I didn't found a right answer so this is the reason why i ask you. Thanks !
I tried remove python, pip, python3 and pip3 multipletimes but still same problem.
pip has dropped support for Python 2 and 3.5. You will need to use a version-specific branch, assuming that your Python version is 3.5:
curl -fsSL https://bootstrap.pypa.io/pip/3.5/get-pip.py | python3.5
get-pip.py reference: https://pip.pypa.io/en/stable/installing/#installing-with-get-pip-py

Better yet, as suggested in the comments, install a newer version of Python that is not end-of-life.

I needed to install Setuptools for a project I was doing, and I had to download Setuptools through a .tar file (don't ask), but when ran the command I needed to use to install it:
C:\Users\myname\Downloads\setuptools-51.1.1>py -2 setup.py install
It ended up with a SyntaxError:
Traceback (most recent call last):
File "setup.py", line 7, in <module>
import setuptools
File "C:\Users\myname\Downloads\setuptools-51.1.1\setuptools\__init__.py", line 16, in <module>

import pkg_resources
File "C:\Users\myname\Downloads\setuptools-51.1.1\pkg_resources\__init__.py", line 1365
raise SyntaxError(e) from e
^
SyntaxError: invalid syntax
I'm using Python 2.7.
Why is it showing the error, and how can I fix it?
Edit:
When I looked into the __init__.py file, I found that there was something called an "invalid marker":
try:
marker = packaging.markers.Marker(text)
return marker.evaluate()
except packaging.markers.InvalidMarker as e:
raise SyntaxError(e) from e
The last version of setuptools to support Python 2.7 was 44.1.1 (Jan 2020). See the changelog.
Upgrade your Python version in order to use setuptools 51.1.1.

It is a Python 3 syntax.
First install Python 3.
Then run sudo pip3 install pandas or python3 -m pip install pandas.
When trying to install the module via pip, it says I need to install setuptools 18.5 or higher. So I do a "pip install -U pip" it upgrades my pip version to 10.0.1. Then when I try to install the pywinrm module, it breaks with a Syntax Error.
In fact, it breaks all Pip commands when upgrading to 10.0.1. I have it currently installed with version 7.1.0 and Python 2.6.6
I try this:
pip install pywinrm

How fix this? I can not install any module or rollback pip.
Python 3.2
Pip 8.1.1
You need to upgrade your Python. Python 3.2 does not support Unicode string literals with the u"..." syntax (the idea was that these are not needed anymore because all string literals are Unicode in Python 3.x). This is why you are getting the error.
In Python 3.3, this feature was restored to make it easier to write code that runs on either Python 2.x or 3.x and clearly PIP is taking advantage of this.
Indeed, the documentation for PIP 8.1.1 mentions that it needs Python 3.3 or later.
I am running a python script where it is setting up an environment in unix to run other python scripts. It is trying to install pip and it fails with the following error.

2016-01-25 12:05:50,291 - Pip is not currently installed.

Failed to install pip. Error was Command '['python', '/tmp/tmpoDUDVr.py', '- -user', '--upgrade', '--force-reinstall']' returned non-zero exit status 1
I have already installed pip using the command yum -y install python-pip but still it throws this error. I am not able to find this tmp/tmpoDUDVr.py file and everytime I run this tmp file varies.I tried searching hidden files too(ls -a) Could you please shed light? Any thoughts much appreciated..
Try to use "sudo" in this case. PIP was installed the first time as root...
