文章描述了在编译过程中遇到的could未被声明的错误，该错误源于云函数login.js中将`cloud.database()`误写为`could.database()`。修复方法是改正这个拼写错误并重新上传部署云函数。清除缓存并重新编译后，问题得到解决，信息成功存储到云开发数据库。

问题：

在编译的过程中，点击注册/登录，出现问题，错误结果显示‘could’未被声明。

云函数文件夹cloud中的login.js文件部分代码:

// 云函数入口函数
exports.main = async (event) => {
  const { nickName, avatarUrl } = event
  const {OPENID} = cloud.getWXContext()
  /**对用户信息进行判断，有则用户则登录，反之注册 */
  /**1.初始化集合 */
  const db =could.database()

  /**2.指定集合 */
  const userInfo = db.collection('userInfo')

  /**数据库内新增数据 */
  const data = await userInfo.add({
    data:{
      nickName,
      avatarUrl,
      money: 0,
      loveValue: 0,
      message: 0,
      _openid:OPENID 
    }
  })

 return {
    data,
    // event,
    // openid: wxContext.OPENID,
    // appid: wxContext.APPID,
    // unionid: wxContext.UNIONID,
  }
}

小程序中me.js文件部分代码:

  /**用户授权 */
  async getUserInfo() {
    /**1.用户授权获取信息 */
    const {
      userInfo:{ nickName,avatarUrl }
    } = await wx.getUserProfile({
      desc: '用于完善用户信息',
    })
    /**2.把当前用户信息交付给后端，存储生成账号 */
    wx.cloud.callFunction({
      name:'login',
      data:{
        nickName,
        avatarUrl
      }
    })
  },
