（我的firefox版本是Mozilla Firefox 63.0，所以它与here中的问题不同）
跟随https://www.obeythetestinggoat.com/book/chapter_01.html书时，出现以下错误。
Traceback (most recent call last):

运行“ pythonfunctional_tests.py”时。
其中包含以下代码
from selenium import webdriver
browser = webdriver.Firefox()
browser.get('http://localhost:8000')
assert "Django" in browser.title
我还要指出，我在Windows 10上运行Ubuntu Bash。
