Python requests ImportError: cannot import name HeaderParsingError

Question

OS: Mac OS X. When I'm trying to run the code below, I get the error:

ImportError: cannot import name HeaderParsingError

I've attached traceback below the code.

I've tried to solve this issue for 20 min now, using Google and other stackoverflow. I have tried running:

pip install urllib3 --upgrade

I've also tried reinstalling the requests package.

It did not help.

This seems to be an issue with my requests or urllib3 package. Has anyone had a similar issue?

The code:

import requests
import json


def printResponse(r):
print '{} {}\n'.format(json.dumps(r.json(), sort_keys=True, indent=4,    separators=(',', ': ')), r)


r = requests.get('http://wikitest.orcsoftware.com/rest/api/content',
             params={'title': 'new page'},
             auth=('seb', '****'))
printResponse(r)
parentPage = r.json()['results'][0]
pageData = {'type': 'comment', 'container': parentPage,
        'body': {'storage': {'value': "<p>A new comment</p>", 'representation': 'storage'}}}
r =    requests.post('http://localhost:8080/confluence/rest/api/content',
              data=json.dumps(pageData),
              auth=('admin', 'admin'),
              headers=({'Content-Type': 'application/json'}))
printResponse(r)

This is the traceback:

Answer 1

requests comes with its own copy of the urllib3 library, in the requests/packages subdirectory. It is this copy that is somehow broken.

Reinstall requests itself; either upgrade (you have at most version 2.1.0, given the from .packages import charade as chardet line), or reinstall the existing version.

Reinstalling with pip can be done with the --force-reinstall switch:

pip install --force-reinstall requests==2.1.0

or force an upgrade:

pip install --upgrade requests
