云数据库查询 elemMatch　为什么编译不通过？-我爱小程序

TypeError: _.elemMatch is not a function

我代码有么问吗？

table.field({

_id: true,

profiles: true

}).where({

profiles: _.elemMatch(

{ age: _.gt( 10 ), name: _.neq(null) } )

}) .get();

我的开发工具版本 Stable v1.02.1907300

project.config.json 设置 "libVersion": "2.8.1"

为什么编译不过呢？
