composer安装laravel-socialite出现版本问题

在使用composer命令：composer require laravel/socialite进行安装发生错误。
版本：laravel5.6
出现错误：```php
Your requirements could not be resolved to an installable set of packages.

Problem 1

    - laravel/socialite[v5.2.0, ..., 5.x-dev] require illuminate/http ^6.0|^7.0|^8.0 -> found illuminate/http[v6.0.0, ..., 6.x-dev, v7.0.0, ..., 7.x-dev, v8.0.0, ..., 8.x-dev] but these were not loaded, likely because it conflicts with another require.
    - Root composer.json requires laravel/socialite ^5.2 -> satisfiable by laravel/socialite[v5.2.0, v5.2.1, 5.x-dev].


Installation failed, reverting ./composer.json and ./composer.lock to their original content.

```
错误原因：laravel/socialite[v5.2.0, …, 5.x-dev]依赖的版本要laravel6.0以上，导致安装失败。
解决方法：更新laravel版本或者安装低版本的socialite
