installing pip on rhel 7.6 + failed on unknown distribution option: project_urls

we tried to installe pip on rhel machine - rhel 7.6 version ( we have python 2.7 )
as the following

we can see that installing is complain about
python_requires='>=2.7,!=3.0.*,!=3.1.*,!=3.2.*,!=3.3.*,!=3.4.*',
so we looked on setup.py
and we marked the following line - python_requires
entry_points={

"pip=pip._internal.cli.main:main",
"pip{}=pip._internal.cli.main:main".format(sys.version_info[0]),

),
],
},
zip_safe=False,
#python_requires='>=2.7,!=3.0.*,!=3.1.*,!=3.2.*,!=3.3.*,!=3.4.*', )
then we run again
installation is now better and we can see the pip is installed as
which pip
/usr/bin/pip
but last lines are:
Traceback (most recent call last):

so after re-run again the python setup.py install , installation succeeded without errors
example of last lines:
Extracting pip-20.1.1-py2.7.egg to /usr/lib/python2.7/site-packages
pip 20.1.1 is already the active version in easy-install.pth

so the workaround here was the following
marked the line as
# python_requires='>=2.7,!=3.0.*,!=3.1.*,!=3.2.*,!=3.3.*,!=3.4.*',
and run the following twice
python setup.py install
but this workaround maybe works but it is ugly
any suggestion how to fix the pip installation ?

AttributeError: 'MSVCCompiler' object has no attribute 'compiler_so'

I'm trying to run some faster r cnn tf code that I got from GitHub. All those code need to run 'make' command to run the Cython (correct me if I am wrong). But everytime I run the make command I always got the same problem for every code.
I'm using windows 10 professional with python 3.5
My tensorflow version is 1.8.0 with gpu and CUDA 9.0
here is the error from the command line :

The .compiler_so field is only present in distutils.unixcompiler.UnixCCompiler and derivatives.
So, this package does not support standard Windows build environment.
As per Build from source on Windows | TensorFlow, it's supposed to be built using MSYS2.

How can I install GDAL in Ubuntu 16,04 with python 2.7.12 using pip?

I am trying to import some specific libraries using python. it should be easy like importing numpy for example like so:
import osgeo.gdal, gdal
from osgeo.gdalconst import *
But it seemed to me like the packages gdal and osgeo are missing so I went to the project interpreter to add these packages, Sadly i did not find the package osgeo and the package gdal could not be installed ... I looked it up in the net but it seems that there is no exact way to solve the matter.
I am using Ubuntu 16,04 with python 2.7.12 and PS GDAL is Geospatial Data Abstraction Library
This the error message that I am getting:

You are using pip version 7.1.0, however version 9.0.1 is available.
You should consider upgrading via the 'pip install --upgrade pip' command.

Finally I found a solution to my problem.
sudo add-apt-repository ppa:ubuntugis/ppa
sudo apt-get update
sudo apt-get install gdal-bin
sudo apt-get -y install python-gdal
Thank you all for the contribution.

Cleaning up...

Any possible workarounds? Any help will be greatly appreciated. Thanks!

The easiest way to avoid these kind of problems is to create a virtual environment
>>>pip install virtualenv
>>>cd my_project_folder
>>>virtualenv venv
now activate your virtual environment
>>>source venv/bin/activate
now install there pip install Flask-Mail
hopefully now it should work there
if your done working then deactivate it
>>>deactivate
or
It seems like all the problem is because of certifi version conflict
so try downloading the source from here
https://pypi.python.org/pypi/certifi
and install from source
Extract it go into the folder and run this command
sudo python setup.py install
and it should work
peace

If you do not have virtual env set up I would suggest do so first. If you have that already you may need to activate that from your terminal:
>>>source venv/bin/activate
Once completed just deactivate it for your rest of the commands:
>>>deactivate

Installing Fabric On Windows (Error No Module Called Readline)

I'm trying to use the Fabric 0.1.1 deploy tool (http://docs.fabfile.org/) on Windows and we're running into an issue with the readline module. I've been through various threads but can't seem to solve the issue. It's important because we can't deploy applications from Windows based machines.

Has anybody solved this issue or can anybody suggest a workaround?

The readline module you are trying to install with easy_install is for OS X, not windows. There are Windows-compatible replacements for readline out there but perhaps you should first try updating fabric itself to a more current version (0.9 is out there now).
Grepping the source of the 0.9 version does not find any dependencies on readline.

Following these steps exactly worked for me:
1) Installed using the MSI installer for x86 from here.
2) Installed in the default C:\Python27 directory.
3) Create a new directory: C:\Python27\Scripts
4) Added C:\Python27 and C:\Python27\Scripts to the system path:
5) Download the distribute_setup.py from here into C:\Python27\Scripts
6) Open a command line, navigate to C:\Python27\Scripts, run: 'python distribute_setup.py'
7) now run 'easy_install pip'
8) now run 'pip install fabric'
9) You should get an error saying PyCrypto couldn't install. You can download the pre-build Windows binary from here. Run this to install PyCrypto.
10) run 'pip install fabric' again and it should say everything is installed.
11) in a different directory (let's say c:\dev\hello) create a fabfile.py and add the following code:
def hello(name="world"):
print("Hello %s!" % name)
12) cd to this directory and run 'fab hello:working'. You should see output say
Hello working!
Done.

Give this readline a try. It is a module for Windows that allows additional features in IPython that aren't native and might work with what you are trying to do.

0.1.1 is an older version, I believe. I have no problem installing Fabric on Windows with ActivePython (w/ PyPM):
C:\> pypm install fabric
Ready to perform these actions:
The following packages will be installed:
fabric-0.9.0 pycrypto-2.0.1
Get: [pypm.activestate.com] fabric 0.9.0-1
Get: [pypm.activestate.com] pycrypto 2.0.1-1
Installing fabric-0.9.0
Fixing script C:\Users\sridharr\AppData\Roaming\Python\Scripts\fab-script.py
Installing pycrypto-2.0.1

Download and run easy_install installer for your python version from http://pypi.python.org/pypi/setuptools#downloads . ie: setuptools-0.6c11.win32-py2.6.exe
On the command prompt, lauch easy_install -U fabric to install the last fabric release.

Readline should be available with Cygwin, if you want to move your entire stack in that direction.
