Behat+Mink+Selenium 安装

Question

尝试安装 Behat+Mink+Selenium 时出现以下错误。有什么解决办法？

php composer.phar 安装

Loading composer repositories with package information
Installing dependencies (including require-dev) from lock file
Warning: The lock file is not up to date with the latest changes in composer.json. You may be getting outdated dependencies. Run update to update them.
Your requirements could not be resolved to an installable set of packages.

  Problem 1
    - Installation request for symfony/framework-standard-edition 2.4.x-dev -> satisfiable by symfony/framework-standard-edition[2.4.x-dev].
    - symfony/framework-standard-edition 2.4.x-dev requires behat/behat 2.4.*@stable -> no matching package found.

Potential causes:
 - A typo in the package name
 - The package is not available in a stable-enough version according to your minimum-stability setting

我正在关注这两个博客来安装它：

• Installing, configuring and running Behat on Symfony2 with Mink and Selenium Installing Behat, Mink and Selenium2 for Symfony2

Answer 1

IMO，您注册的包裹过多。例如，behat 是 symfony2 扩展的依赖项。所以，只需要要求 symfony2-extension 和 behat 将是必需的 :) 当您明确要求所有内容时，问题是您需要检查每个包约束是否可以在 packagist 上协同工作（这可能会变得很痛苦）......

对于 Symfony 2.4 项目，我会使用以下包：

"require-dev": {
    "behat/symfony2-extension": "~1.1",
    "behat/mink-extension": "~1.3",
    "behat/mink-selenium2-driver": "~1.1",
    "behat/mink-goutte-driver": "~1.0",
}

Answer 2

我建议运行 composer require，并在安装之前执行 composer update 以便所有依赖项都处于更新版本。所以下面的依赖对我的 symfony2.8 项目很有用：

composer update
composer require behat/behat
composer require behat/symfony2-extension
composer require behat/mink
composer require behat/mink-browserkit-driver
composer require behat/mink-extension
composer require behat/mink-goutte-driver
composer require behat/mink-selenium2-driver
composer require emuse/behat-html-formatter
composer require coduo/php-matcher
