Laravel Update / install composer package

Question

你能回答我吗？我使用最新版本的Laravel，我想将PayPal服务添加到我的项目中。我想安装一些软件包到Laravel，并将这2行添加到Composer.json

"guzzlehttp/guzzle": "~5.2",
"paypal/rest-api-sdk-php": "*"

我的composer.json文件

    },
    "guzzlehttp/guzzle": "~5.2",
"paypal/rest-api-sdk-php": "*"
}

$ composer update

Answer 1

安装所有包裹后

composer dumpautoload

软件包

1. composer require guzzlehttp/guzzle-services
2. composer require paypal/rest-api-sdk-php
3. composer dumpautoload

Answer 2

而不是手动编写composer.json，尝试使用特定命令安装并添加它们。这样。

composer require paypal/rest-api-sdk-php
composer require guzzlehttp/guzzle

这样，您将避免任何错别字，并且composer.json文件将尽可能纯净。

Answer 3

尝试此composer require paypal/rest-api-sdk-php

参考：https：//packagist.org/packages/paypal/rest-api-sdk-php

编辑：删除作曲家上的PayPal/REST-API-SDK-PHP。

composer require guzzlehttp/guzzle
