MongoDB 4.4已停止在Windows 10计算机上启动

我已经在Windows10机器上安装了MongoDB4.4，运行良好。我可以从MongoDB compass连接它。但现在，当我尝试连接时，会出现“mongodb compass connect Econrefuse127.0.0.1:27017”错误。因此，我尝试通过执行mongod命令手动启动它，并看到以下跟踪：

这里的原因是什么

在配置文件storage.dbpath中设置为“C:\Program Files\MongoDB\Server\4.4\data”

# Where and how to store data.
storage:
  dbPath: C:\Program Files\MongoDB\Server\4.4\data

---

不存在路径：数据目录C:\\Data\\db\\

您需要创建该文件夹。或者在配置文件中更改它，并使用此文件：

mongod--config mongod.conf

---

请记住，对于运行mongod的用户，此文件夹必须是可写的。

在配置文件中，提到了db目录。
