我正在尝试将 laravel/sail 安装到一个现有项目中，该项目之前似乎没有安装过。我相信这个项目通常是在 vagrant 上运行的。
我正在尝试使用 Laravel Sail 让它在 WSL2 上运行。我也不完全确定这是否是我的最佳方法。
我的理解是，我可以使用 sail 通过 docker 运行项目，只需最少的设置和配置。
当我尝试通过 composer 安装 sail 时，我似乎遇到了错误。这些是我遵循的说明:https://laravel.com/docs/9.x/sail#installing-sail-into-existing-applications
这是错误:
$ composer require laravel/sail --dev
PHP Warning: PHP Startup: Unable to load dynamic library 'pdo_mysql' (tried: /usr/lib/php/20190902/pdo_mysql (/usr/lib/php/20190902/pdo_mysql: cannot open shared object file: No such file or directory), /usr/lib/php/20190902/pdo_mysql.so (/usr/lib/php/20190902/pdo_mysql.so: undefined symbol: mysqlnd_allocator)) in Unknown on line 0
Using version ^1.13 for laravel/sail
./composer.json has been updated
Running composer update laravel/sail
Loading composer repositories with package information
Updating dependencies
Your requirements could not be resolved to an installable set of packages.
Problem 1
- Root composer.json requires laravel/sail ^1.13 -> satisfiable by laravel/sail[v1.13.0, ..., 1.x-dev].
- laravel/sail[v1.13.0, ..., 1.x-dev] require illuminate/contracts ^8.0|^9.0 -> found illuminate/contracts[v8.0.0, ..., 8.x-dev, v9.0.0-beta.1, ..., 9.x-dev] but these were not loaded, likely because it conflicts with another require.
You can also try re-running composer require with an explicit version constraint, e.g. "composer require laravel/sail:*" to figure out if any version is installable, or "composer require laravel/sail:^2.1" if you know which you need.
Installation failed, reverting ./composer.json and ./composer.lock to their original content.
我不完全确定如何解释这一点，但看起来正在尝试安装的版本与另一个必需的包不兼容。

最佳答案
不幸的是，您将无法使用 laravel/sail 基于您当前的 Laravel 框架版本。
说明:
laravel/sail="1.13" 需要 illuminate/contracts : ^8.0|^9.0`
现在，问自己一个问题，哪些包依赖于illuminate/contracts在 Laravel v6 中？
命令:composer depends illuminate/contracts
输出:
Info from https://repo.packagist.org: #StandWithUkraine
fideloper/proxy 4.4.1 requires illuminate/contracts (^5.0|^6.0|^7.0|^8.0|^9.0)
laravel/framework v6.18.43 replaces illuminate/contracts (self.version)
laravel/tinker v1.0.10 requires illuminate/contracts (~5.1|^6.0)
根据上面的输出，您有点意识到所有依赖项之间的通用 illuminate/contracts 版本是^6.0 .
考虑到这一点，您通常需要安装 laravel/sail需要 illuminate/contracts 的版本: ^6.0`
不幸的是，这不可能。之所以如此，是因为即使是第一个 laravel/sail版本 ( dev-develop ) 需要 illuminate/contracts : ^8.0|^9.0|^10.0.
现在，最合理的选择是首先升级项目中依赖于illuminate/contracts 的包。在上面的输出 中的所有 3 个包中，有 Laravel 框架。可悲的是，第一个满足 illuminate/contracts: ^8.0|^9.0 的框架版本要求是 laravel/framework v8.0.0 。如果这是你会考虑的事情，那么你可能想看看 Laravel 8 upgrade guide .
可能的解决方案:
考虑到 Laravel Sail只是一个工具，为您提供使用 PHP、MySQL 和 Redis 构建 Laravel 应用程序的起点，而无需先前的 Docker 经验，还有其他工具可以以类似的方式完成工作。
我可能建议的一个工具是 Laradock .
如果您有足够的 Docker 经验，您甚至可以借助来自 Docker Hub 的现成的公共(public)官方 Docker 图像，从头开始部署您自己的 Docker 设置。 .
