【问题描述】：

我在安装 Laravel Jetstream 时遇到此错误：

Your requirements could not be resolved to an installable set of packages.

  Problem 1
    - laravel/jetstream[v2.3.0, ..., 2.x-dev] require league/commonmark ^1.3 -> found league/commonmark[1.3.0, ..., 1.6.x-dev] but the package is fixed to 2.0.0 (lock file version) by a partial update and that version does not match. Make sure you list it as an argument for the update command.
    - Root composer.json requires laravel/jetstream ^2.3 -> satisfiable by laravel/jetstream[v2.3.0, ..., 2.x-dev].

Use the option --with-all-dependencies (-W) to allow upgrades, downgrades and removals for packages currently locked to specific versions.

Installation failed, reverting ./composer.json and ./composer.lock to their original content.

这是一个全新安装的Laravel Framework 8.51.0

【解决方案1】：

我尝试安装新的 laravel（特定的 laravel 项目像这样）：

composer create-project --prefer-dist laravel/laravel:^8.0 olshop-larafel

然后进入这个项目

cd olshop-larafel

并安装 laravel/jetstream：

composer require laravel/jetstream

一切正常。您是否尝试过安装 laravel 8.0 特定版本？

更新

在运行composer require laravel/jetstream 之前删除composer.lock。

在composer.json 的require 中手动添加"league/commonmark": "^1.3"。然后最后安装jetstream。

阅读讨论here。

【讨论】：

composer.lock 是一个自动生成的文件，可能/将被覆盖
猜这不是一个合适的解决方案。你有什么建议吗？谢谢。
另外，在执行php artisan jetstream:install livewire 时仍然出现错误。所以它真的没有帮助。
