我想在browserstack上运行自动化测试，这需要安装github.com/facebook/php-webdriver中的库。
我在Ubuntu 14.04上运行Apache2。
我正在遵循GitHub repo中的"获取代码"步骤，但当我尝试运行php composer.phar install时，我会收到一些警告，说我缺少包和外部。
php-webdriver: (master)$ php composer.phar install

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

也许我没有正确地在包装步骤中添加依赖项？在这一步中，我将composer.json文件更新为：
{
"name": "facebook/webdriver",
"description": "A php client for WebDriver",
"keywords": ["webdriver", "selenium", "php", "facebook"],
"homepage": "https://github.com/facebook/php-webdriver",
"type": "library",
"license": "Apache-2.0",
"support": {
"issues": "https://github.com/facebook/php-webdriver/issues",
"forum": "https://www.facebook.com/groups/phpwebdriver/",
"source": "https://github.com/facebook/php-webdriver"
},
"require": {
"php": ">=5.3.19",
"facebook/webdriver": "dev-master"
},
"require-dev": {
"phpunit/phpunit": "3.7.*",
"phpdocumentor/phpdocumentor": "2.*"
},
"autoload": {
"classmap": ["lib/"]
}
}
我是否正确添加了"facebook/webdriver": "dev-master"行？
我试着继续下一步并运行java -jar selenium-server-standalone-2.45.0.jar，但后来在终端中出现了这个错误。

关于我问题的第二部分，即运行硒罐文件，我尝试了@acfreitas bellow建议的解决方案，但仍然收到了相同的错误消息。

这里有两个问题：
第一个问题
您的composer无法解析facebook/webdrive和最低稳定性标志的依赖关系。添加"minimum-stability": "dev"
{
"name": "facebook/webdriver",
"description": "A php client for WebDriver",
"keywords": ["webdriver", "selenium", "php", "facebook"],
"homepage": "https://github.com/facebook/php-webdriver",
"type": "library",
"license": "Apache-2.0",
"support": {
"issues": "https://github.com/facebook/php-webdriver/issues",
"forum": "https://www.facebook.com/groups/phpwebdriver/",
"source": "https://github.com/facebook/php-webdriver"
},
"minimum-stability": "dev",
"require": {
"php": ">=5.3.19",
"facebook/webdriver": "dev-master"
},
"require-dev": {
"phpunit/phpunit": "3.7.*",
"phpdocumentor/phpdocumentor": "2.*"
},
"autoload": {
"classmap": ["lib/"]
}
}
并运行
$ php composer.phar install
第二个问题
端口默认的Selenium是4444。Exception in thread "main" java.net.BindException: Selenium is already running on port 4444. Or some other service is.说硒已经在运行。若你们想再次运行，你们可以终止进程为：
$ $ ps aux | grep selenium
root 3997 2.6 3.2 465024 33336 pts/0 Sl+ 15:40 0:00 java -jar selenium-server-standalone-2.45.0.jar
$ kill -9 3997
请参阅3997是关于硒过程的pid。更改你的pid。
或者使用以下命令运行selenium：
$ java -jar selenium-server-standalone-2.45.0.jar -role hub -port 4441
因此，您应该在测试中编辑主机端口。更多信息，您可以查看文档
我只是想评论一下为什么GitHub Readme页面不建议使用"最低稳定性"："dev"。这是因为这样做是个坏主意/坏做法
解决问题的一种方法是降低最低稳定性降至"dev"。但这通常是一个非常糟糕的主意，因为它适用于所有约束，因此您将得到所有包的不稳定版本。
所以请不要那样做。
