MongoServerSelectionError：连接 ECONNREFUSED ::1:27017

Question

我正在使用 Mongo 5.0.1 和 Node 17.2.0 这是我的代码如果我想使用此代码连接 Atlas，它会成功运行，但是当我尝试连接本地数据库时，它会出现此错误。

const { MongoClient } = require("mongodb");

async function main(){
    const uri = "mongodb://localhost:27017";

    const client = new MongoClient(uri);

    try{
        await client.connect();
        await listDatabases(client);
    } catch (e){
        console.error(e);
    } finally {
        await client.close();
    }
}
main().catch(console.error);

async function listDatabases(client) {
    databasesList = await client.db().admin().listDatabases();

    console.log("Databases:");
    databasesList.databases.forEach(db => console.log(` - ${db.name}`));
};

这是我收到的错误。

使用它作为你的 uri

  const uri = "mongodb://127.0.0.1:27017";
