【问题描述】：

我正在尝试遵循本指南https://www.sitepoint.com/using-selenium-with-phpunit/，以便可以使用 PHP 自动化 Chrome。我已经在 Python 中完成了这项工作，但我对 PHP 更加熟悉，所以我认为它会更容易（也许我错了......）

无论如何，当我跑步时

composer require --dev phpunit/phpunit
composer require --dev phpunit/phpunit-selenium

我从作曲家那里得到了大量关于它们如何依赖于不可能同时完成的不同事情的输出（我想，我在这里也可能是错的）。我的输出：

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

这是我的composer.json 内容

【参考方案1】：

composer require --dev phpunit/phpunit

这将安装最新的 PHPUnit，当前版本为 6.x。

composer require --dev phpunit/phpunit-selenium

然后这将尝试安装 selenium 扩展，因为它需要 PHPUnit 5.x，所以无法安装，因为您可以看到读取的输出为“问题 1”。

解决方案：明确要求 PHPUnit 5，然后要求 phpunit-selenium。

附带说明：您提供了错误的composer.json，它无法通过您提到的命令创建。它应该在 "require-dev" 下列出 PHPUnit。

【讨论】：

看起来我只是在第一次安装时省略了--dev 标志，这就是它不在正确位置的原因。我必须查找如何要求特定版本，所以我运行的命令（删除phpunit 后）是php composer.phar require --dev phpunit/phpunit "^5"，它一切正常！
