有两个问题请教大家： 腾讯云天天提醒我有个环境欠费了，在哪里删除环境啊？怎么查询一个小程序使用和关联的所有环境呢？

想把数据存成excel文件，百度了说需要安装node-xlsl，但我这边一直安装失败。安装步骤如下： 1.新建一个node-js云函数excel2 2.在excel2右键点“内建终端打开” [图片] 3.在终端中运行：npm install node-xlsl，报错 PS D:\10-My Doc\06-微信小程序\00-我的小程序\05-自习室0328\cloud\excel2> npm install node-xlsl npm WARN package.json excel2@1.0.0 No description npm WARN package.json excel2@1.0.0 No repository field. npm WARN package.json excel2@1.0.0 No README data npm ERR!

数据库中有两个集合：adminList { "_id":str, "isAdmin":boolean, "managerOfShop":[], "_openid":{openid}, "admin":{openid} } draftUserInfo {"_id":str," _openid":{openid}, "cardNo":str, "isNew":boolean, "nickName":str, "phoneNo":str, "shops":[] } 2.想实现对draftUserInfo的访问规则为：只有集合admin里的管理员（根据isAdmin或者admin字段判断）可读 3.对draftUserInfo设了下面两个安全规则都不生效，读不出数据 { "read": "auth.openid==get('database.adminList.${doc._id}').admin", "write": "doc._openid == auth.openid" } 设下面规则时，还必须加上"==true"，否则报错 { "read": "get('database.adminList.${auth.openid}').isAdmin==true", "write": "doc._openid == auth.openid" } 折腾了一天也不知道怎么回事，请各位指点迷津，多谢了 代码片段 db.collection('draftUserInfo').where({ _openid:openid,isNew:true }).get({ success: function(res) { var ui=res.data that.setData({ userInfo:ui })
