当我尝试在本地连接到 Mongodb 时，发生了以下错误。
MongoDB shell version v3.6.4
connecting to: mongodb://127.0.0.1:27017

我在互联网上浏览了一些解决方案，其中一些告诉我尝试先在一个终端中运行 mongod，然后在另一个终端中运行 mongo。我正在使用 Windows，我在命令提示符下执行了这个过程。
当我首先尝试运行 mongod 时遇到以下错误 -

我尝试卸载并重新安装 mongodb，但它被存放在这里。需要你的帮助。
最佳答案
Mongod 没有启动，因为数据路径不存在或不可访问。
exception in initAndListen: NonExistentPath: Data directory C:\data\db\ not found
创建目录应该可以解决问题。
