无法将需求解析为可安装的软件包集。yajra/laravel-数据-甲骨文

Question

我试图使用以下命令安装yajra/laravel-datatables oracle：

composer require yajra/laravel-datatables-oracle

但我得到了以下错误：

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。

Bellow是我的composer.json文件，显示了我的所有依赖项和需求。

注意，这些需求只是最低限度的需求，比如我安装了8.0.8版本的php，laravel框架是v8.83.22。

正如一位用户所提到的，您需要使用以前的版本(9)，因为最新的版本(10)只支持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：

尝试了以下错误: InvalidArgumentException包yajra/laravel-datatables-oracle在版本9.0中的PHP要求与您的PHP版本、PHP扩展和编写版本不兼容：-yajra/laravel-datatables-oraclev9.0.0需要php ^7.1.3，它与您安装的8.0.8版本不匹配。

这意味着您使用的是PHP 8.0，但yajra/laravel-datatables-oracle:^9.0只支持7.1 <= PHP > 8.0，所以请使用下面一个：

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

该版本的composer.json如下所示：

"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版本的composer.json以前不支持这一点，这就是为什么它对您失败的原因：

"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.*"
},

您可以看到它只支持Laravel5.8和7.1 <= PHP > 8.0

Answer 2

这个特定包的最新版本是10.x，它只受Laravel 9.x和更高版本的支持。

您使用的composer require将引入不受Laravel 8安装支持的版本10.x，因此向composer提供了Laravel 8.x支持的软件包的特定版本

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

你可以检查一下包GitHub页面上的版本兼容性。
