我在laravel scout中遇到了这样的错误:您的需求无法解决为一组可安装的软件包

Question

安装Laravel Scout:时出现此错误

问题1-laravel/scout[v9.1.0，…，9.x-dev]需要照明/bus ^8.0->找到了illuminat/bus[v8.0.0，…，8.x-dev]，但这些文件没有加载，可能是因为它与另一个需求冲突。-根composer.json需要laravel/scout ^9.1->可由laravel/scout满足[v9.1.0，9.x-dev].

使用选项--连同所有依赖项(-W(，可以对当前锁定到特定版本的包进行升级、降级和删除。

这是我的composer.json文件：

Answer 1

在您的作曲家中，"laravel/framework": "^7.29",等同于>=7.29 <8.0.0，但您需要illuminate/bus[v8.0.0, ..., 8.x-dev]，它是laravel/framework >=8.0.0的一部分

因此，您无法安装laravel scount版本>=9.0

尝试使用以下命令安装与laravel 7.x兼容的8.6.1版本：

composer require "laravel/scout:^8.6.1"

Answer 2

您应该只安装ext-xml

sudo apt-get install php-xml
sudo apt-get install php-curl
