Selenium 服务器无法与 HTMLUnit 创建会话

Question

我已经启动了一个本地 selenium 服务器，并让它与 Chrome 一起工作，但出于某种原因我无法让它与 HTMLUnit 一起工作（我需要它，因为 chrome 对于加载我打算运行).

我这样启动 selenium 服务器：

java -jar selenium-server-standalone-3.141.59.jar

但我也尝试过这个（因为我不太确定对 htmlunit 驱动程序的依赖性应该如何工作）。无论哪种方式，都给出相同的结果：

java -cp selenium-server-standalone-3.141.59.jar:htmlunit-driver-2.33.3-jar-with-dependencies.jar org.openqa.grid.selenium.GridLauncherV3

我使用 python 绑定：

self.driver = webdriver.Remote(
command_executor='http://127.0.0.1:4444/wd/hub',
desired_capabilities=DesiredCapabilities.HTMLUNITWITHJS)

我得到的错误是：

selenium.common.exceptions.SessionNotCreatedException: Message: Unable to create session from {
  "desiredCapabilities": {
    "browserName": "htmlunit",
    "javascriptEnabled": true,
    "version": "firefox",
    "platform": "ANY"
  },
  "capabilities": {
    "firstMatch": [
      {
        "browserName": "htmlunit"
      },
      {
        "browserName": "htmlunit",
        "browserVersion": "firefox",
        "platformName": "any"
      }
    ]
  }
}

我太接近了...我所要做的就是颠倒 class 路径顺序。

java -cp htmlunit-driver-2.33.3-jar-with-dependencies.jar:selenium-server-standalone-3.141.59.jar org.openqa.grid.selenium.GridLauncherV3
