Laravel更新/安装作曲家软件包

Question

你可以回答我吗？ 我使用的是最新版本的Laravel，我想将PayPal服务添加到我的项目中。 我想将一些软件包安装到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

   {
    "name": "laravel/laravel",
    "description": "The Laravel Framework.",
    "keywords": ["framework", "laravel"],
    "license": "MIT",
    "type": "project",
    "require": {
        "php": ">=7.0.0",
        "fideloper/proxy": "~3.3",
        "laravel/framework": "5.5.*",
        "laravel/tinker": "~1.0"
    },
    "require-dev": {
        "filp/whoops": "~2.0",
        "fzaninotto/faker": "~1.4",
        "mockery/mockery": "0.9.*",
        "phpunit/phpunit": "~6.0"
    },
    "autoload": {
        "classmap": [
            "database/seeds",
            "database/factories"
        ],
        "psr-4": {
            "App\\": "app/"
        }
    },
    "autoload-dev": {
        "psr-4": {
            "Tests\\": "tests/"
        }
    },
    "extra": {
        "laravel": {
            "dont-discover": [
            ]
        }
    },
    "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": "*"
}

但是下载软件包后出现此错误

$ composer update

使用软件包信息加载composer存储库更新依赖关系（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软件包：discover系统找不到指定的路径。 脚本/ usr / local / bin / php artisan软件包：发现处理返回的错误代码为1的post-autoload-dump事件

Answer 1

安装所有程序包后运行

composer dumpautoload

包

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

Answer 2

与其手动编写composer.json ，不如尝试使用特定命令进行安装和添加。 像这样。

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文件将尽可能保持纯净。

Answer 3

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

composer require guzzlehttp/guzzle
