元素带有data-v-xxx字段，无法被选择

见如下代码，在选择回答按钮的时候会提示

“Unable to locate element: div.quizcontent-button-answer:nth-child(2)”

from selenium import webdriver
import time

driver = webdriver.Firefox()

driver.get("http://192.168.0.122/dist/#/login")
driver.find_element_by_id('userName').send_keys('xxx')
driver.find_element_by_id('password').send_keys('xxxxxxx')
driver.find_element_by_xpath('//*[@id="loginBtn"]').click()
time.sleep(2)
driver.find_element_by_xpath('/html/body/div[1]/div[1]/div[1]/div/div/div[2]/div[3]').click()
time.sleep(2)
driver.find_element_by_xpath('//*[@id="tab-second"]').click()
time.sleep(2)
driver.find_element_by_xpath(
    '/html/body/div[1]/div[1]/div[2]/div/div/div[1]/div[2]/div/div/div[2]/div[6]/div[2]').click()
time.sleep(2)
driver.find_element_by_css_selector('div.quizcontent-button-answer:nth-child(2)')

错误代码如下
