laravelでsocialiteの利用

Question

laravel5.1です。
socialiteを使用としています。

composer require laravel/socialite

とやってみたところエラーが出ました。

./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
    - illuminate/support 5.5.x-dev requires php >=7.0 -> your PHP version (5.6.28RC1) does not satisfy that requirement.
    - Conclusion: remove laravel/framework v5.1.45
    - Conclusion: don't install laravel/framework v5.1.45
    - laravel/socialite 3.0.x-dev requires illuminate/support ~5.4 -> satisfiable by illuminate/support[5.4.x-dev, 5.5.x-dev, v5.4.0, v5.4.9].
    - laravel/socialite 3.0.x-dev requires illuminate/support ~5.4 -> satisfiable by illuminate/support[5.4.x-dev, 5.5.x-dev, v5.4.0, v5.4.9].
    - laravel/socialite v3.0.0 requires illuminate/support ~5.4 -> satisfiable by illuminate/support[5.4.x-dev, 5.5.x-dev, v5.4.0, v5.4.9].
    - laravel/socialite v3.0.2 requires illuminate/support ~5.4 -> satisfiable by illuminate/support[5.4.x-dev, 5.5.x-dev, v5.4.0, v5.4.9].
    - laravel/socialite v3.0.3 requires illuminate/support ~5.4 -> satisfiable by illuminate/support[5.4.x-dev, 5.5.x-dev, v5.4.0, v5.4.9].
    - don't install illuminate/support 5.4.x-dev|don't install laravel/framework v5.1.45
    - don't install illuminate/support v5.4.0|don't install laravel/framework v5.1.45
    - don't install illuminate/support v5.4.9|don't install laravel/framework v5.1.45
    - Installation request for laravel/framework (locked at v5.1.45, required as 5.1.*) -> satisfiable by laravel/framework[v5.1.45].
    - Installation request for laravel/socialite ^3.0 -> satisfiable by laravel/socialite[3.0.x-dev, v3.0.0, v3.0.2, v3.0.3].


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

恐らくsocialiteのバージョンとlaravelのバージョンがあってないのかな？と思ったのですが、いまいち初心者なのでよく分かりません…。

どのようにすればsocialiteが使用できるようになるのでしょうか。
よろしくお願いします。

Answer 1

--ignore-platform-reqsを付加してみてはどうでしょうか？

composer require --ignore-platform-reqs laravel/socialite
