我正在尝试将我的Laravel 5.5升级到5.6.我已按照laravel网站上的说明操作，但我收到此错误：
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.
所以，我根据this laracast讨论的第一个答案更改了我的composer.json文件并添加了两行：**"minimum-stability": "dev", "prefer-stable": true,**。
在我收到另一个错误之前，一切似乎都运转正常：

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 =＆gt; ＆＃39; X_FORWARDED_FOR＆＃39;，即可。 我在stackoverflow上搜索了其他帖子，但仍然没有运气。我尝试过的最后一件事是作曲家自我更新和作曲家全局更新，在帖子composer dump-autoload not recognized command
上提到了此外，我无法删除＆＃34;最低稳定性＆＃34;：＆＃34; dev＆＃34;，＆＃34; prefer-stable＆＃34;：如果我这样做，那么我会得到以下错误：
- 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
我已经分别附加了我的composer.json文件和trustedproxy.php。任何帮助将受到高度赞赏。

"require": {
"php": ">=7.0.0",
"fideloper/proxy": "~3.3",
"laravel/framework": "5.5.*",

第3。作曲家更新
答案 1 :(得分：32)
Laravel的Request对象扩展了Symfony的Request对象。 Laravel 5.5依赖于Symfony 3，它具有该常量。 Laravel 5.6依赖于Symfony 4，它没有那个常量。
根据您的受信任代理配置，您似乎正在使用受信任的代理包＆＃34;外部＆＃34; Laravel。 Laravel在5.5中的框架内引入了可信代理包，并创建了一个专用的\App\Http\Middleware\TrustProxies中间件供您使用。
我建议转移使用中间件并按照Laravel documentation中的说明进行配置。这将有助于防止此类兼容性问题。
进行切换：
在app/Http/Kernel.php中，如果您\Fideloper\Proxy\TrustProxies::class数组中有$middleware，请将其删除。如果\App\Http\Middleware\TrustProxies::class数组中没有$middleware，请添加它。
打开您的app/Http/Middleware/TrustProxies.php文件并使用您的代理进行更新。
删除config/trustedproxy.php文件。
从Fideloper\Proxy\TrustedProxyServiceProvider::class中的providers数组中移除config/app.php。
更新您的composer.json文件以使用＆＃34; fideloper / proxy＆＃34;：＆＃34; ~4.0＆＃34;。运行composer update fideloper/proxy更新软件包。
答案 2 :(得分：8)
我已从5.5更新到5.6
composer.json
"minimum-stability":"dev",
"prefer-stable": true,
这将安装最新的Laravel软件包，然后TrustedProxies会出现问题。
为Laravel 5.6安装最新的代理版本。
请使用标签4.0+用于Laravel 5.6：
composer require fideloper/proxy:~4.0
答案 3 :(得分：4)
首先安装 Laravel 5.6 ，我也遇到了此错误。 只需按照以下几个步骤即可解决问题：
File file = new File(videoPathUri.getPath());
try {
FileInputStream inputStream = new FileInputStream(file.getAbsolutePath());
metadataRetriever.setDataSource(inputStream.getFD());
}catch(FileNotFoundException e){
Log.d("DEBUG", "FileNotFoundException", e);
}catch(IOException ea){
Log.d("DEBUG", "IOException", ea);
}
要求具有： "require": {
"php": "^7.1.3",
"fideloper/proxy": "^4.0",
},
composer.json以确保您的作曲家是最新的composer update 答案 4 :(得分：3)
对于任何尝试直接从laravel 5.5升级到5.7并也遇到此问题的人，请从app->config->trustedproxy.php中删除Trustedproxy.php文件。
希望能对某人有所帮助。
答案 5 :(得分：2)
您的问题来自您使用库TrustedProxy。
它使用Symfony的HEADER_CLIENT_IP常量已弃用与Symfony 3.3并在Symfony 4.0中完全删除。
由于Laravel 5.6已更新为使用Symfony 4组件，因此将不再有效。
解决问题的方法是 do what patricus suggested 并使用Laravel的TrustProxies中间件。
答案 6 :(得分：2)
我做了以下事情并让我的项目在Laravel 5.6-dev上运行：
"minimum-stability":
"dev", "prefer-stable": true。答案 7 :(得分：1)
面对同样的问题并获得了一些解决此问题的指导原则。不幸的是，没有人或我。实际上，没有额外的步骤或任务需要解决以解决此问题。
只需按照https://laravel.com/docs/5.6/upgrade中的官方升级指南进行操作，然后删除位于trustedproxy的{{1}}配置文件
答案 8 :(得分：1)
只需更改composer.json文件中的fideloper / proxy：-
您现在的composer.json文件：-
"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。
composer update
答案 9 :(得分：0)
由于某种原因，这里没有任何建议对我有效。我正在使用quickadmin面板和各种可能与它有关的依赖项。
最终有效的方法是删除laravel / dusk，然后自行更新为"fideloper/proxy": "~4.0",。然后将laravel / framework更新为5.6，然后重新安装黄昏。
我不需要：
"minimum-stability":"dev",
"prefer-stable": true,
最近的更新可能已经解决了这个问题。
答案 10 :(得分：0)
在Laravel 5.7中有同样的问题。您可以在cv2.imread()或TELESCOPE_ENABLED=false中添加.env：Source
