pip and python verison

[anne]

I have small issues with pip and python versions

1. MY OS reports python version 2.7.12
2. My Eclipse lets me select FOUR "interpreter" versions - from 2.7 and including 3.8
3. OS reports pip version 20.2 , but keeps asking me to update from 8.1.1.
4. I am trying to add pyqt5 to python 3.8 and getting nowhere fast

5. I have an app build in 2,7, and want to keep it for a spell.


How do I tell OS to add PyQt5 to python3.8 packages - using CLI ?

root@z-desktop:/usr/lib# pip3 install pyqt5 python3.5
Collecting pyqt5

You are using pip version 8.1.1, however version 20.2 is available.
You should consider upgrading via the 'pip install --upgrade pip' command.
root@z-desktop:/usr/lib#

pip --version
pip 20.2 from /usr/local/lib/python2.7/dist-packages/pip (python 2.7)
root@z-desktop:/usr/lib# python --version
Python 2.7.12
root@z-desktop:/usr/lib#

FYI / SOLVED (?)

You could perhaps try

Output:
python3.8 -m pip install --user PyQt5
