Mongodb events.js:85

Question

我一直在做这个项目。我面临着一些问题，我无法解决后，我真的很努力。如果你们能帮我，我会很感激的。我试图连接到mongodb数据库使用node.js，但每当我启动服务器，我得到以下错误。我不知道如何解决这个错误。

{ [Error: Cannot find module '../build/Release/bson'] code: 'MODULE_NOT_FOUND' }
js-bson: Failed to load c++ bson extension, using pure JS version
The magic happens on port 8080
Connected correctly to server
events.js:85
      throw er; // Unhandled 'error' event
            ^

感谢您的宝贵时间和考虑

Answer 1

您确定在系统本地启动并运行mongodb吗?

要将本地路径映射到mongodb，请尝试以下命令

[location of mongodb]/bin/mongod——dbpath "specify location of database"

Answer 2

您是否像下面这样编写代码?

mongoose.connect(configDB.url); // connect to database

我猜你没有设置你的configDB。url。

用您的db url设置它，如'localhost:27017/myDatabase'
