Php 从5.5 composer更新到laravel 5.6失败

我一直在遵循Laravel网站上提供的5.5->5.6版本的升级指南

当我运行composer安装时，一切似乎都正常，但当我运行composer更新时，一切都变得不稳定，这似乎是我应该关心的事情，我如何修复它

根据文件规定：

Laravel5.6需要PHP7.1.3或更高版本

尝试使用以下内容更改composer.json：

"require": {
    "php": ">=7.1.3",

如果有帮助，请告诉我

编辑

尝试更改配置：

"config": {
    "preferred-install": "dist",
    "sort-packages": true,
    "optimize-autoloader": true,
    "minimum-stability":"dev",
    "prefer-stable": true
}

并检查所有必需的插件是否支持最新版本的laravel。

它看起来像是

sofa/eloquence

5.5.1需要laravel 5.5，这阻止了您升级到laravel 5.6

看起来他们三天前发布了一个兼容Laravel 5.6的软件包；您可以编辑composer文件，将其版本更改为5.6，然后运行

composer update

    "sofa/eloquence": "^5.6",
    "sofa/eloquence-base":"^5.6",

看起来

sofa/elource

5.5.1需要Laravel 5.5，这会阻止您升级到Laravel 5.6
