为什么不能从动态下拉列表中选择以下值?

price.send_keys("50")
baseprice = driver.find_element(By.XPATH,"//*[@id='page-content']/div/div[2]/div[1]/div[1]/div/div[2]/div/div/form/div[1]/div[1]/div/div[1]/div[2]/div[2]/div/div/input")

category = driver.find_element(By.XPATH,"//*[@id='page-content']/div/div[2]/div[1]/div[1]/div/div[2]/div/div/form/div[1]/div[1]/div/div[1]/div[3]/div/div/div/div[2]")
Select.select_by_visible_text("Category 2 - BeautyPOS")
time.sleep(3)

我想从下拉列表中选择一个值，但是当我使用"select"时它不起作用。函数。我不知道有什么问题。已经尝试了许多方法来调试它，但失败了…如果有人能帮忙，我很感激，提前谢谢。
