将 laravel 项目从 5.3 升级到 5.8

Question

我正在做一个项目，我正在尝试将我当前的 php 版本从 5.6 升级到 7.3，将 laravel 5.3 升级到 5.8，将 backpack 0.7 升级到最终版本，然后运行 composer update 但我得到的只是以下错误：

    - Installation request for laravelcollective/html 5.3.1 -> satisfiable by laravelcollective/html[v5.3.1].

这是 composer.json 要求

"require": {
        "php": ">=7.3.1",
        "laravel/framework": "5.3.*",
        "laravelcollective/html": "5.3.1",
        "backpack/base": "^0.7.14",
        "backpack/crud": "^3.1",
        "backpack/permissionmanager": "^2.1",
        "backpack/langfilemanager": "^1.0",
        "mikehaertl/phpwkhtmltopdf": "2.2.1",
        "artisaninweb/laravel-soap": "0.3.0.7",

升级Laravel and/or背包时，建议不要跳版本。我从未尝试过从 L5.3 直接跳到 5.8，但我不希望它起作用。

Laravel 和 Backpack 都发布了每个版本的升级指南。那是因为升级过程不仅仅是更改 composer.json 文件中的数字。它还涉及您需要手动执行的一些步骤。否则您的应用程序将无法运行。我知道这很不方便，但这是升级您可以自定义的代码的唯一可能方法。

我的推荐：

您可以使用 Laravel Shift 自动完成大部分 Laravel 升级。这是一项向您的 Github/Gitlab/Bitbucket 存储库发出拉取请求的付费服务。恐怕你不能自动升级背包，但在大多数情况下，步骤会很清楚，变化也很小。

希望对您有所帮助。
