'WebDriver' object has no attribute 'find_elements_by_xpath'

这个错误通常是因为你的WebDriver对象没有正确初始化或者没有正确调用find_elements_by_xpath方法。请确保你正确地调用了WebDriver对象的find_elements_by_xpath方法，例如：

from selenium import webdriver
driver = webdriver.Chrome()
driver.get("http://www.example.com")
elements = driver.find_elements_by_xpath("//div[@class='example']")

请注意，这个示例使用了Chrome浏览器和XPath语法来查找页面上所有class为example的div元素。你需要根据你的实际情况进行调整。

webdriver object has no attribute find_element_by_css_selector

This error message usually indicates that you are trying to use the `find_element_by_css_selector` method on the wrong object.

Most likely, you are trying to use `find_element_by_css_selector` on a `webdriver` object, which does not have this method. Instead, you should use it on a `WebElement` object.

For example, if you want to find an element by its CSS selector, you can first use the `find_element` method to locate the element, and then use the `find_element_by_css_selector` method on the resulting `WebElement` object:

# Find the parent element
parent_element = driver.find_element(By.XPATH, '//div[@class="parent"]')

# Find the child element by CSS selector
child_element = parent_element.find_element_by_css_selector('.child')

Alternatively, you can use the `find_elements_by_css_selector` method on a `webdriver` object to find multiple elements that match the CSS selector:

# Find all elements with class "my-class"
elements = driver.find_elements_by_css_selector('.my-class')

AttributeError: WebDriver object has no attribute find_elements_by_tag_name

这个错误通常是因为你尝试使用 `find_elements_by_tag_name` 方法，但是 WebDriver 对象并没有这个方法。请检查你的代码，确保你正在使用正确的方法名和对象。

如果你已经确认你的代码没有问题，你可以尝试更新你的 WebDriver 版本或者使用其他选择器方法，比如 `find_elements_by_xpath` 或者 `find_elements_by_css_selector`。
