How to fix ImportError: No module named packages.urllib3?

Question

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:

Answer 1

python3

#note that requests.packages.urllib3 is just an alias for urllib3
from urllib3 import disable_warnings
from urllib3.exceptions import InsecureRequestWarning
disable_warnings(InsecureRequestWarning)

Answer 2

If you already have 'requests' installed from a default build, you may have to

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

---now, how do I make this a dependency in my setup.py?

Answer 3

Problem solved by:

pip install --upgrade urllib3==1.19.1
pip install --upgrade requests

Answer 4

If you are having a RHEL based flavour, then:

yum install -y python-requests

Debian/Ubuntu based flavour:

apt-get install -y python-requests

Arch Linux based flavour:

pacman -S python-requests

Answer 5

There is a difference between the standard urllib and urllib2 and the third-party urllib3.

It looks like twill does not install the dependencies so you have to do it yourself. Twill depends on requests library which comes with and uses urllib3 behind the scenes. You also need lxml and cssselect libraries.

You can install them on terminal as follows:

pip install requests

pip install lxml

and

pip install cssselect
