我想安装 laravel/horizo​​n 但它给出错误 laravel v9

Question

我写作曲家要求 laravel/horizo​​n 作曲家，但它给出了这个错误：

您的要求无法解决为一组可安装的软件包。

问题 1 - 根 composer.json 需要 laravel/horizo​​n ^0.1.0 -> 可由 laravel/horizo​​n[v0.1.0] 满足。 - laravel/horizo​​n v0.1.0 需要照明/合同 ~5.4 -> 找到照明/合同 [v5.4.0, ..., 5.8.x-dev] 但这些没有加载，可能是因为它与另一个要求冲突。

您也可以尝试使用明确的版本约束重新运行 composer require，例如“composer require laravel/horizo​​n:*”来确定是否有任何版本是可安装的，或者“composer require laravel/horizo​​n:^2.1”如果你知道你是哪个需要。

安装失败，正在将 ./composer.json 和 ./composer.lock 还原为其原始内容。

my composer.json ：
