Selenium 不会点击“li”元素

Question

我正在尝试在Python中使用带有Selenium的CSS选择器按下一个“li”元素。 网址。问题是：当我在 windows 计算机上运行 python 代码时，它可以工作，当我在 Linux Ubuntu 服务器上运行相同的代码时，它会出错。 这是我的代码：

WebDriverWait(self.driver, 10).until(EC.presence_of_element_located((By.CSS_SELECTOR, "li[class*=member-nav__time]"))).click()

我也试过这个（没有帮助）：

el = WebDriverWait(self.driver, 10).until(EC.element_to_be_clickable((By.CSS_SELECTOR, "li[class*=member-nav__time]")))
el.click()

我的错误是：

但一开始是“元素不可迭代”

我使用 undetected_chomedriver.Chrome.

该 URL 受 Cloudflare 保护。

如果添加行：

self.driver.save_screenshot('screenshot.png')

在你的

WebDriverWait

之前你会得到这样的图像：

您想要的网页永远不会加载。我怀疑你是否可以破解 Cloudflare 保护，它旨在防止抓取
