php - Composer update/create-project/install - HTTP 请求失败

Question

最近我了解了 Laravel 4.2。然后我切换到 Laravel 5。我一直使用 composer 添加其他依赖项和东西，我一点问题都没有。

上周四我使用 composer create-project laravel/laravel dir_name --prefer-dist 创建了一个新项目。一切顺利。

但是从周五开始，我什么也做不了。每次我尝试创建新项目、更新依赖项或做任何事情时，都会等待很长时间(几乎就像卡住一样)，然后出现错误。它们通常是关于 HTTP 请求失败 或 packagist.org 的问题。

在工作中我没有任何问题。我 friend 也不会。它在我的电脑上工作，然后突然停止了。请帮忙。

我的 Composer 是最新的:

C:\xampp\htdocs\dir_name>composer self-update
You are already using composer version 9fb2d4f2d642a0749decb41bc2fe4be2bf8bef7a.

C:\xampp\htdocs\dir_name>

那是composer update -vvv:

在家里，我在路由器后面，但我不知道有代理。我不知道发生了什么变化。从 composer.json 开始 - 即使使用来自 laravel/laravel 的全新干净 .json，更新也无法正常启动。

感谢任何帮助。您知道为什么会发生这种情况或如何解决这个问题吗？

我已经在这里尝试过了，我已经用 composer 克隆了一个新的 laravel5 项目。

composer create-project laravel/laravel --prefer-dist

就像您提到的日志一样，您无法打开路由依赖项，因为给定的 json 文件不存在并且您收到 404 错误。所以我认为您的任何依赖项都不正确。

Routing JSON

我完全没有问题，可以克隆一个包含所有依赖项的新项目。它运作良好。是否有可能您在 composer.json 中为某些函数添加了一些第 3 方依赖项并且项目具有错误或不再存在的依赖项？

我应该尝试的是首先清理所有缓存。

composer clear-cache

为了确保一切正常，您可以运行诊断程序。

composer diagnose

接下来尝试检查所有依赖项。这是一个新鲜的 composer.json。

{
    "name": "laravel/laravel",
    "description": "The Laravel Framework.",
    "keywords": ["framework", "laravel"],
    "license": "MIT",
    "type": "project",
    "require": {
        "php": ">=5.5.9",
        "laravel/framework": "5.1.*"
    },
    "require-dev": {
        "fzaninotto/faker": "~1.4",
        "mockery/mockery": "0.9.*",
        "phpunit/phpunit": "~4.0",
        "phpspec/phpspec": "~2.1"
    },
    "autoload": {
        "classmap": [
            "database"
        ],
        "psr-4": {
            "App\\": "app/"
        }
    },
    "autoload-dev": {
        "classmap": [
            "tests/TestCase.php"
        ]
    },
    "scripts": {
        "post-install-cmd": [
            "php artisan clear-compiled",
            "php artisan optimize"
        ],
        "post-update-cmd": [
            "php artisan clear-compiled",
            "php artisan optimize"
        ],
        "post-root-package-install": [
            "php -r \"copy('.env.example', '.env');\""
        ],
        "post-create-project-cmd": [
            "php artisan key:generate"
        ]
    },
    "config": {
        "preferred-install": "dist"
    },
    "minimum-stability": "dev",
    "prefer-stable": true
}

有时我会遇到这个问题，如果我尝试克隆某些东西，服务响应需要很长时间，但在您的情况下，它会很长。

我建议启用 openssl 扩展。您无法建立 SSL 连接。

Checking http connectivity: FAIL
[Composer\Downloader\TransportException] The "https://packagist.org/packages.json" file could not be
 downloaded: SSL: Handshake timed out

在您的 phpinfo() 中检查，您可以使用干净的文件进行另一次检查:

<?php
echo file_get_contents("https://packagist.org/packages.json");

为避免您的命令行使用其他 php 解释器或未启用 openssl 的其他版本，您可以直接从命令行对其进行测试。

#php -r 'echo file_get_contents("https://packagist.org/packages.json");'

最后一个是将 openssl 更新到最新版本，如果您没有最新版本，则更新 XAMPP。
