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。

注意，这些要求只是最低要求，比如我安装了版本8.0.8的php，laravel框架是v8.83.22
正如用户所提到的，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：
尝试过并得到以下错误：[InvalidArgumentException]版本9.0的包yajra/laravel datatables oracle的PHP要求与您的PHP版本、PHP扩展和Composer版本不兼容：-yajra/laravel datatables oraclev9.0.0需要PHP^7.1.3，它与您安装的版本8.0.8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，因此请使用以下内容：
composer require yajra/laravel-datatables-oracle:^9.21.2
那个版本的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 9.0版composer.json以前不支持，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和7.1 <= PHP > 8.0
该特定包的最新版本是10.x，只有Laravel9.x及更高版本才支持它。
您使用的composer require将引入Laravel 8安装不支持的10.x版本，因此请向composer提供Laravel8.x支持的包的特定版本：
composer require yajra/laravel-datatables-oracle:^9.0
您可以在软件包GitHub页面上检查版本兼容性。
