我在安装socialiteproviders / instagram时出错

Question

在我的Laravel 5应用程序中（Laravel Framework 5.6.37 ）已安装laravel / socialite，我尝试安装socialiteproviders / instagram 但出现错误：

$ composer require socialiteproviders/instagram 
Cannot create cache directory /home/serge/.composer/cache/repo/https---packagist.org/, or directory is not writable. Proceeding without cache
Cannot create cache directory /home/serge/.composer/cache/files/, or directory is not writable. Proceeding without cache

Using version ^3.0 for socialiteproviders/instagram
./composer.json has been updated

Loading composer repositories with package information
Updating dependencies (including require-dev)
Your requirements could not be resolved to an installable set of packages.

  Problem 1
    - The requested package laravel/socialite (locked at v3.1.1, required as ^3.2) is satisfiable by laravel/socialite[v3.1.1] but these conflict with your requirements or minimum-stability.


Installation failed, reverting ./composer.json to its original content.

在我的composer.json中：

我需要采取哪些步骤来安装socialiteproviders / instagram。有更好的解决方案，使laravel 5.6与instagram合作吗？

谢谢！
