Question

我对编程和Web开发还很陌生。现在，我试图使用node.js将我的网站连接到Postgres数据库。为此，我在节点上安装了一个pg库，并使用以下代码创建了一个名为test.js的文件：

const {Client} = require('pg');
const client = new Client({
    user: "postgres",
    password: "postgres",
    host: "DESKTOP-SHUAAH5",
    database: "mainbase"
})


client.connect()
.then(() =>  console.log("Connected succsessfully"))
.catch(e => console.log(e))
.finally(() => client.end   ())

当我尝试通过npm测试运行它时，我收到以下错误：

PS C:\webtest> npm test
> webtest@1.0.0 test C:\webtest
> node test.js

}

当我尝试使用调试器在VS代码中运行它时，出现以下错误：

internal/modules/cjs/loader.js:968
  throw err;
  ^

Error: Cannot find module 'c:/Users/������/AppData/Local/Programs/Microsoft VS Code/resources/app/extensions/ms-vscode.js-debug/src/bootloader.bundle.js'
Require stack:

    at internal/main/run_main_module.js:7:1 {
  code: 'MODULE_NOT_FOUND',
  requireStack: [ 'internal/preload' ]
}

所以我想问题是字符编码。我该如何解决？我必须安装用于Node / VS代码的任何软件包吗？我的母语是俄语，所以我的用户名也是用俄语编写的。不胜感激。

很抱歉，这是一个漫长而又糟糕的问题，但我确实停留在这一点上
