Question

我正在处理从Github https://github.com/MessagingBots/MessengerBot下载的回购，我知道js代码没问题。

我有一个配置文件，将db URL指向＆＃34; mongodb：//127.0.0.1：27017 / messenger＆＃34;。（我还没有创建数据库）

我在Heroku上有节点应用程序，但每次在mongodb connect上Heroku Logs失败。

我正在运行mongod个实例。 mongod正确连接到localhost并且稳定

问题可能与猫鼬有关。

有人可以帮帮我吗？

Answer 1

查看是否存在旧锁定文件（如果存在），而不是将其删除 sudo rm /var/lib/mongodb/mongod.lock看看这是否适合你 sudo mongod --repair and（sudo start mongodb或sudo service mongodb start）

Answer 2

你的mongoose connect call中没有精确的mongodb：//：

mongoose.connect("localhost:27017/mydbname");

Mongoose无法连接到localhost：MongoError：无法连接到服务器[127.0.0.1:27017]
