I'm trying to install yajra/laravel-datatables-oracle using the command:

composer require yajra/laravel-datatables-oracle

But I'm getting the following error:

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.

My laravel framework version is v8.83.22.

Note that the requirements are just the minimum such as php from which I have version 8.0.8 installed and laravel framework is v8.83.22

CodePudding user response：

The most recent version of that particular package is 10.x which is only supported by Laravel 9.x and above.

The composer require you're using will pull in version 10.x which isn't supported by your Laravel 8 installation, therefore provide composer with the specific version of the package that is supported for Laravel 8.x:

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

You can check version compatibility on the package GitHub page.

CodePudding user response：

As a user mentioned, you need to use the previous version (9) because the latest one (10) is only supporting Laravel 9.x and you are using Laravel 8.x.

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

I also saw you mentioned:

Tried that and got the following error: [InvalidArgumentException] Package yajra/laravel-datatables-oracle at version 9.0 has a PHP requirement incompatible with your PHP version, PHP extensions and Composer version: - yajra/laravel-datatables-oracle v9.0.0 requires php ^7.1.3 which does not match your installed version 8.0.8.

That means you are using PHP 8.0 but yajra/laravel-datatables-oracle:^9.0 only supports 7.1 <= PHP > 8.0, so instead use this one:

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

That version's composer.json is like this:

"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"
},

Meaning that it will allow you to use any Laravel >= 5.8.x but also allow you to use PHP >= 7.1.

Yajra version 9.0 composer.json did not support that before, that is why it is failing for you:

"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.*"
},

You can see it only supported Laravel 5.8 and 7.1 <= PHP > 8.0
