我正在尝试导入池，但遇到错误。
下面是抛出的错误：

import { Pool } from "pg";
         ^^^^
SyntaxError: Named export 'Pool' not found. The requested module 'pg' is a CommonJS module, which may not support all module.exports as named exports.

这是我的代码：

import { Pool } from "pg";

dotenv.config();

const databaseConfig = { connectionString: process.env.DATABASE_URL };
const pool = new Pool(databaseConfig);

export default pool;
