Pip on Windows won't install anything

Question

I'm trying to get Python 3.6 with numpy and openCV setup on a windows 10 machine. I have python 3.6.8 installed with pip 18.1. When I try to install anything with pip, regardless of the package, I get the same result:

C:\WINDOWS\system32>pip install numpy
Collecting numpy

  Could not find a version that satisfies the requirement numpy (from versions: )
No matching distribution found for numpy

I've tried updating pip, and it tells me that it's already up-to-date. What's going on?

I figured it out. It was some proxy issue on my company's network. Using --proxy after pip install numpy worked.

This is what I get: C:\Users\tglenn17>python3 -m pip install numpy 'python3' is not recognized as an internal or external command, operable program or batch file. I've tried "python -m pip install numpy" and it does the same as when I just do "pip install numpy" – tglenn28 Jul 01 '19 at 17:33
In the command prompt you will have to first get into the 'Scripts' folder. something like cd C:.....\Programs\Python\Python37-32\Scripts. You will have to find the path of your Scripts folder. If you search in the folder, you will get. After that try the pip install command – Devarshi Mandal Jul 01 '19 at 17:50

Try this code. This sets pypi.org and files.pythonhosted.org as trusted hosts to ignore SSL errors. pip install --trusted-host pypi.org --trusted-host files.pythonhosted.org
