无法将需求解析为一组可安装的软件包。yajra/laravel-datatables-oracle

Question

我正在尝试使用以下命令安装 yajra/laravel-datatables-oracle：

composer require yajra/laravel-datatables-oracle

但我收到以下错误：

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.

我的laravel框架版本是v8.83.22。

下面是我的composer.json 文件，显示了我的所有依赖项和要求

请注意，这些要求只是最低要求，例如我安装的 php 版本是 8.0.8，laravel 框架是 v8.83.22

正如一位用户提到的，您需要使用以前的版本 (9)，因为最新版本 (10) 仅支持Laravel 9.x+，而您正在使用Laravel 8.x.

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

我还看到你提到：

尝试并得到以下错误： [InvalidArgumentException] 版本 9.0 的 yajra/laravel-datatables-oracle 包具有与您的 PHP 版本、PHP 扩展和 Composer 版本不兼容的 PHP 要求： - yajra/laravel-datatables-oracle v9.0.0 需要php ^7.1.3 与您安装的版本 8.0.8 不匹配。

这意味着您正在使用PHP 8.0但yajra/laravel-datatables-oracle:^9.0仅支持7.1 <= PHP > 8.0，因此请使用这个：

composer require yajra/laravel-datatables-oracle:^9.21.2

那个版本composer.json是这样的：

"require": {
  "php": "^7.1.3|^8",
  "illuminate/database": "5.8.*|^6|^7|^8|^9",
  "illuminate/filesystem": "5.8.*|^6|^7|^8|^9",
  "illuminate/http": "5.8.*|^6|^7|^8|^9",
  "illuminate/support": "5.8.*|^6|^7|^8|^9",
  "illuminate/view": "5.8.*|^6|^7|^8|^9"
},

这意味着它将允许您使用任何 Laravel >= 5.8.x，但也允许您使用PHP >= 7.1.

Yajra 版本9.0composer.json之前不支持这一点，这就是它失败的原因：

"require": {
  "php": "^7.1.3",
  "illuminate/database": "5.8.*",
  "illuminate/filesystem": "5.8.*",
  "illuminate/http": "5.8.*",
  "illuminate/support": "5.8.*",
  "illuminate/view": "5.8.*"
},

你可以看到它只支持 Laravel 5.8 并且7.1 <= PHP > 8.0
