有没有办法从 pg 导入 { pool }

Question

我正在尝试导入 Pool，但出现错误。

这是抛出的错误：

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

您应该使用默认导出：

import pg from "pg";
const { Pool } = pg;

dotenv.config();

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

export default pool;
