[FIXED] How can I install a legacy PIP version with python 2.6.6 or python 2.7.5?

Issue

I'm struggling to install the python pip module on my centOS server which is running on python2.6.6(centOS 6) or python 2.7.5(CentOS7). Due to some reasons I'm not able to upgrade the python version to 3 or later. So in the case, how can I install a legacy PIP version line pip 20 with my python2.6 or python 2.7 platform? Thanks.

Solution

You can use get-pip.py for 2.7. Here's an example in a centos:7 Docker container:

$ python -V
Python 2.7.5
$ curl -fsSL -O https://bootstrap.pypa.io/pip/2.7/get-pip.py
$ python get-pip.py --no-python-version-warning && rm -f get-pip.py
$ python -m pip --version
pip 20.3.4 from /usr/lib/python2.7/site-packages/pip (python 2.7)

Docs: https://pip.pypa.io/en/stable/installing/#installing-with-get-pip-py. (Though admittedly, they don't go out of their way to point out the presence of the 2.6/2.7 branches, given that Python 2 is prominently EOL.)
