尝试使用Helium/Selenium登录instagram时出现查找错误

Question

所以我尝试使用Helium包登录，它在引擎盖下使用selenium，

我查看了它的文档，但我得到了一个查找错误。有谁能帮忙吗？

这是github：Helium Cheatsheet

下面是我的代码：

from helium import*
import time

start_firefox("https://www.instagram.com/")

time.sleep(5)

write('user@gmail.com', into= 'username')
write('awesome', into= 'Password')

press(ENTER)

kill_browser()

ofc这里的用户名和密码是假的:)

这是我在jupyter notebook中得到的完整错误。它可以很好地加载浏览器和instagram页面，但我当然无法登录：
