Selenium PhantomJs Python无法找到元素

-1

我正在尝试使用无头浏览器。但是，当我尝试将.sendkeys添加到xpath选择器时，我不断收到错误。Selenium PhantomJs Python无法找到元素

from selenium import webdriver 
import time 
from selenium.webdriver.common.keys import Keys 
import time 



driver=webdriver.PhantomJS("C:\\Users\\ikhan\\AppData\\Local\\Programs\\Python\\Python36-32\\selenium\\webdriver\\phantomjs.exe") 
driver.maximize_window() 
driver.set_page_load_timeout(30) 
driver.implicitly_wait(20) 
driver.get("https://google.com") 
driver.find_element_by_xpath('''//*[@id="lst-ib"]''').send_keys("anish") 
driver.find_element_by_xpath('''//*[@id="lst-ib"]''').send_keys(Keys.RETURN) 

driver.close()

我得到以下错误：

我曾尝试使用Chrome浏览器使用此代码和它工作得很好。我也尝试使用ID选择器。

我有同样的问题。我使用'time.sleep'而不是'driver.implicitly_wait'，它工作。 – nutmeg64

是的，我试过这个不同的网站，它工作正常。我认为它只是超时 –

为什么你使用XPath找到一个简单的ID？使用'.find_element_by_id（）'。错误消息指出无法找到该元素。这可能是由于很多原因...定位器是错误的，元素尚不可用，等等。你试图找到它？ – JeffC

要找到谷歌搜索框使用name定位如下：

from selenium import webdriver 
from selenium.webdriver.common.keys import Keys 

driver = webdriver.PhantomJS(executable_path="C:\\Utility\\phantomjs-2.1.1-windows\\bin\\phantomjs.exe") 
driver.get("https://google.com") 
google_search = driver.find_element_by_name("q") 
google_search.send_keys("anish") 
google_search.send_keys(Keys.RETURN) 
print("Google Search Complete")
