composer require laravel/socialite ^2.0

执行失败，错误如下：

Your requirements could not be resolved to an installable set of packages.

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

Laravel版本为5.3.22。

PHP版本为7.0.10。

在Github上，socialite2.0的composer.json显示依赖关系为guzzlehttp 5.0/6.0。为什么我的安装程序要寻找guzzlehttp 4.0？

编辑-1：

我尝试通过将其添加到composer.json require-dev中来强制使用guzzlehttp 4.2.4。

然而，我收到了以下错误：

  Problem 1
    - The requested package guzzlehttp/guzzle (locked at 6.2.2, required as 4.2.4) is satisfiable by guzzlehttp/guzzle[6.2.2] but these conflict with your requirements or minimum-stability.
  Problem 2
    - aws/aws-sdk-php 3.19.23 requires guzzlehttp/guzzle ^5.3.1|^6.2.1 -> satisfiable by guzzlehttp/guzzle[5.3.1, 5.3.2, 5.3.x-dev, 6.2.1, 6.2.2, 6.2.3, 6.3.0, 6.2.x-dev] but these conflict with your requirements or minimum-stability.
    - aws/aws-sdk-php 3.19.23 requires guzzlehttp/guzzle ^5.3.1|^6.2.1 -> satisfiable by guzzlehttp/guzzle[5.3.1, 5.3.2, 5.3.x-dev, 6.2.1, 6.2.2, 6.2.3, 6.3.0, 6.2.x-dev] but these conflict with your requirements or minimum-stability.
    - aws/aws-sdk-php 3.19.23 requires guzzlehttp/guzzle ^5.3.1|^6.2.1 -> satisfiable by guzzlehttp/guzzle[5.3.1, 5.3.2, 5.3.x-dev, 6.2.1, 6.2.2, 6.2.3, 6.3.0, 6.2.x-dev] but these conflict with your requirements or minimum-stability.
    - Installation request for aws/aws-sdk-php (locked at 3.19.23) -> satisfiable by aws/aws-sdk-php[3.19.23].

显然，aws-sdk-php需要guzzlehttp 5.3/6.2。 Laravel 5.3与socialite 3.0不兼容。 Socialite 2.0与guzzlehttp 5.3/6.2不兼容。

如何解决这个问题？

TIA

你能发布你的composer.json文件吗？ - Zoe Edwards
一种可能性是安装旧版本的aws/aws-sdk-php，例如该软件包的2.8版本。 - sk11z00
另一个解决方案是将您的 Laravel 版本更新到 5.3 或 5.4，以满足系统支持的要求。https://github.com/laravel/framework/blob/5.4/composer.json - sk11z00
@ThomasEdwards，我发布了composer.json。将guzzlehttp 4.2.4添加到require-dev中会显示aws-sdk-php依赖项。升级Laravel版本或降级aws-sdk-php需要大量的工作来验证应用程序。不幸的是，这不是一个选项。 - Krishna Chebrolu
顺便说一下，我的主要需求是允许用户从我们的网站上发布照片到FB/Twitter/G+（而不是链接）。有没有其他可用的替代方案来实现这个需求？ - Krishna Chebrolu
现在，我有一个想法，过几分钟。存在一个名为composer.lock的文件。你能删除这个文件和文件夹vendor，然后再尝试运行命令：“composer require laravel/socialite ^2.0”吗？ - sk11z00

我有一个关于这个问题的想法。
在`composer.lock`中，保存您使用composer配置下载的软件包的哈希值和版本，可以是此时或其他时间。然后删除此文件和供应商文件夹，并再次执行：
composer require laravel/socialite ^2.0

以下是问题的解决方案：原来问题很简单。由于我仍在学习Composer的功能，之前无法解决。

将版本中的^更改为~就可以解决问题。根据掌握Composer - 小技巧，波浪号（~）和脱字符（^）都应该允许包中的小版本。但是，似乎“只需注意破坏性更改”优先于允许小版本。（至少，这是我得出的结论）。

以下是结果：

composer require laravel/socialite:~2.0

尝试：

composer require laravel/socialite

希望能对您有所帮助。
请参阅：Laravel文档。
该命令将下载Socialite 3.0版本，但@krsna想要2.0版本。而Socialite 3.0版本要求Laravel的最低版本为5.4。这不是一个可选项和解决方案。 - sk11z00

版本不重要，它将正常工作。我认为他有一点困惑，如果他下载最新版本，则代码将无法运行。 - bipin

在编写文件中添加"laravel/socialite": "2.*"，然后运行 composer update和 composer dump-autoload 。

尝试这个：composer require laravel/socialite:~2.0 对我有用 :)
