将Laravel从5.5升级到5.6时出错

Question

我正在尝试将我的Laravel5.5应用程序升级到Laravel5.6。为此，我一直在跟踪升级指南。

composer.json

{
    "name": "laravel/laravel",
    "description": "The Laravel Framework.",
    "keywords": ["framework", "laravel"],
    "license": "MIT",
    "type": "project",
    "require": {
        "php": ">=7.1.3",
        "encore/laravel-admin": "1.5.*",
        "fideloper/proxy": "~4.0",
        "intervention/image": "^2.4",
        "laravel/framework": "5.6.*",
        "laravel/passport": "^5.0",
        "laravel/tinker": "~1.0",
        "nesbot/carbon": "^1.22",
        "sebdesign/laravel-state-machine": "^1.2"
    },
    "require-dev": {
        "fzaninotto/faker": "~1.4",
        "laravel/homestead": "^5.1",
        "mockery/mockery": "0.9.*",
        "phpunit/phpunit": "~7.0",
        "filp/whoops": "~2.0"
    },
}

但是，当我使用composer update时，我会得到以下错误：

problem 1
    - Conclusion: don't install laravel/framework v5.6.17
    - Conclusion: don't install laravel/framework v5.6.16

我试着删除vendor目录并重新运行composer update，但仍然无法工作。

我该怎么解决这个问题？

Answer 1

您需要将laravel/homestead升级到6.x或7.x行。5.x不支持Laravel 5.6所要求的Symfony 4。

"require-dev": {
    "laravel/homestead": "^6.6",
    ...
},

对于这样的问题，你应该试着阅读这些30k字符--你所需要的就是：

• laravel/宅基地v5.1.0需要symfony/process ~2.3区~3.0/.
• laravel/FrameworkV5.6.0需要symfony/process ~4.0 /./

Answer 2

看起来有些依赖项没有更新，或者不支持Laravel5.6。

按照本视频指南从laravel 5.5至5.6升级
