python Mechanize ValueError:需要超过1个值才能解压

Question

有人能帮我吗？ 这是我的代码：

from mechanize import Browser
import re


user_agent = 'Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.9.0.7$'
br = Browser()
br.set_handle_robots(False)
br.set_handle_refresh(False)
br.addheaders = user_agent 

req = br.open("https://google.com")
date = req.read()

我得到的错误是：

Traceback (most recent call last):
File "vpnbook.py", line 12, in <module>
req = br.open("https://www.google.com")
File "/home/grimm/.local/lib/python2.7/site-packages/mechanize

return self._mech_open(url_or_request, data, timeout=timeout)

/_urllib2_fork.py", line 1104, in do_request_
for name, value in self.parent.addheaders:
ValueError: need more than 1 value to unpacky 

我正在使用Python2.7和Ubuntu18.04仿生版
