爬取网页出现'WebDriver' object has no attribute 'find_element_by_css_selector'

这个问题通常是由于 WebDriver 对象没有正确地初始化导致的。您需要先创建一个 WebDriver 对象，然后才能使用它来查找元素。请确保您的代码正确地实例化了 WebDriver 对象，并尝试使用该对象来查找元素。您还可以尝试使用其他查找元素的方式，例如 find_element_by_xpath() 或 find_element_by_id() 等等。如果问题仍然存在，请检查是否已正确地安装 Selenium 库，并确保您的浏览器驱动程序与您的浏览器版本相匹配。

WebDriver object has no attribute find_element_by_css_selector

`WebDriver`对象没有`find_element_by_css_selector`属性的错误通常是由于导入的模块不正确或使用了错误的方法导致的。正确的方法是使用`By`类来指定选择器类型，并使用`find_element`方法来查找元素。

以下是一个示例代码，演示如何使用`WebDriver`对象的`find_element`方法和`By.CSS_SELECTOR`来查找元素：

from selenium import webdriver
from selenium.webdriver.common.by import By

# 创建WebDriver对象
driver = webdriver.Chrome()

# 打开网页
driver.get("https://www.example.com")

# 使用CSS选择器查找元素
element = driver.find_element(By.CSS_SELECTOR, "选择器路径")

# 打印元素文本
print(element.text)

# 关闭浏览器
driver.quit()

请注意，你需要根据实际情况替换示例代码中的网页URL和选择器路径。

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')
