Yajra DataTable 未在 Laravel 5.7 上安装。*

Yajra DataTable Is Not Installing on Laravel 5.7.*

我在 Powershell 上使用此命令“composer require yajra/laravel-datatables:^1.0”安装 Yajra Datatable 时遇到问题，我遇到了错误。我卸载了 Wampp 并安装了 Xampp 但问题仍然存在。请帮我弄清楚为什么会发生这种情况是任何 PHP 版本问题或其他问题。我从两天前开始解决这个问题，但我失败了。

系统详情

操作系统Windows

PHP 7.2.11

Laravel 版本 5.7.12

Laravel-Datatables 版本 ^1.0

我刚遇到这个问题，只是 运行 这个命令。

composer require yajra/laravel-datatables

应安装最新版本的软件包，或添加此行 

"yajra/laravel-datatables": "^1.2"

到composer.json然后运行

composer update

由于 yajra/laravel-datatables-oracle，我在将 laravel 从 5.7 更新到 5.8 时遇到了问题。我从 composer.json 中删除了这个包，用 composer update 更新了 laravel，然后 composer require yajra/laravel-datatables-oracle
