mongodb服务已经启动,但无法读取Connection.DEFAULT_PORT

Question

mongodb服务已经启动，浏览器可以访问localhost:27017,但是控制台还是报错 无法读取Connection.DEFAULT_PORT; 新手求大神解决

自己也百度找了好多文章，但是没有解决，不知道问题出在哪里，话说定义使用默认端口就是这样的啊，新手求助！

Answer 1

This actually has nothing to do with the MongoDB server itself. It is a problem with the driver.
You need to first determine what version of the driver you are using, whether it is native-driver or mongoose.
You probably saw the code from somewhere else. The main problem may be that the driver version you are using is different from others.
