ReplicaSetNoPrimary MongooseServerSelectionError: getaddrinfo EAI_AGAIN mongodb-主数据库
我在码头安装了一个mongodb副本。当我使用cli连接到mongodb时，它工作得很好。但是，试图通过node.js使用猫鼬包连接到它会给出以下错误消息。

将此参数添加到连接字符串中：
directConnection=true如下所示：
mongodb://root:password123@localhost:27017/streamhatchet?directConnection=true&authSource=admin&replicaSet=replicaset&retryWrites=true参考文献：
