def capture_element_screenshot(driver: webdriver, selector: str, output_file: str) -> None:

这里需要将 `webdriver` 改成 `WebDriver`，并且需要导入 `webdriver` 模块：

from selenium.webdriver.chrome.webdriver import WebDriver

def capture_element_screenshot(driver: WebDriver, selector: str, output_file: str) -> None:
    # 等待元素出现
    driver.implicitly_wait(10)
    element = driver.find_element(By.CSS_SELECTOR, selector)
    # 获取元素在页面中的位置和大小
    left, top, width, height = element.location['x'], element.location['y'], element.size['width'], element.size['height']
    right, bottom = left + width, top + height
    # 截取整个页面
    driver.save_screenshot(output_file)
    # 裁剪出指定元素对应的图片
    image = Image.open(output_file)
    element_image = image.crop((left, top, right, bottom))
    element_image.save(output_file)
