installing pip

[brecht83]

I have a computer with python 3.7 and pip working.
Today I installed python 2.7 and it runs.
Now I'm trying to install pip for python 2.7 and I Always get an error message.
It tells me to upgrade to a newer version but I want to use version 2.7.
Anybody any idea what the problem is?
