Difficulty running pip from command prompt

Question

I'm trying to install numpy on my computer following the instructions here.

I've got the command prompt working to find python after adding it to my path and I installed it from python.org which should have apparently configured pip for usage with installation, but when I try to enter pip --version in my command prompt it says that pip is not recognized as an internal or external command, operable program or batch file. Entering python -m ensurepip --default-pip yields

Looking in links: C:\Users\alecj\AppData\Local\Temp\tmpu_bljns8
Requirement already satisfied: setuptools in c:\users\alecj\appdata\local\programs\python\python37-32\lib\site-packages (39.0.1)
Requirement already satisfied: pip in c:\users\alecj\appdata\local\programs\python\python37-32\lib\site-packages (10.0.1)

which looks like it's there, but I can't check the version or do anything else with it from the command prompt. How can I get my command prompt to find pip? I tried adding the above location for pip to my path but it didn't appear to help.

Answer 1

These are my results under a clean install of Windows 10 Home:

When I download python 3.7 from https://www.python.org/downloads/, I can install python from an executable called python-3.7.0.exe found in my Downloads folder. Make sure to check the box "Add Python 3.7 to PATH".

Now, opening the Command Prompt, I can see the following:

Microsoft Windows [Version 10.0.16299.15]

C:\Users\nelsn>pip --version
pip 10.0.1 from c:\users\nelsn\appdata\local\programs\python\python37- 
32\lib\site-packages\pip (python 3.7)

C:\Users\nelsn>python -m ensurepip --default-pip
Looking in links: C:\Users\nelsn\AppData\Local\Temp\tmp2wrxm7p6
Requirement already satisfied: setuptools in c:\users\nelsn\appdata\local\programs\python\python37-32\lib\site-packages (39.0.1)
Requirement already satisfied: pip in c:\users\nelsn\appdata\local\programs\python\python37-32\lib\site-packages (10.0.1)

Next, running pip install requests definitely works for me. I can type python in the Command Prompt to enter a python repl, and import requests just fine. (Oh, and also pip install numpy just fine as well.
