laravel - 安装laravel-scout-elastic版本时出错

Question

我想在laravel 5.7.11应用中使用elasticsearch并进行一些搜索，发现
插件laravel-scout-elastic(https://github.com/ErickTamayo/laravel-scout-elastic)
我先尝试了elasticsearch / elasticsearch和laravel-scout-elastic插件，最后显示了错误:

您能建议我安装哪些版本以及如何安装吗？我的意思是是否必须在控制台命令中设置packeges的版本？

请显示这些命令的格式...

# php -v
PHP 7.2.10-0ubuntu0.18.04.1 (cli) (built: Sep 13 2018 13:45:02) ( NTS )

谢谢!

您必须首先通过以下命令安装Scout:

composer require laravel/scout "5.0.x-dev"
