Selenium未调用driver.quit()意外关闭窗口报错（PyCharm环境）

环境与问题 #

使用最新版Selenium、PyCharm开发，Chrome版本115.0.5790.171。执行代码时浏览器打开后立刻关闭，同时抛出NoSuchElementException，提示无法定位#articalcount a元素。

涉事代码 #

from selenium import webdriver
from selenium.webdriver.common.by import By


driver = webdriver.Chrome()
driver.get(url="https://en.wikipedia.org/wiki/Main_Page")
article_count = driver.find_element(By.CSS_SELECTOR, "#articalcount a")
article_count.click()

解决步骤 #

1. 修复元素定位拼写错误
   核心问题是CSS选择器拼写错误：#articalcount应为#articlecount（少写了一个i）。维基百科主页上统计文章数量的元素ID是articlecount，修正后即可定位到元素。

2. 防止浏览器自动关闭
   代码执行完毕后Python进程结束，Selenium会默认关闭浏览器。可以通过以下方式保持浏览器打开：

   • 在代码末尾添加input("Press Enter to close...")，让程序等待用户输入后再结束；
   • 使用with语句管理driver会话，确保会话在需要时保持：

     from selenium import webdriver
     from selenium.webdriver.common.by import By
     
     with webdriver.Chrome() as driver:
         driver.get(url="https://en.wikipedia.org/wiki/Main_Page")
         article_count = driver.find_element(By.CSS_SELECTOR, "#articlecount a")
         article_count.click()
         input("Press Enter to close...")
