ImportError: cannot import name DependencyWarning

Question

I am using python 2.7.12. When i do import requests, I see the error below.

Tried uninstalling & installing requests, upgrading pip as well, but no luck, still same issue.

Python 2.7.12 (default, Nov 19 2016, 06:48:10)
[GCC 5.4.0 20160609] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> import requests
/home/test/.local/lib/python2.7/site-packages/requests/__init__.py:80: 
RequestsDependencyWarning: urllib3 (1.13.1) or chardet (2.3.0) doesn't match a supported version!
RequestsDependencyWarning)

Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "/home/test/.local/lib/python2.7/site-packages/requests/__init__.py", line 90, in <module>
from urllib3.exceptions import DependencyWarning
ImportError: cannot import name DependencyWarning

How can I solve this?

Answer 1

I had the same error and was able to fix it by upgrading requests with the following command:

sudo pip install --upgrade requests

Answer 2

There are two cases that occur this problem.

1. There is duplicated PATH of pip.

   apt-get remove python-pip

   easy_install pip

2. This problem is caused by a mismatch between your pip installation and your requests installation.

   You can solve this issue by updating pip.

Answer 3

In my case, I changed the code like following

• Open up file: /usr/lib/python2.7/site-packages/pip/__init__.py and find this line.

  from pip._vendor.requests.packages.urllib3.exceptions import DependencyWarning

• Check if pip._vendor.request folders are there. If yes, then it must be python path issue. If no, do following.

• Remove text before urllib3 and change like this.

  from urllib3.exceptions import DependencyWarning

I will also try to make PR request about this.

Answer 4

If sudo pip install --upgrade requests didn't worked (as in my case) try to uninstall and install requests with no-cache option:

sudo pip --no-cache-dir uninstall requests
sudo pip --no-cache-dir install requests
