尝试单击“a”标签时出错 - Selenium Python

Question

我有一个非常简单的程序，它打开 https://google.com 并点击第一个 link。我已经使用 WebDriverWait 来确保该元素已准备好被点击，尽管它仍然不起作用，并且输出和错误。

代码：

from selenium import webdriver
from selenium.webdriver.support.ui import WebDriverWait
from selenium.webdriver.common.by import By
from selenium.webdriver.support import expected_conditions
import time

wd = webdriver.Firefox()

wd.get("https://www.google.com/search?q=python")

# wd.find_element_by_css_selector("a").click()  # This doesn't work, same error
WebDriverWait(wd, 1000000).until(
    expected_conditions.element_to_be_clickable((By.CSS_SELECTOR, "a"))
).click()

time.sleep(5)

wd.close()

错误：

Traceback (most recent call last):
  File "c:\Users\ketha\OneDrive\Documents\Coding\Youngwonks\InteractingWithWebsites\selenium_basics.py", line 17, in <module>
    WebDriverWait(wd, 1000000).until(
  File "C:\Users\ketha\AppData\Local\Programs\Python\Python39\lib\site-packages\selenium\webdriver\remote\webelement.py", line 80, in click
    self._execute(Command.CLICK_ELEMENT)
  File "C:\Users\ketha\AppData\Local\Programs\Python\Python39\lib\site-packages\selenium\webdriver\remote\webelement.py", line 633, in _execute
    return self._parent.execute(command, params)
  File "C:\Users\ketha\AppData\Local\Programs\Python\Python39\lib\site-packages\selenium\webdriver\remote\webdriver.py", line 321, in execute
    self.error_handler.check_response(response)
  File "C:\Users\ketha\AppData\Local\Programs\Python\Python39\lib\site-packages\selenium\webdriver\remote\errorhandler.py", line 242, in check_response
    raise exception_class(message, screen, stacktrace)
selenium.common.exceptions.ElementNotInteractableException: Message: Element <a class="gyPpGe"> could not be scrolled into view

我正在使用 Firefox。
Firefox 版本：89.0（64 位）
硒版本：3.141.0
壁虎驱动程序版本：0.29.1

您使用了错误的定位器。
绝对不是所有 a 元素都是链接，尤其是该页面上的第一个 a。
试试改用这个：

from selenium import webdriver
from selenium.webdriver.support.ui import WebDriverWait
from selenium.webdriver.common.by import By
from selenium.webdriver.support import expected_conditions
import time

wd = webdriver.Firefox()

wd.get("https://www.google.com/search?q=python")

# wd.find_element_by_css_selector("a").click()  # This doesn't work, same error
WebDriverWait(wd, 20).until(
    expected_conditions.element_to_be_clickable((By.XPATH, "//div[@id='search']//a[contains(@href,'http')]"))
).click()

time.sleep(5)

wd.close()

此外，无需为显式等待定义如此长的超时。在大多数情况下，20-30 秒就足够了。
