我有PyVirtualDisplay == 0.2.5软件包的问题，​​该软件包用于使用虚拟显示(无头模式)运行测试

我的测试可以使用PyVirtualDisplay==0.2.1正常运行，但该软件包的最新版本(例如PyVirtualDisplay==0.2.5)存在问题.

My tests are working and running as expected with PyVirtualDisplay==0.2.1, but I have a problem with the latest version of this package (for example, PyVirtualDisplay==0.2.5).

我的代码段:

...
    def _set_up(self):

        # Creation of instance of the browser.
        self.display = Display(visible=0, size=(config.WIDTH, config.HEIGHT))
        self.display.start()
        desired = self.get_desired_capabilities(config.BROWSER)
        self.driver = webdriver.Remote(command_executor=config.ACTIVE_NODE,
                                       desired_capabilities=desired)
        # Maximize window size.
        self.driver.set_window_size(config.WIDTH, config.HEIGHT)
...

错误消息:
