laravel9.19安装失败

[WangQuanTang]

• Laravel Version: 9.19
• PHP Version: 8.0.9
• Dcat Admin Version: 2.*

Description:

安装提示：

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

  Problem 1
    - Root composer.json requires dcat/laravel-admin 2.*, found dcat/laravel-admin[2.0.0-beta, 2.0.1-beta, 2.0.2-beta, 2.0.3-beta, 2.0.4-beta, 2.0.5-beta, 2.0.6-beta, 2.0.7-beta, 2.0.8-beta, 2.0.9-beta, 2.0.10-beta, 2.0.11-beta, 2.0.12-beta, 2.0.13-beta, 2.0.14-beta, 2.0.15-beta, 2.0.16-beta, 2.0.17-beta, 2.0.18-beta, 2.0.19-beta, 2.0.20-beta, 2.0.21-beta, 2.0.22-beta, 2.0.23-beta, 2.0.24-beta, 2.0.x-dev, 2.1.0-beta, 2.1.1-beta, 2.1.2-beta, 2.1.3-beta, 2.1.4-beta, 2.1.5-beta, 2.1.6-beta, 2.1.7-beta, 2.2.0-beta, 2.2.1-beta, 2.2.2-beta] but it does not match your minimum-stability.

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

根据这篇文章： laravel 8.32无法安装dcat-admin 2.x的方法，去掉"prefer-stable": true后依旧提示错误。 删除composer.lock后运行composer clearcache清除缓存，再composer update后生成composer.lock再安装依旧提示上述错误。 尝试指定版本：

composer require dcat/laravel-admin:"2.2.2-beta*"

安装成功，但是在config/app.php中修改语言配置为：local => zh_CN后语言配置不生效。 最后尝试更换源也是一样报错。

总结:

问题1：按照文档流程安装提示Your requirements could not be resolved to an installable set of packages。 问题2：指定特定版本后，语言配置不生效。

composer.json里把minimum-stability的值改为dev
