mysql - 将 MySQL 与 WebStorm 结合使用不起作用

Question

我有一台 Mac 电脑。我已经成功安装MySQL了。我知道这一点是因为我可以从终端使用 mysql。我什至运行查询，它工作得很好。

我正在尝试使用 WebStorm 学习 Node.js。因此，在 WebStorm 中，我使用 package.json

创建项目

{
  "dependencies":{
    "mysql":"~2.0.0"
  }
}

然后我运行npm install来安装mysql模块。我运行以下代码，该代码不断记录未定义的结果。知道缺少什么吗？

'use strict';

var mysql = require('mysql');
var connection = mysql.createConnection({
    host:'localhost',
    user:'root',
    password:'myPassword'
});

connection.query(
    'SELECT "foo" as first_field, "bar" as second_field',
    function(err,results,fields){
        console.log(results);
        connection.end();
    }
);

当我记录错误时，我得到以下跟踪:

我认为您的问题与 WebStorm 无关。您登录 MySQL 的凭据似乎有误。

您是否尝试过使用命令行使用您的凭据登录？它有效还是您的登录也被拒绝？也许 root 登录被禁止。

如果可以进行 CLI 登录，也许以下答案之一会对您有所帮助:
