使用 M1 Mac 上的 express 连接到 MongoDb 无法正常工作

Question

我用

安装了 mongoDB

brew install mongodb-community@5.0

我从 mongoDB 开始

brew services start mongodb-community@5.0

在 brew services list 我得到：

Name              Status  User        File
emacs             stopped
mongodb-community started laurenz ~/Library/LaunchAgents/homebrew.mxcl.mongodb-community.plist
unbound           stopped

在我的快速服务器上，我使用此代码连接到 mongoDB:

connectToServer: function (callback) {

mongoose.connect('mongodb://localhost/test', { useNewUrlParser: true });
const db = mongoose.connection
db.on('error', (error) => { 
  console.error(error)
  callback(error)
})

}

打开 MongoDB Compass 时，我可以连接到 MongoDB 并且还可以看到我的 table。相同的代码在我的 Intel iMac 上运行得很好。

这是我在启动 server.js:

时遇到的错误

Node.js v17.0.1
[nodemon] app crashed - waiting for file changes before starting...

有没有人有类似的问题或知道如何解决这个问题？

Answer 1

所以我想出了问题所在。

我将连接调用替换为：

MongoClient.connect('mongodb://127.0.0.1:27017', (err, client) => {
  if (err) return console.error(err)
  console.log('Connected to Database')

  console.log(client);
})

这似乎可行。我不知道为什么它不能与 localhost 一起使用，但现在它正在工作。
