Installing av lib on Raspi3 failing

Excuse me if this is a noob's question, but I am blank if it comes to Python...
I am trying to install the Python av library on a Raspberry Pi 3. But all I get is
pi#raspberrypi:~/camera_proxy $ sudo pip install av
Looking in indexes: https://pypi.org/simple, https://www.piwheels.org/simple

----------------------------------------
Command "python setup.py egg_info" failed with error code 1 in /tmp/pip-install-Mwk4pG/av/
I already purged and reinstalled all Python (1&3) to no avail. The Raspbian is the latest stable release.
There seems to be a quote item not found, that supposedly would be part of the shlex library?

The solution for me was to use pip3 instead of pip.

Issues installing python mplcursors

I tried to install mplcursers to my PC.
I tried:
pip install mplcursors
It gave me error as:
Collecting mplcursors
Could not find a version that satisfies the requirement mplcursors (from versions: )
No matching distribution found for mplcursors
I also tried:
pip install git+https://github.com/anntzer/mplcursors
It gave me error as:
Collecting git+https://github.com/anntzer/mplcursors
Cloning https://github.com/anntzer/mplcursors to /tmp/pip-VP7mtD-build

Anyone has idea how I can solve the issue and install the mplcursors?

Try
!pip install plotly
It is working for me hope will work for you as well

pip install asteval fails on six dependency

If I create a clean virtualenv, upgrade my pip version to 9.0.1 (most recent), and try:
$ pip install asteval
Collecting asteval
Downloading asteval-0.9.10.tar.gz
Complete output from command python setup.py egg_info:

import six
ImportError: No module named six
----------------------------------------
Command "python setup.py egg_info" failed with error code 1 in /tmp/pip-build-nnWnaR/asteval/
Maybe I'm missing something, I thought pip should handle the dependencies? I thought it used to.
The bypass is to separately pip install six, then asteval will install. But I want to require asteval as an import requirement in my code, and I don't want to have to trace dependencies it might have and list those as requirements.

asteval is making a common mistake: importing itself into its setup.py. You should file a bug against the project, asking them to stop doing that.

Read the Docs: Distutils2 error during installation

I try to install local instance of Read the Docs on my Win10
When I follow this documentation:
http://docs.readthedocs.io/en/latest/install.html
and type:
pip install -r requirements.txt
I get this error:
Collecting Distutils2==1.0a3 (from -r requirements/pip.txt (line 65))

Anyone know this error?
My pip version: 8.1.2;
python: 3.5

Is it possible you are running the Python 2 pip? The error message clearly indicates that the code is being executed under Python 3 but has Python 2 syntax. Do you get better results with
python -m pip install -r requirements.txt
I wonder? If not then verify that
python
runs version 3.5 ...
Oh. I just checked and the disutils2 page on PyPI says
Distutils2 development is stopped.
tl;dr: keep using setuptools and pip for now, don’t use distutils2.
It looks like there was never a Python 3 version. Looks like you might need to update your code.

unable to import evernote.api.client (evernte sdk)

i'm trying to get started with evernote SDK , i'm using ubuntu 13.04
i installed the SDK via :
pip install evernote
but when i want to test it using :
python -c 'from evernote.api.client import EvernoteClient'
i got this :
Traceback (most recent call last):
File "<string>", line 1, in <module>
ImportError: No module named api.client
What is the problem ?
EDIT : pip install evernote works fine i guess , it gives me this :
Requirement already satisfied (use --upgrade to upgrade): evernote in /usr/local/lib/python2.7/dist-packages/evernote-1.24.0-py2.7.egg
Requirement already satisfied (use --upgrade to upgrade): oauth2 in /usr/lib/python2.7/dist-packages (from evernote)
Requirement already satisfied (use --upgrade to upgrade): httplib2 in /usr/lib/python2.7/dist-packages (from oauth2->evernote)
Cleaning up...
here is the turorial : http://dev.evernote.com/start/guides/python.php

This is pretty old already, but I bet more people will hit it, so I'll put the answer here. It seems to be a surprisingly common issue that doesn't have an answer anywhere.
Note how the error complains about api.client but not evernote.
Traceback (most recent call last):
File "<string>", line 1, in <module>
ImportError: No module named api.client
Most likely, the problem is that OP has a script in his path called evernote.py, which I guess is a common name people use to name their first evernote script. Rename the script to something less obvious and that should do the trick.

Looks like
pip install evernote don't do what it is suppose to do:
cat /etc/SuSE-release
openSUSE 12.2 (x86_64)
VERSION = 12.2
CODENAME = Mantis
pip install evernote

You can fix that with:
pip -v install evernote==1.23.2
and everything works just fine!

Could you check the version of Evernote SDK for Python with:
pip freeze
If import evernote works but from evernote.api.client import EvernoteClient doesn't, you might happen to use 1.23.0 version or older since EvernoteClient class was introduced in 1.23.1.
Also please check your site-packages directory to make sure any older version is not loaded.
