Cannot install virtualenv using pip - python

I first installed distribute, then pip with easy_install but when I run:
sudo pip install virtualenv
I get these error messages:
Traceback (most recent call last):

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

Pip error -> ImportError: No module named helpers

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.

An error message when execute pip

I am confused on python on its installation path and configuration.
I know pip this command for installation or listing the modules.
The example is like pip freeze. It will show up the list of module.
Recently, I got an error when I execute pip. I had python2 and python3 on the system without any virtualenv. I use ls /usr/bin/python* -al | awk {print $9 $10 $11} to know python commands and ls /usr/bin/pip* -al to know the pip commands.
python->python2.7
python2->python2.7
python2.7
python2.7-config->arm-linux-gnueabihf-python2.7-config
python2-config->python2.7-config
python3->python3.4
python3.4
python3.4m
python3m->python3.4m
python-config->python2.7-config
pip pip2 pip3
In addition, I use ls on /usr/local/bin and know the pip commands.
pip pip2 pip2.7 pip3 pip3.4 pip3.5
The error message is this when I execute pip.
Traceback (most recent call last):

How to resolve this error? Why does the system show up the error?
The result is the conflict without a specific command.
Use python2.7 -m pip or python2 -m pip for a specific command. Vice versa, on python3, use python3 -m pip or python3.4 -m pip for a specific command.
In addition, use python or python3 to get into interactive mode. Then, use import sys and sys.path to get the path of python package.

Python version conflicts and pip3

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.

Error when using pip to install

Whenever I try to install anything using pip I get the following error:
$ sudo pip install --upgrade pip

ImportError: No module named 'pip._vendor.distlib.scripts'
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

Django: ImportError: cannot import name _compare_digest

I have installed Django 1.6.5 with PIP and Python 2.7.8 from the website.
I ran django-admin.py startproject test123, switched to test123 directory, and ran the command python manage.py runserver, then i get this:

from operator import _compare_digest as compare_digest
ImportError: cannot import name _compare_digest
Found out that operator is a standard python library. Why cant it not import it?
P.S. I did try it in the command line, I can import the operator module, but I get an error on this statement: from operator import _compare_digest as compare_digest
Followed this SO answer:
Uninstall python.org version of python2.7 in favor of default OS X python2.7
Then changed my .bash_profile Python path to /usr/lib/python for the default OSX python path.
Uninstalled Django and MySQL-Python:
sudo pip uninstall django
sudo pip uninstall MySQL-Python
And then again reinstalled everything, but with MySQL-Python being the first and second Django.
After these steps, everything is working.
I get this error with anaconda as my default python and django1.7 while trying to use startproject.
I deleted the venv and recreated it with
virtualenv -p /usr/bin/python2.7 venv
startproject was working again.
You most likely have another file named operator.py on your PYTHONPATH (probably in the current working directory), which shadows the standard library operator module..
Remove or rename the file.
For those not wanting to switch to Apple's python, simply deleting the virtualenv and rebuilding it worked fine for me.
Tip: Don't forget to pip freeze > requirements.txt first if you aren't already tracking your package requirements. That way you can pip install -r requirements.txt to get up and running again quickly.
