以下代码：
from selenium.webdriver.firefox.firefox_binary import FirefoxBinary
from selenium import webdriver
FIREFOX_PATH = "\\".join(["C:",
"FirefoxPortable", "FirefoxPortable.exe"])
binary = FirefoxBinary(FIREFOX_PATH)
browser = webdriver.Firefox(firefox_binary=binary)
产生以下错误：
Traceback (most recent call last):

以前有人见过这种行为吗？
