【问题描述】：
运行 MacOS 10.13.6，MongoDb 存在巨大问题。 本质上是一个简单的终端 (mongo) 连接导致
MongoDB shell version v4.2.7
connecting to: mongodb://127.0.0.1:27017/?compressors=disabled&gssapiServiceName=mongodb
2020-06-09T18:31:51.654+0300 E QUERY [js] Error: couldn't connect to server 127.0.0.1:27017, connection attempt failed: SocketException: Error connecting to 127.0.0.1:27017 :: caused by :: Connection refused :

当 brew services 显示 mongodb-community 正在运行时。我试过停止它并手动运行 mongod（启动 mongodb 服务器）

这很奇怪，我试过停止brew服务，重新安装mongodb-community版等，都没有效果...无法连接数据库。
