python - NoSuchElementException : no such element: Unable to locate element: {"method" :"name" ,"selector" :"btnk"}

Question

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

driver = webdriver.Chrome(r"C:\Users\m\Desktop\python\selen\chromedriver.exe")
driver.set_page_load_timeout(10)
driver.get("https://google.com")
driver.find_element_by_name("q").send_keys("Automation")
driver.find_element_by_name("btnk").send_keys(Keys.ENTER)
time.sleep(4)
driver.quit()

我正在尝试这个简单的代码来打开谷歌，用上面的代码搜索一些东西。但我收到此错误消息:

Traceback (most recent call last):

Answer 1

That should be solved your problem :

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

driver = webdriver.Chrome("/usr/bin/chromedriver")
driver.set_page_load_timeout(10)
driver.get("https://google.com")
search = driver.find_element_by_name('q')
search.send_keys("google search through python")
search.send_keys(Keys.RETURN)

time.sleep(4)
driver.quit()

我在Ubuntu + chrome浏览器中测试

替换您的代码

driver.find_element_by_name("q").send_keys("Automation")
driver.find_element_by_name("btnk").send_keys(Keys.ENTER)

至=>

search = driver.find_element_by_name('q')
search.send_keys("google search through python")
search.send_keys(Keys.RETURN)
