Composer php 解决依赖冲突安装Behat和Laravel 5.3

您好，我正在尝试通过composer安装behat/behat，但是我有依赖性问题。我尝试了以下几种方法：

composer require behat/behat:"3.*" symfony/dependency-injection:"3.*" --dev

然而，上述的输出是

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

下面是我的composer.json文件

我应该安装behat和symfony/依赖注入的哪种组合？我尝试了许多版本，但都没有发出下面的命令

---

composer info behat/behat-a但仍然无效。

基本上，每当您陷入依赖性噩梦时，强烈建议您将所需的版本设置为特定版本，而不是使用通配符。换句话说：给作曲家更少的想象空间

这就是我所做的工作：

1.猜猜哪个最合适 Laravel 5.3于2016年9月9日发布，回顾了Behat，这是之前的第一个主要版本，于2016年3月28日发布。这是我直接在Composer中输入的第一个版本（即没有任何通配符等），如下所示：

2.运行没有附加条件的东西 之后，我只运行了以下操作：

• composer dump autoload

  ：清理缓存

• rm-rf供应商

  和

  rm composer.lock

  ：只是为了让生活更轻松

• composer安装--无脚本

  ：只是为了确保

  php artisan

  东西不会运行
• 利润

当您只需要两个软件包中的一个时，它是否有效？你能分享整个消息栈吗？
