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?
C:\>cd python27

All version after 2.7.9 --> comes with pip,you most remember to to selcet pip under install of Python 2.7 image.
You can try ensurepip:
From root C:\Python27 folder python -m ensurepip

If all fail just uninstall/reinstall with pip option selected.
Upgrade also pip to 18.1.
C:\Python27
λ python -m pip install --upgrade pip
  Downloading https://files.pythonhosted.org/packages/c2/d7/90f...../pip-18.1-py2.py3-none-any.whl (1.3MB)
    100% |################################| 1.3MB 706kB/s
Installing collected packages: pip
  Found existing installation: pip 9.0.1
    Uninstalling pip-9.0.1:
      Successfully uninstalled pip-9.0.1
Successfully installed pip-18.1
Test version in Scripts folder.
C:\Python27\Scripts
λ pip -V
pip 18.1 from c:\python27\lib\site-packages\pip (python 2.7)
So i have 3.7 as main version in Path,look here last in post how to use py to access all version installed
