Error: failed to connect to [localhost:27017]

Question

当我运行 node app.js 时，出现以下错误：

Failed to load c++ bson extension, using pure JS version
Express server listening on port 3000
events.js:85
      throw er; // Unhandled 'error' event
            ^
Error: failed to connect to [localhost:27017]
    at null.<anonymous> (/Users/me/development/node_modules/mongodb/lib/mongodb/connection/server.js:553:74)
    at emit (events.js:118:17)
    at null.<anonymous> (/Users/me/development/node_modules/mongodb/lib/mongodb/connection/connection_pool.js:140:15)
    at emit (events.js:110:17)

    at Socket.emit (events.js:107:17)
    at net.js:451:14
    at process._tickCallback (node.js:355:11)

我不确定这是本地主机问题还是与 mongodb 的连接问题。我试着查看类似的问题 SO 和 Github 但它对我没有帮助。

似乎 mongodb 服务器不是运行。检查一下
