Mysql 錯誤 - 1251 'ER_NOT_SUPPORTED_AUTH_MODE'

Question

我知道這個問題已經在 SO 中得到解答，但是建議的修復對我不起作用！

錯誤：

      throw err; // Rethrow non-MySQL errors
      ^

我有一個 Xampp 服務器與本地主機上的 myphpadmin 一起運行。 我試圖在 myphpadmin 中插入這段代碼：

ALTER USER 'root'@'localhost' IDENTIFIED WITH mysql_native_password BY '';

但是，如果我嘗試使用它，它會在 phpmyadmin 內給我一個錯誤：

在開始新的 ALTER 操作之前缺少“,”！

第二個說明：

未知的 ALTER 操作（附近）

當我想在 phpmyadmin 中使用或執行此命令時，我需要做些什么特別的事情嗎？ 因為 ALTER 查詢的編寫方式不允許我執行它..

節點（快遞）代碼：

var mysql = require("mysql");
var express = require("express");
var session = require("express-session");
var app = express();
var cors = require("cors");

var bodyParser = require("body-parser");
app.use(bodyParser.json({ limit: "50mb" }));
app.use(bodyParser.urlencoded({ limit: "50mb", extended: true }));

app.use(
  session({
    secret: "ssshhhhh",
    saveUninitialized: true, // (default: true)
    resave: true
  })
);

app.use(cors({ origin: ["http://localhost:4200"], credentials: true }));

var con = mysql.createConnection({
  host: "localhost",
  // host: "127.0.0.1:3307",
  user: "root",
  password: "",
  database: "fitness_app"
});

con.connect(err => {
  if (err) throw err;
  console.log("Database connected -> ");
});

var server = app.listen(8090, () => {
  var host = "localhost";
  var port = server.address().port;
  console.log("App listening at http://%s:%s", host, port);
});

在 MYSQL Workbench 中執行以下查詢

ALTER USER 'root'@'localhost' IDENTIFIED WITH mysql_native_password BY 'password';

其中 root 作為您的用戶 localhost 作為您的 URL 和密碼作為您的密碼

然后運行此查詢以刷新權限：

刷新特權；

完成后嘗試使用節點連接。

如果這不起作用，請嘗試不使用 @'localhost' 部分。
