Python (pip) - RequestsDependencyWarning: urllib3 (1.9.1) or chardet (2.3.0) doesn't match a supported version

Question

I found several pages about this issue but none of them solved my problem.

Even if I do a :

pip show

I get :

/usr/local/lib/python2.7/dist-packages/requests/__init__.py:80: RequestsDependencyWarning: urllib3 (1.9.1) or chardet (2.3.0) doesn't match a supported version!
  RequestsDependencyWarning)

    from urllib3.exceptions import DependencyWarning
ImportError: cannot import name DependencyWarning

What I did :

pip install --upgrade chardet

but as explain up, it gaves me the same error.

so I did :

sudo apt remove python-chardet

and unistalling all his dependecies. After I reinstall it -> the same :'(

I did the same for python-pip. After reinstalling it -> the same.
Here are the lines about urllib3 and chardet versions needed : extract of /usr/local/lib/python2.7/dist-packages/requests/__init__.py :

    # Check urllib3 for compatibility.
    major, minor, patch = urllib3_version  # noqa: F811
    major, minor, patch = int(major), int(minor), int(patch)
    # urllib3 >= 1.21.1, <= 1.22
    assert major == 1
    assert minor >= 21
    assert minor <= 22

    # Check chardet for compatibility.
    major, minor, patch = chardet_version.split('.')[:3]
    major, minor, patch = int(major), int(minor), int(patch)
    # chardet >= 3.0.2, < 3.1.0
    assert major == 3
    assert minor < 1
    assert patch >= 2


# Check imported dependencies for compatibility.
try:
    check_compatibility(urllib3.__version__, chardet.__version__)
except (AssertionError, ValueError):
    warnings.warn("urllib3 ({0}) or chardet ({1}) doesn't match a supported "
                  "version!".format(urllib3.__version__, chardet.__version__),
                  RequestsDependencyWarning)

My versions are :

ii  python-urllib3 1.9.1-3   all HTTP library with thread-safe connection pooling for Python 
ii  python-chardet  2.3.0-1  all universal character encoding detector for Python2

I don't have no more ideas...

Thanks to you all and sorry for my english :)

This is because of different requests module installed by the OS and the python dependencies for your local installation.

It can be solved by upgrading requests:

pip install requests

or

pip3 install requests
