我的硒脚本超时异常错误

Question

这是我的代码

import mouse
from selenium import webdriver
from selenium.webdriver.common.keys import Keys
from selenium.webdriver.support.ui import WebDriverWait
from selenium.webdriver.common.by import By
from selenium.webdriver.support import expected_conditions as EC
from selenium.webdriver.common.action_chains import ActionChains
import time
from time import sleep
import random


email= 'email'
password= "password"

driver = webdriver.Chrome(executable_path="C:\chromedriver.exe")
driver.get("https://www.quora.com/")
time.sleep(1)
enter_email = WebDriverWait(driver, 20).until(EC.presence_of_element_located((By.NAME, 'email')))
enter_email.send_keys(email)
print('email entered')
time.sleep(random.randint(1,5))
enter_password = WebDriverWait(driver, 20).until(EC.presence_of_element_located((By.NAME, 'password')))
enter_password.send_keys(password)
print('password entered')
time.sleep(random.randint(1,2))
enter_password.send_keys(Keys.RETURN)
print('logged in succesfull')
driver.get("https://www.quora.com/")
search = 'what i want to search'
search_for_question = WebDriverWait(driver, 20).until(EC.presence_of_element_located((By.NAME, 'search')))
search_for_question.send_keys(search)

当我运行它时，我得到了

Traceback (most recent call last):
  File "C:\Users\EL127032\PycharmProjects\quora\main.py", line 31, in <module>
    search_for_question = WebDriverWait(driver, 20).until(EC.presence_of_element_located((By.NAME, 'search')))
  File "C:\Users\EL127032\PycharmProjects\quora\venv\lib\site-packages\selenium\webdriver\support\wait.py", line 80, in until
    raise TimeoutException(message, screen, stacktrace)
selenium.common.exceptions.TimeoutException: Message: 

我不知道如何解决这个问题。我已经搜索了 google stack overflow 和 youtube。但无法解决这个问题。有人请帮助我。 （请注意，我对这种脚本没有太多经验，所以请提供您的解释证明）

您只是在那里使用了错误的定位器。
只需使用它，它就会正常工作：

search_input_css_selector = 'input.q-input'

search_for_question = WebDriverWait(driver, 20).until(EC.visibility_of_element_located((By.CSS_SELECTOR, search_input_css_selector)))
search_for_question.send_keys(search)

最好使用可见性预期条件而不是仅仅存在，因为当发现元素存在于页面上时，它通常还没有完全完成构建，尝试单击元素或发送时会花费更短的时间那个时候的文本将无法正常工作。
