我正在尝试将我的Laravel5.5升级到5.6.我已经按照Laravel网站上的说明进行操作，但是我得到了此错误：
Your requirements could not be resolved to an installable set of packages.
Problem 1
- The requested package laravel/framework 5.6.* is satisfiable by laravel/framework[5.6.x-dev] but these conflict with your requirements or minimum-stability.
因此，我更改了composer.json文件并添加了 2 行：**"minimum-stability": "dev", "prefer-stable": true,**基于此 laracast 讨论的第一个答案。
一切似乎都很好，直到我收到另一个错误：

In trustedproxy.php line 66:
Undefined class constant 'HEADER_CLIENT_IP'
Script @php artisan package:discover handling the post-autoload-dump event returned with error code 1
第 66 行的问题是Illuminate\Http\Request：：HEADER_CLIENT_IP => 'X_FORWARDED_FOR'，。 我已经在stackoverflow上搜索了其他帖子，但仍然没有运气。我尝试的最后一件事是作曲家自我更新和作曲家全局更新，这在后作曲家转储自动加载无法识别命令中提到
另外，我无法删除"最小稳定性"："dev"，"prefer-stable"：true，因为如果我这样做，那么我将收到以下错误：
- Installation request for laravel/framework 5.6.* -> satisfiable by laravel/framework[5.6.x-dev].
- Removal request for laravel/framework == 5.6.9999999.9999999-dev
我分别附加了我的 composer.json 文件和受信任代理.php。任何帮助将不胜感激。

谢谢
我这样做了，它工作得很好。
1. 作曲家.json：
从：
"require": {
"php": ">=7.0.0",
"fideloper/proxy": "~3.3",
"laravel/framework": "5.5.*",
"laravel/tinker": "~1.0"
},
自：
"require": {
"php": ">=7.1.3",
"fideloper/proxy": "~4.0",
"laravel/framework": "5.6.*",
"laravel/tinker": "~1.0"
},
2. 将 app\Http\Middleware\TrustedProxies.php 文件替换为以下内容：
<?php
namespace AppHttpMiddleware;
use IlluminateHttpRequest;
use FideloperProxyTrustProxies as Middleware;
class TrustProxies extends Middleware
{
/**
* The trusted proxies for this application.
*
* @var array
*/
protected $proxies;
/**
* The headers that should be used to detect proxies.
*
* @var string
*/
protected $headers = Request::HEADER_X_FORWARDED_ALL;
}
3. 作曲家更新
Laravel 的请求对象扩展了 Symfony 的请求对象。Laravel5.5依赖于Symfony 3，它有这个常数。Laravel5.6依赖于Symfony 4，它没有这个常数。
根据您的受信任代理配置，您似乎正在使用 Laravel "外部"的受信任代理包。Laravel在5.5的框架中引入了可信代理包，并创建了一个专用的AppHttpMiddlewareTrustProxies中间件供您使用。
我建议改用中间件并按照Laravel文档中的说明对其进行配置。这将有助于防止将来出现此类兼容性问题。
要进行切换：
-
在
app/Http/Kernel.php中，如果FideloperProxyTrustProxies::class位于$middleware数组中，请将其删除。如果AppHttpMiddlewareTrustProxies::class不在$middleware数组中，请添加它。 -
打开您的
app/Http/Middleware/TrustProxies.php文件并使用您的代理更新它。 -
删除
config/trustedproxy.php文件。 -
在
config/app.php中从providers数组中删除FideloperProxyTrustedProxyServiceProvider::class。 -
更新您的 composer.json 文件以使用"fideloper/proxy"："~4.0"。运行
composer update fideloper/proxy以更新包。
我已经从 5.5 更新到 5.6
作曲家.json
"minimum-stability":"dev",
"prefer-stable": true,
这将安装最新的Laravel软件包，然后TrustedProxies将出现问题。
安装Laravel 5.6的最新代理版本。
请在 Laravel 5.6 中使用标签 4.0+：
composer require fideloper/proxy:~4.0
更多详情
首先安装Laravel 5.6我也遇到了这个错误。 只需按照以下几个步骤即可修复它：
- 确保您的文件
composer.json要求具有：
"要求"：{ "php"： "^7.1.3"， "fideloper/proxy"： "^4.0"， }，
- 然后尝试
composer update以确保您的作曲家是最新的 - 最后运行：
composer require fideloper/proxy:~4.0 - 做！
对于尝试直接从 laravel 5.5 升级到 5.7 并遇到此问题的任何人，请从app->config->trustedproxy.php中删除受信任的代理.php文件。 希望对某人有所帮助。
只需要在 composer.json 文件中更改 fideloper/proxy ：-
您的作曲家.json文件现在：-
"fideloper/proxy": "~3.3",
将其更改为^4.0，如下所示：-
"fideloper/proxy": "^4.0",
之后，您需要运行更新编辑器，仅此而已。
composer update
您的问题来自您对库 TrustedProxy 的使用。
它使用Symfony的HEADER_CLIENT_IP常量，该常量在Symfony 3.3中被弃用，并在Symfony 4.0中完全删除。
由于Laravel 5.6已经更新为使用Symfony 4组件，这将不再起作用。
解决这个问题的方法是按照patricus的建议去做，并使用Laravel的TrustProxies中间件。
我做了以下事情，让我的项目在 Laravel 5.6-dev 上运行：
- 跟着什么帕特里库斯 建议
- 将fideloper/proxy更改为"~4.0"，并在我的composer.json文件的末尾添加了
"minimum-stability": "dev", "prefer-stable": true。
将 app\Http\Middleware\TrustedProxies.php替换为：
<?php
namespace AppHttpMiddleware;
use IlluminateHttpRequest;
use FideloperProxyTrustProxies as Middleware;
class TrustProxies extends Middleware
{
protected $proxies;
protected $headers = Request::HEADER_X_FORWARDED_ALL;
}
将 config\trustedproxy.php替换为：
<?php
return [
'proxies' => null,
'headers' => IlluminateHttpRequest::HEADER_X_FORWARDED_ALL,
];
由于某种原因，这里的建议都对我不起作用。 我正在使用快速管理面板和可能与之相关的各种依赖项。
最终奏效的是删除 laravel/dusk，然后自行更新为"fideloper/proxy": "~4.0",。 然后将 laravel/framework 更新到 5.6，然后重新安装 dusk。
我不需要：
"minimum-stability":"dev",
"prefer-stable": true,
也许最近的更新已修复。
面临同样的问题，并获得了许多指南来解决此问题。不幸的是，这些都不起作用，我也没有。实际上，解决此问题不需要解决其他步骤或任务。
只需按照 https://laravel.com/docs/5.6/upgrade 年的官方升级指南进行操作，然后删除位于config/trustedproxy.php的trustedproxy配置文件
在Laravel 5.7中遇到了同样的问题。您可以在.env中添加TELESCOPE_ENABLED=false或.env.dusk.local：来源
