你可以回答我吗？我使用最新版本的Laravel，我想在我的项目中添加PayPal服务 . 我想在Laravel上安装一些软件包，并将这两行添加到composer.json中
"guzzlehttp/guzzle": "~5.2",
"paypal/rest-api-sdk-php": "*"
我的composer.json文件
{
"name": "laravel/laravel",
"description": "The Laravel Framework.",
"keywords": ["framework", "laravel"],
"license": "MIT",
"type": "project",
"require": {
"php": ">=7.0.0",
"fideloper/proxy": "~3.3",

},
"require-dev": {

},
"autoload": {
"classmap": [

"database/factories"
],
"psr-4": {

}
},
"autoload-dev": {

}
},
"extra": {

"scripts": {
"post-root-package-install": [
"/usr/local/bin/php -r \"file_exists('.env') || copy('.env.example', '.env');\""
],
"post-create-project-cmd": [
"/usr/local/bin/php artisan key:generate"
],
"post-autoload-dump": [
"Illuminate\\Foundation\\ComposerScripts::postAutoloadDump",
"/usr/local/bin/php artisan package:discover"
]
},
"config": {
"preferred-install": "dist",
"sort-packages": true,
"optimize-autoloader": true,
"cache-dir": "/home/iamdevco/public_html/norrisms/designer/cache"
},
"guzzlehttp/guzzle": "~5.2",
"paypal/rest-api-sdk-php": "*"
}
但下载包后我收到此错误
$ composer update
使用包信息加载composer存储库更新依赖项（包括require-dev）无需安装或更新生成优化的自动加载文件
Illuminate \ Foundation \ ComposerScripts :: postAutoloadDump / usr / local / bin / php artisan package：discover系统找不到指定的路径 . 脚本/ usr / local / bin / php artisan包：发现处理返回的post-autoload-dump事件，错误代码为1

安装完所有包后运行
packages
composer require guzzlehttp/guzzle-services
composer require paypal/rest-api-sdk-php
composer dumpautoload
而不是手动编写
composer.json，尝试使用特定命令安装和添加它们 . 像这样 .这样，你就可以避免任何拼写错误，
composer.json文件将尽可能保持纯正 .试试这个
composer require paypal/rest-api-sdk-php参考：https://packagist.org/packages/paypal/rest-api-sdk-php
编辑：删除composer.json和guzzle上的paypal / rest-api-sdk-php然后尝试这个
