Firefox可以工作，但PhantomJS抛出的元素无法找到css s

Question

我最近从webdriver.Firefox()改为webdriver.PhantomJS()以提高速度，当我试图在我的日期选择器上找到一个元素以便在之后单击它时，我开始出现一些错误

    self.driver = webdriver.PhantomJS()
    self.driver.set_window_size(1280, 1024)
    self.driver.find_element_by_css_selector(
                "#ui-datepicker-div td.full-selected.full-changeover > a"
            ).click()

Message: {"errorMessage":"Unable to find element with css selector '#ui-datepicker-div td.full-selected.full-changeover > a'","request":{"headers":{"Accept":"application/json","Accept-Encoding":"identity","Connection":"close","Content-Length":"146","Content-Type":"application/json;charset=UTF-8","Host":"127.0.0.1:54784","User-Agent":"Python-urllib/3.5"},"httpVersion":"1.1","method":"POST","post":"{\"value\": \"#ui-datepicker-div td.full-selected.full-changeover > a\", \"sessionId\": \"8b584560-6eb6-11e6-bb4a-77906b62d5cb\", \"using\": \"css selector\"}","url":"/element","urlParsed":{"anchor":"","query":"","file":"element","directory":"/","path":"/element","relative":"/element","port":"","host":"","password":"","user":"","userInfo":"","authority":"","protocol":"","source":"/element","queryKey":{},"chunks":["element"]},"urlOriginal":"/session/8b584560-6eb6-11e6-bb4a-77906b62d5cb/element"}}

我正在使用selenium==2.53.6和{}

我重现了您的问题，并通过最大化浏览器窗口修复了它：

self.driver = webdriver.PhantomJS()
self.driver.maximize_window()
