php - Composer 无法安装 laravel/socialite 2.0

Question

Composer 需要 laravel/socialite ^2.0

因以下错误而失败:

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

  Problem 1
    - Installation request for laravel/socialite 2.0 -> satisfiable by laravel/socialite[v2.0.0].
    - Conclusion: remove guzzlehttp/guzzle 6.2.2
    - Conclusion: don't install guzzlehttp/guzzle 6.2.2

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

Laravel 版本是 5.3.22

PHP 版本为 7.0.10

composer.json of socialite2.0在 github 上将依赖项显示为 guzzlehttp 5.0/6.0。为什么我的安装寻找 guzzlehttp 4.0？

EDIT-1:

我试图通过在 composer.json require-dev 中添加它来强制 guzzlehttp 4.2.4。

但是，我收到以下错误:

  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？

TIA

EDIT-2:

我的 composer.json 包含以下内容:

Answer 1

问题是这样解决的:原来很简单。由于我仍在学习 composer 可以做什么，所以我之前无法弄清楚。

在版本中从 ^ 更改为 ~ 就成功了。根据 Mastering Composer - tips & tricks ，波浪号 (~) 和插入符 (^) 都应该允许包中的次要版本。但是，似乎“只注意中断更改”优先于允许次要版本。 (至少，这是我得出的结论)。

结果如下:
