python – python2.7.12 do not contain numpy also not pip so i cant run my program in gromacs

I manually download Python 2.7.12 because in my charm file the python2.7.15+ does not work.

In my Python 2.7.12 there is no pip command, so I cant install networkx & numpy packages.

What can I do to run

python JZ4 jz4_fix.mol2 jz4.str charmm36-mar2019.ff

I am trying to boostrap pip on my python 2.7.12. But that also gives an error:

suchi@DESKTOP-TR0BVV2:/mnt/c/Users/Microsoft/Desktop/Gromacs/Complex1$ python UNK1 jz4_fix.mol2
jz4.str charmm36-jul2017.ff
Traceback (most recent call last):
