【问题描述】：
我制作了一个 youtube 自动化机器人。我收到错误：无法定位元素（对于订阅按钮的 Xpath）
这是我的代码

executable_path=GeckoDriverManager().install(), firefox_profile=profile)
self.bot = driver
# self.bot.maximize_window()
self.bot.set_window_size(400, 700)

我该如何解决这个问题。我无法理解哪里出了问题。或者我应该尝试通过 id 或其他方式而不是 Xpath 查找元素。 或者有什么软件有问题。 请帮帮我
【问题讨论】：
-
你的 xpath 被塑造成易碎的。假设这不是问题，时间可能是。您应该对元素使用等待。
-
您收到错误的代码行是什么？什么
xpath不起作用？是的，你的xpaths 很糟糕。你不应该使用绝对的xpaths。 -
你能多指导我一点吗？等待元素部分，任何我可以参考和指导我的来源@DMart
-
我在第 65 行遇到错误，你能告诉我创建或找到完美相对 xpath 的方法吗？ @先知
-
没有“方法”，你应该学习如何构建
xpath表达式。有很多免费的简短教程
