未解决的 Selenium 单击 <li> 中的 href

Question

ERROR ON "var links = driver.FindElement(By.XPath("/html/body/div[2]/div[1]/div/div/div/div[1]/div/nav/ol/ li[3]"));"

我在单击 li 标记（var 链接）中的 selenium 链接时遇到问题，尽管它可以通过手动单击。我尝试了很多方法，但还没有找到一种有效的方法；搜索stackoverflows已经存在的问题，也没有帮助。

无论我使用什么选择器类型，这都是我得到的错误 OpenQA.Selenium.NoSuchElementException：'没有这样的元素：无法找到元素

我已经请求过一次帮助，但是提供的解决方案似乎无法解决问题，所以我想我会再试一次，希望有人帮助我。
