Running a command alongwith pip gives the following error. Even the command pip -V produces the following error.
I read that the error is due to setuptools version 31.0.0 and it should be lower than 28.0.0. But the version of my setuptools is 26.1.1 and it still gives the same error.

The only solution I could find is reinstalling pip. Run these commands on your terminal
wget https://bootstrap.pypa.io/get-pip.py
sudo -H python get-pip.py --prefix=/usr/local/
However, this works only for pip, not pip3!
Upgrade your setuptools:
wget https://bootstrap.pypa.io/ez_setup.py -O - | sudo python3
Generally sudo combined with pip is considered harmful, avoid this when your system is not already broken.
Please refer to https://stackoverflow.com/a/48126778/7596504. The problem could be fixed by modifying your /usr/local/lib/python3.5/dist-packages/pip/_vendor/pkg_resources/__init__.py.

I am not able to make out how to fix this.
i followed https://chromium.googlesource.com/chromium/src/+/master/docs/linux_build_instructions.md
also referred these

Not able to get much details.
These discussions refer to PKG_CONFIG_LIBDIR but its not clear where to set this value or use it exactly.
Any inputs on what i may be missing ?
I had the same issue resolved it by installing this packages
sudo apt-get update && sudo apt-get install pkg-config
I had the same issue, and I also tried with sudo apt-get update && sudo apt-get install pkg-config as mentioned by #Rajan Palani and many other git issues comments.
But in my case
sudo apt install libpango1.0-dev
sudo apt install libcogl-pango-dev
sudo apt install libjpeg-dev
above commands helps me out to solve the issue

I have a program where I dearly need the dependency list, but pip freeze isn't working. I am running CentOS 7 and Python 2.7.5
The program runs on Python 2.4 (which I am doing as an alias in another terminal, yes, I did try the pip freeze from that terminal) and fortran95. I definitely have pip installed. I tried upgrading the Python2.7, but it says it is fine.
The the error from pip is as follows.

This is a known issue. See https://github.com/pypa/pip/issues/3764
The advice there is to try downgrading your version of pip to one that is less strict (some people find 8.1.0 works), or to uninstall the offending package, which appears to be _ipap11helper.
I've got a py2.7 project which I want to test under py3.2. For this purpose, I want to use virtualenv. I wanted to create an environment that would run 3.2 version internally:
virtualenv 3.2 -p /usr/bin/python3.2
but it failed. My default python version is 2.7 (ubuntu default settings). Here is virtualenv --version 1.10. The error output is:
Running virtualenv with interpreter /usr/bin/python3.2

I don't know what the hell is this syntax error - where does it come from... I know there was a change in try...catch statement syntax between 2.x and 3.x, but should virtualenv throw syntax errors?
I'd be grateful if someone pointed me out if there's something I'm doing wrong or if there is an installation problem on my machine.
To create a Python 3.2 virtual environment you should use the virtualenv you installed for Python 3.2. In your case that would be:
/usr/bin/virtualenv-3.2
You'll have to use a Python 3 version of virtualenv; the version you are using is installing Python 2 tools into a Python 3 virtual environment and these are not compatible.
virtualenv --python=/usr/bin/python3.2 --no-site-packages ENV
I have two python versions on my server namely 2.4 and 2.7. It is running RHEL 5.8.
I already have pip and easy_install installed on my server.
When I try to install ipython using easy_install or pip, it gives me an error which probably does not support in python 2.4.
I want to use python 2.7 for both pip and easy_install since I would want to use the latest version of the both.
What should I do to have pip and easy_install use python 2.7. Python 2.4 is installed by default by the system and I do want to keep it.
Python 2.7 is installed at another location.
Below is the traceback both for easy_install and pip. Both end up in the same error. Any kind of help is appreciated.

One way would be:
Open pip/easy_install in text editor
Check top line, it should say
#! /usr/bin/python
Change it to #!path/to/python2.7
You should check this SO question.
You may also want to consider using virtual environment through virtualenv and virtualenvwrapper to manage which version of Python your packages should use.
If you would like to easily install iPython, SciPy, MatPlotLib, etc. by downloading a .dmg, you can try here:
http://www.enthought.com/products/epd_free.php
Or if you have a academic email address:
http://www.enthought.com/products/edudownload.php
sudo /location/to/python2.7 /path/to/pip install ipython
If you have a recent version of pip, you an also try sudo pip-2.7 install ipython
I'm trying to run cython with Python2.7 installed using OSX running Mountain Lion but I get the following errors:

How can I fix this?
Thanks!
Probably what happened is that you installed cython with one version of python and are trying to run it with another. Rather than doing the standard
python setup.py build
sudo python setup.py install
Try just switching to root and both building and installing using an explicit version of python:
sudo su
/usr/bin/python setup.py build
/usr/bin/python setup.py install
(Note that this all assumes that you're installing from a source tarball).
