Question

我正在一个项目上，我正在尝试将当前版本的php 5.6升级到7.3，将laravel 5.3升级到5.8，将背包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的要求

"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",

在升级Laravel和/或背包时，建议您不要跳版本。我从未尝试过直接从L5.3跳到5.8，但我不希望它能起作用。

Laravel和Backpack均发布了每个版本的升级指南。那是因为升级过程不只是更改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。

我的建议：

您可以使用Laravel Shift自动执行大部分Laravel升级。这是一项付费服务，可向您的Github / Gitlab / Bitbucket存储库发出拉取请求。恐怕您无法自动执行背包升级，但是在大多数情况下，这些步骤很清楚，而且更改很小。

希望有帮助。
