Why don't you just uninstall the package you've installed manually to
/usr/local? It seems to me you don't need it.

Yes, but probably from Wheezy when before Jessie became the new stable. 
My dpkg -l shows:

With /usr/local/lib/python2.7/dist-packages/requestsRENAMED
$ python -c "import requests; print requests.__version__"
2.4.3
$ python -c "from requests.compat import IncompleteRead"
$

With the original /usr/local/lib/python2.7/dist-packages/requests:
$ python -c "import requests; print requests.__version__"
2.9.1
$ python -c "from requests.compat import IncompleteRead"
Traceback (most recent call last):
  File "", line 1, in 
ImportError: cannot import name IncompleteRead

I tried "apt-get purge python-pip python-requests" and then reinstalling 
them to see if the problem would go away. Nope:
$ pip

Again, I renamed the old requests directory for me to use pip again. :(

Hello,
sorry for the delay in my reply!

03_export-IncompleteRead.patch is still present in the requests packaging 
(since pip version in Debian still need it) and was shipped with requests 
2.4.3-2.

@Ant Dude: just to recap and to be sure I understand correctly: you should 
have installed requests 2.4.3-6 and python-pip (1.5.6-5), right?
Renaming requests (Debian packaged version) install directory make pip work, 
right?
Debian packaged version of pip doesn't use convenience copies, so do you have 
a version of requests installed not using apt?
Please can you tell me what is the output of the following?

python -c "import requests; print requests.__version__"

Please, can you also try:

python -c "from requests.compat import IncompleteRead"

Thanks!

He previously said he renamed the /usr/local version, not the packaged
version:

/usr/local/lib/python2.7/dist-packages/requestsRENAMED

I think he might be getting confused where the files are coming from and
the difference between "apt-get install python-xyz" vs "pip install
xyz".

So I will try to explain: If you install the package with "pip install
xyz" - it will get installed under /usr/local. However the Debian
package system doesn't understand this, and doesn't know that you have
done this. So you may have installed a version that is not compatible
with the Debian packages.

When you install a package with "apt-get install python-xyz" (including
security updates) it will get installed under /usr/lib. The package
system knows about these packages and will work to ensure that the
versions are compatible. However any packages you have installed locally
with "pip install xyz" in /usr/local will take priority and get used
instead. Even if they are not compatible.

So as a result, it is not a good idea to install any packages locally in
/usr/local - you should always install packages with "apt-get" as only
these packages are tested by Debian to work with Debian packages.

Just to confuse matters, there are some upstream packages - particular
those not yet in Debian, where the upstream authors do recommend
installing missing dependancies with "pip install xyz" - this is not
actually good practise.

Hope this helps.

Are you sure? This bug was supposedly fixed in the Jessie version...

Maybe it is a different issue? Pip is still working so far with that

Interesting. I did find a fix and it seems like others had the same 
problem. FFrom Debian's forum, it said 
https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=744145#31 -- rm -rf 
/usr/local/lib/python2.7/dist-packages/requests* I renamed request 
directory and now can run Debian's pip command. Sheesh. I also notice it 
is an old bug that is still not fixed. :(
