setting correct path for P2 after uninstalling Py 3

[kwfreverie]

I installed Python 3.7 recently but discovered a script I can use which runs on Python 2.7. I read through several sets of instructions on how to run both versions on the same machine, but I also saw lots of disagreement as to what works and what doesn't.

So I uninstalled 3.7 (which was installed to the programs folder in Win 10) and cleaned my machine as best I could of any reference to 3.7.

Then reinstalled 2.7 in the C:\Python27 folder. That went fine. Next step was to install pip, so this is what happened:

C:\Python27>python get-pip.py
Requirement already up-to-date: pip in c:\python27\lib\site-package

Then I tried to use

pip install

to install some modules, but I get this:

'pip' is not recognized as an internal or external command,
operable program or batch file

.

Any advice? Thanks!
