我正在IntelliJ和Appium上运行Android自动化测试。测试可以在Windows和Linux上正常运行，但是，我收到此错误：org.openqa.selenium.WebDriverException：处理命令时发生未知的服务器端错误。原始错误：无法从ps输出中提取“ io.appium.settings”的PID：PID用户时间命令
我越来越绝望，无法在线找到解决方案。
这些是我的帽子：
DesiredCapabilities capabilities = new DesiredCapabilities()
capabilities.setCapability("device", "Android")
//mandatory capabilities
capabilities.setCapability("deviceName", "Phoenix")
capabilities.setCapability("platformName", "Android")
capabilities.setCapability("platformVersion","4.4")
capabilities.setCapability("automationName", "UiAutomator1")
capabilities.setCapability("newCommandTimeout",1800)// trying this to let videos play w/o interrupt
//other caps

capabilities.setCapability("appActivity", LoginAppActivityName)
//capabilities.setCapability("dontStopAppOnReset",true)
//capabilities.setCapability("unicodeKeyboard", true)
capabilities.setCapability("newCommandTimeout", 1000000)
driver = new AndroidDriver(new URL("http://0.0.0.0:4723/wd/hub"), capabilities)
app = new AbstractScreen(driver){}
}
这是Appium所说的：
