PayPal Checkout：未找到LiveEnvironment类

Question

[我正在建立一个具有PayPal集成的网站，我正在看教程...在沙盒中，一切正常，但是在Live中，它无法正常工作...

关键是，付款执行得很好，但是随后我尝试检索订单信息，我得到了：

<br />
<b>Fatal error</b>:  Uncaught Error: Class 'PayPalCheckoutSdk\Core\LiveEnvironment' not found in /api/sources/Classes/PaypalClient.php:25
Stack trace:
#0 /api/sources/Classes/PaypalClient.php(16): PayPalClient::environment()
#1 /api/sources/Controllers/PaymentController.php(116): PayPalClient::client()

#7 /api/autoloader.php(7): require_once('/home/soinsdesz...')
#8 /api/public/index.php in <b>/api/sources/Classes/PaypalClient.php</b> on line <b>25</b><br />

这是我的PaypalClient.php类：

<?php

use PayPalCheckoutSdk\Core\PayPalHttpClient;
use PayPalCheckoutSdk\Core\SandboxEnvironment;
use PayPalCheckoutSdk\Core\LiveEnvironment;

class PayPalClient
{
    /**
     * Returns PayPal HTTP client instance with environment that has access
     * credentials context. Use this instance to invoke PayPal APIs, provided the
     * credentials have access.
     */
    public static function client()
    {
        return new PayPalHttpClient(self::environment());
    }

    /**
     * Set up and return PayPal PHP SDK environment with PayPal access credentials.
     * This sample uses SandboxEnvironment. In production, use LiveEnvironment.
     */
    public static function environment()
    {
        return (ENV === "prod") ? new LiveEnvironment(PAYPAL_CLIENT_ID, PAYPAL_PRIVATE_KEY) : new SandboxEnvironment(PAYPAL_CLIENT_ID, PAYPAL_PRIVATE_KEY);
    }
}

有人可以帮我吗？

确定，我找到了解决方法，所以...

在本教程中说：“改为使用LiveEnvironment” ...它是WRONG（感谢PayPal ！！）正确的类名是ProductionEnvironment！

PayPal可以修改他的教程吗：https://developer.paypal.com/docs/checkout/reference/server-integration/setup-sdk/
