How to install argparse for python 2.7

Question

[Fede_Santos95]

Hi guys,

I've to install argparse package for phyton version 2.7.

I tried with the following command:

python2 -m pip install argparse

and the shell returned me

Defaulting to user installation because normal site-packages is not writeable
Requirement already satisfied: argparse in /usr/lib/python2.7 (1.2.1)

When I ran the following command:

pip list

argparse didn't figure among the installed packages of python, since I found:

Package         Version
--------------- -------
bitarray        2.1.0
joblib          0.14.1
numpy           1.16.6
pandas          0.24.2
pip             20.3.4

setuptools      44.1.1
six             1.16.0

How can I install this package?

my python version is:

[GCC 9.3.0] on linux2

my pip version is:

pip 20.3.4 from /usr/local/lib/python2.7/dist-packages/pip (python 2.7)

my server system is:

Have you tried removing and re-installing argparse?

[Fede_Santos95]

When I run the following command to uninstall argparse:

pip uninstall argparse

I found:

Found existing installation: argparse 1.2.1
Not uninstalling argparse at /usr/lib/python2.7, as it is in the standard library.
Can't uninstall 'argparse'. No files were found to uninstall.

I guess you should be able to import it directly, without explicit installation.

Try running: import argparse on python interpreter and see what happens. Usually, it should be ok.

argparse is in the standard python library - you probably should not install it. Do you have a problem when you just try to import it?

[Fede_Santos95]

I've tried to import it in the interactive shell of python and it seems that it works. Thank u so much to all of you!
