我已經嘗試了 2 多個小時，試圖找出這個資料庫出了什么問題。我什么都試過了。從重新安裝服務器，重新啟動行程，重新啟動等等。嘗試連接時它一直給我這個錯誤：
const serverSelectionError = new ServerSelectionError();

無論我做什么，這個錯誤都不會解決。MongoDB 服務器正在運行，我通過執行 >show dbs 進行了檢查，它完美地列出了它們。此外， C:/data/db 存在并且它也很好。我該怎么辦？這是我的連接代碼：
(async () => {
await require('./other/DB/mong')();
console.log("Connected to Database.");
})();
這是./other/DB/mong：
var mongoose = require("mongoose");
module.exports = async () => {
await mongoose.connect('mongodb://localhost:27017/MX', {
keepAlive: true,
useNewUrlParser: true,
useUnifiedTopology: true
});
return mongoose;
}
uj5u.com熱心網友回復：
默認情況下，MongoDB 不系結到 localhost 或 ipv6。
如果您希望它在 ::1 上偵聽，則需要啟用net.ipv6并啟用net.bindIpAll或在net.bindIp 中明確列出環回地址
