如何解决问题？

Answer 1

我通过更改SSLCommerz的软件包解决了问题。我使用了SSLCommerz-LTS软件包，然后构造函数不显示错误。

npm i sslcommerz-lts

const express = require('express')
const app = express()

const SSLCommerzPayment = require('sslcommerz-lts')
const store_id = '<your_store_id>'
const store_passwd = '<your_store_password>'
const is_live = false //true for live, false for sandbox

const port = 3030

//sslcommerz init
app.get('/create-session', (req, res) => {
    const data = {
        total_amount: 100,
        currency: 'BDT',
        tran_id: 'REF123', // use unique tran_id for each api call
        success_url: 'http://localhost:3030/success',
        fail_url: 'http://localhost:3030/fail',
        cancel_url: 'http://localhost:3030/cancel',            
        shipping_method: 'Courier',
        product_name: 'Computer.',
        product_category: 'Electronic',
        product_profile: 'general',
        cus_name: 'Customer Name',
        cus_email: '[email protected]',
        cus_add1: 'Dhaka',
        cus_add2: 'Dhaka',
        cus_city: 'Dhaka',
        cus_state: 'Dhaka',
        cus_postcode: '1000',
        cus_country: 'Bangladesh',
        cus_phone: '01711111111',
        cus_fax: '01711111111',
        ship_name: 'Customer Name',
        ship_add1: 'Dhaka',
        ship_add2: 'Dhaka',
        ship_city: 'Dhaka',
        ship_state: 'Dhaka',
        ship_postcode: 1000,
        ship_country: 'Bangladesh',
    };
    const sslcz = new SSLCommerzPayment(store_id, store_passwd, is_live)
    sslcz.init(data).then(apiResponse => {
        // Redirect the user to payment gateway
        let GatewayPageURL = apiResponse.GatewayPageURL
        res.redirect(GatewayPageURL)
        console.log('Redirecting to: ', GatewayPageURL)
    });
})

app.listen(port, () => {
    console.log(`Example app listening at http://localhost:${port}`)
})

然后我在命令提示符“ node index.js'中运行
我得到了输出。

Answer 2

更改

import {SSLPayment}

为

import * as SSLCommerzPayment from 'sslcommerz-lts';

，它将起作用
