dist.location”，民：5，球状：真 }} ]）' –

为我工作，谢谢 – AhammadaliPK

使用此在蒙戈外壳

db.adminCommand({ setFeatureCompatibilityVersion: "3.4" })
