环境：

Python 3.9.7

硒==3.141.0

问题：

我正在尝试使用 selenium 在网站上获取元素。

button_LogIn = WebDriverWait(p_driver, 10).until(EC.presence_of_element_located(
        (By.XPATH, ("//a[contains(@href,'https://www.reddit.com/login'"))))

但我收到此错误消息：

Process finished with exit code 1

我在 google 中搜索此错误消息，但找不到任何内容。

有人可以帮帮我吗？

【问题讨论】：

能否提供网站链接或显示HTML代码？
该网站是 Reddit 主页 reddit.com 我想定位登录按钮，我点击错了，Xpath 不好我再次给这行（我放弃了 Xpath 的一部分）@ 987654325@ button_LogIn = WebDriverWait(p_driver, 10).until(EC.presence_of_element_located((By.XPATH, ("//a[contains(@href,'reddit.com/login')]")))) code

标签： python python-3.x selenium

【解决方案1】：

您使用的xpath 错误。尝试以下操作，按钮将被点击。

button_LogIn = WebDriverWait(p_driver, 10).until(EC.presence_of_element_located(
        (By.XPATH, ("//*[@id='SHORTCUT_FOCUSABLE_DIV']/div[1]/header/div/div[2]/div/div[1]/a[1]"))))

# clicking the button
button_LogIn.click()

【讨论】：

Xpath 有同样的问题：-S raise exception_class(message, screen, stacktrace) selenium.common.exceptions.WebDriverException: Message: Failed to write request to stream
