How to fix ImportError: No module named packages.urllib3?
提问by Joseph John
I'm running Python 2.7.6 on an Ubuntu machine. When I run twill-sh(Twill is a browser used for testing websites) in my Terminal, I'm getting the following:
我在 Ubuntu 机器上运行 Python 2.7.6。当我twill-sh在终端中运行（Twill 是用于测试网站的浏览器）时，我得到以下信息：
Traceback (most recent call last):
File "dep.py", line 2, in <module>
import twill.commands
File "/usr/local/lib/python2.7/dist-packages/twill/__init__.py", line 52, in <module>
from shell import TwillCommandLoop
File "/usr/local/lib/python2.7/dist-packages/twill/shell.py", line 9, in <module>
from twill import commands, parse, __version__
File "/usr/local/lib/python2.7/dist-packages/twill/commands.py", line 75, in <module>
browser = TwillBrowser()
File "/usr/local/lib/python2.7/dist-packages/twill/browser.py", line 31, in __init__
from requests.packages.urllib3 import connectionpool as cpl
ImportError: No module named packages.urllib3
However, I can import urllib in Python console just fine. What could be the reason?
但是，我可以在 Python 控制台中导入 urllib 就好了。可能是什么原因？

There is a difference between the standard urlliband urllib2and the third-party urllib3.
标准urllib和urllib2和第三方之间存在差异urllib3。
It looks like twill does not install the dependencies so you have to do it yourself. Twill depends on requestslibrary which comes with and uses urllib3behind the scenes. You also need lxmland cssselectlibraries.
看起来 twill 没有安装依赖项，所以你必须自己做。斜纹取决于幕后requests附带和使用的库urllib3。您还需要lxml和cssselect库。
You can install them on terminal as follows:
您可以按如下方式在终端上安装它们：
pip install requests
pip install requests
pip install lxml
pip install lxml
and
和
pip install cssselect
pip install cssselect

If you already have 'requests' installed from a default build, you may have to
如果您已经从默认版本安装了“请求”，则可能必须
sudo pip install --upgrade requests
sudo pip install --upgrade requests

I followed these steps having the same error, I needed to use sudo pip install --upgrade each time to make it work. – bkzland Dec 17 '15 at 12:57
我按照这些步骤执行了相同的错误，我每次都需要使用 sudo pip install --upgrade 才能使其工作。– bkzland 2015 年 12 月 17 日 12:57

from urllib3.exceptions import InsecureRequestWarning
disable_warnings(InsecureRequestWarning)
