代码是：

db.collection('fruit').doc('46（数据缩减了，是_id）').remove({

success: function(res) {

console.log(res.data)

}

})

报错为：

Error: errCode: -1  | errMsg: document.remove:fail Error: cannot remove document with _id 46, please make sure that the document exists and you have the corresponding Write permission; at document.remove api; 

这个云数据库权限已设置为所有人可改动，求解，另外拜托大家教教用where指定条件删除
