Laravel 8安装yajra/laravel-datatables-oracle依赖冲突求助

操作与错误信息 #

执行以下安装命令：

composer require yajra/laravel-datatables-oracle

出现依赖解析失败错误：

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

Problem 1
- yajra/laravel-datatables[dev-master, v9.0.0] require yajra/laravel-datatables-oracle 10.* -> satisfiable by yajra/laravel-datatables-oracle[v10.0.0, ..., 10.x-dev (alias of dev-master)].
- yajra/laravel-datatables-oracle 10.x-dev is an alias of yajra/laravel-datatables-oracle dev-master and thus requires it to be installed too.
- yajra/laravel-datatables-oracle[dev-master, v10.0.0, ..., v10.1.2] require illuminate/database ^9 -> found illuminate/database[v9.0.0-beta.1, ..., 9.x-dev] but these were not loaded, likely because it conflicts with another require.
- yajra/laravel-datatables 9.0.x-dev is an alias of yajra/laravel-datatables dev-master and thus requires it to be installed too.
- Root composer.json requires yajra/laravel-datatables ^9.0 -> satisfiable by yajra/laravel-datatables[v9.0.0, 9.0.x-dev (alias of dev-master)].

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

注：composer.json中仅指定了最低依赖要求。

解决方案 #

问题核心是默认安装的yajra/laravel-datatables-oracle 10.x版本要求Laravel 9+，而当前项目使用Laravel 8.x，需指定兼容Laravel 8的9.x版本执行安装：

composer require yajra/laravel-datatables-oracle:^9.0
