您要达到什么目标？ （预期的行为）
我正在尝试使example.php成功运行且没有错误。
您会得到什么呢？ （实际行为）
我在日志中收到错误500和以下错误：

该问题该如何复制？ （复制步骤）
我在Raspberry Pi Model 2 B +上使用Raspbian Stretch。我将硒jar文件安装在与PHP webdriver客户端（通过Composer安装）相同的目录中，并且jar文件似乎在端口4444上运行良好。
<?php // An example of using php-webdriver.
// Do not forget to run composer install before and also have Selenium server started and listening on port 4444.
namespace Facebook\WebDriver;
use Facebook\WebDriver\Remote\DesiredCapabilities;
use Facebook\WebDriver\Remote\RemoteWebDriver;
require_once('vendor/autoload.php');
// start Chrome with 5 second timeout
$host = 'http://localhost:4444/wd/hub';
// this is the default
$capabilities = DesiredCapabilities::chrome();
$driver = RemoteWebDriver::create($host, $capabilities, 5000);
// navigate to 'http://www.seleniumhq.org/'
$driver->get('https://www.seleniumhq.org/');
// adding cookie
$driver->manage()->deleteAllCookies();
$cookie = new Cookie('cookie_name', 'cookie_value');
$driver->manage()->addCookie($cookie);
$cookies = $driver->manage()->getCookies();
print_r($cookies);
// click the link 'About'
$link = $driver->findElement( WebDriverBy::id('menu_about') );
$link->click();
// wait until the page is loaded
$driver->wait()->until( WebDriverExpectedCondition::titleContains('About') );
// print the title of the current page
echo "The title is '" . $driver->getTitle() . "'\n";
// print the URI of the current page
echo "The current URI is '" . $driver->getCurrentURL() . "'\n";
// write 'php' in the search box
$driver->findElement(WebDriverBy::id('q')) ->sendKeys('php')
// fill the search
box ->submit();
// submit the whole form
// wait at most 10 seconds until at least one result is shown
$driver->wait(10)->until(
WebDriverExpectedCondition::presenceOfAllElementsLocatedBy(WebDriverBy::className('gsc-result'))
);
// close the browser
$driver->quit();
我相信chromedriver是问题的根源，尽管我不知道如何使用命令正确安装它
wget -O /tmp/chromedriver.zip https://chromedriver.storage.googleapis.com/2.42/chromedriver_linux64.zip
&& sudo unzip /tmp/chromedriver.zip chromedriver -d /usr/local/bin/;
，然后再次在相同的硒目录中，无济于事。

答案 0 :(得分：2)
此错误消息...
PHP Fatal error: Uncaught Facebook\WebDriver\Exception\UnknownServerException: Timed out waiting for driver server to start.
...表示 WebDriver 实例无法启动驱动程序服务器。
您的主要问题是所使用的二进制版本之间的不兼容性：
https://chromedriver.storage.googleapis.com/2.42/chromedriver_linux64.zip 支持 Chrome v68-70
因此 ChromeDriver v2.42 与 Chrome浏览器v65.0
之间存在明显的不匹配@Test。
