无法使用干净的数据目录 UserNotFound 启动 MongoDB 的全新安装
Cannot start a clean installation of MongoDB with a clean data directory UserNotFound
TLDR：由于 UserNotFound 错误（未找到的用户来自旧安装），我无法使用空数据目录启动 Mongo（来自 ZIP）的全新安装。
更详细地说：我的初始 Mongo 数据库运行良好。出于测试目的，我移动了当前数据目录并创建了一个新目录。所以我用
停止了我的 运行ning Windows 服务
mongod --dbpath=C:\data\db --remove
创建了一个新的数据目录并尝试以
以 noauth 模式启动一个新的 MongoDB
mongod --dbpath=C:\data\db --noauth
麻烦从这里开始：MongoDB 尝试连接我旧数据库中的用户，而当前设置中未提及该用户。这是日志
