It is a tough situation I am dealing with. Here is short version of my problem:
I am working on Ubuntu 12.04
I would like to install Python 3.5.x with openCV library. I would also like to use pip3 for managing package installation of python.
Here is how the version of my pythons looks like
$ python --version
Python 2.7.3
$ python3 --version
Python 3.5.2
So far it looks I have achieved my goal.
When I use virtualenv to manage python3 libraries:
virtualenv -p /usr/bin/python3 py3env
source py3env/bin/activate
I see the version of my python as follows:
(py3env)yxxxxa#yxxxxa-Precision-M4800:~$ python3 --version
Python 3.2.3
I seems there is another version of python in my machine 3.2.3 messing up with the version 3.5.2 that I have installed. This is my first problem.
The second related problem is that I am unable to install pip 3. There is this error I receive due to the same python version conflict:
$ pip

What are your expert opinions about the stated problem? Any cool idea to handle this? Thanks alot in advance
This solved my first problem. Now the second problem aslo remains, how
can I install pip3 under python 3.5.2 (preferably using viretualenv) ?
Here is answer:
python3 -m virtualenv py3env
source py3env/bin/activate
Python 3.5 should have pip by default, also after above commands You can use pip:)
For example :
python -m pip install requests
EDIT:
Here You could find very good explainations if You still need install pip after create virtualenv.

When I'm trying to install any package using pip it gives an error. It shows "ImportError: No module named helpers". I tried installing the helpers module using pip but the same error occurred. I'm pasting the output of the error message. Operating System: Arch Linux.
pip2 install requests

Thanks for everyone's help. I found out the solution. When I upgraded to python 3.7 pip was broken.
Executing these commands solved the issue.
rm -rf /usr/lib/python3.7/site-packages
python3.7 -m ensurepip
pip install --upgrade pip
Same can be used with Python2 as well, just replacing 3.7 with 2.7 and pip with pip2.
A few days ago I started getting the following error when using pip (1,2 or 3) to install.

#six.add_metaclass(abc.ABCMeta)
AttributeError: 'module' object has no attribute 'add_metaclass'
I have been researching and trying to troubleshoot this issue and I have not been able to narrow down the issue.
Just prior to noticing this issue I had updated my debian system using the standard repository and had no issues of note, I had also updated a few pip modules using pip3 install --update, I believe the modules I had updated were scapy and requests
I am unable to use pip for any command that I have tried, even "pip list" or any version of pip through 3.6.
I have uninstalled and reinstalled pip, virtualenv, and tried to manually remove the six.add_metaclass-1.0* folder from my distutils folder.
Nothing I have tried has created any change that I can see and I am not able to narrow down that any issue that I see written about is indeed similar or related to this specific issue.
I am hoping to find help to narrow this problem down further, correct it or be pointed in the direction of any information that could help me.
six 1.3.0 doesn't have add_metaclass. It was released in 2013 year. Really time to upgrade it.
I found the answer to my issue. Apparently some linux versions have specific versions of pip and six that have to be installed through the distro package manager directly in order to work. There are some nuanced changes in how Debian makes use of pip, especially regarding updates, and they have coded these changes in to their package manager and not to pip. When I recompiled Python I had uninstalled the entire python framework and I went to the source url's to recombine python and to download pip and any other dependencies. I figured since I was installing directly from the source that it would be fine... If you are using CentOS, Debian,Redhat and maybe others, then you must install pip from the package manager that is managed by your distro in order to avoid running into this error somewhere down the line.
Whenever I try to install anything using pip I get the following error:
$ sudo pip install --upgrade pip

This also happens when I try to upgrade pip, install sphinx or basically any install/upgrade option using pip.
I am running Ubuntu 15.10 and using Python 2.7.10
StackOverflow has said this is a duplicate, and that there is a solution at ImportError: No module named 'pip._vendor.distlib.scripts' when I try to install fabric by python pip however the recommend solution on this post is not actually a soltuion. It does not solve my issue, nor does it appear to solve the original posters problem.
Try this:
sudo pip install --upgrade --no-use-wheel pip
I can't get the ocdev tool to run. when I try running it i receive "SyntaxError: invalid syntax" with some code.
My guess is maybe wrong python version? Since python --version outputs 2.7.3.
I also have python3 installed but it's not the standard version. I installed ocdev using pip-3.2. I already tried reinstalling it multiple times. I also have python3-jinja2 installed. I'm running debian 7.8.
Here is the whole error:

SyntaxError: invalid syntax
In order to get ocdev to work with Python 3.2 you need to install legacy versions of Jinja2(source) and MarkupSafe(source). This is because the newer versions require Python 3.3.
To do the proper install follow the regular setup guide and use the following pip/pip3 commands:
pip install -Iv Jinja2==2.6
pip install -Iv MarkupSafe==0.15
pip install ocdev
I also reported this in the ocdev GitHub repository here.
It looks like you're running Python 3.2.
To use the u'unicode' syntax with Python 3 you'll need at least Python 3.3. (see What's New In Python 3.3)
I first installed distribute, then pip with easy_install but when I run:

I get these error messages:

I do not know what to do to install virtualenv properly now?
You appear to be using Python 2.4 - try creating the virtualenv with a version of Python which includes from __future__ import absolute_import (Python 2.5 or later).
You can specify which Python to use like this:
virtualenv -p /usr/bin/python2.7
