Configuring VSCode to use pip

Question

I am trying to set up VSCode to allow me to run Python programs.

I am on Windows 10.

Currently, it works fine if I create simple programs like:

# This all works fine
print("Hello World")
arr = [1,2,3]
print(arr)

However, when I go to use any external library, like numpy, I get the following error:

Traceback (most recent call last): File "c:/Users/jerry/Desktop/hello.py", line 3, in import numpy as np ImportError: No module named 'numpy'

So, I issue the following in my VSCode Terminal Window: pip install numpy

Which yields me the folowing:

PS C:\Users\jerry> pip install numpy
Collecting numpy

You are using pip version 7.1.2, however version 19.0.3 is available.
You should consider upgrading via the 'python -m pip install --upgrade pip' command.

I am unsure what to do, or how to fix this error. I have reviewed the following resources:

Neither had a workable solution. Any advice or assistance would be appreciated.

Two things. One, don't use `pip` as a command as you don't know what Python interpreter it is tied to; always use `-m pip` with the Python interpreter you want to install for. — Brett Cannon, Mar 20 '19 at 18:58
Two, you can try upgrading pip as the message at the end suggests: `python -m pip install --upgrade pip` while substituting `python` with the appropriate Python interpreter. — Brett Cannon, Mar 20 '19 at 18:59
Thanks for the suggestion @BrettCannon. Unfortunately, I try upgrading pip but get the exact same error message. — artemis, Mar 20 '19 at 19:01

This was due to an issue with a proxy server that was fixed with my firewall settings. The issue for me was the need to add a specific certificate authority that hosts an intranet-only collection of Python libraries.

That certificate authority and certificate are proprietary and cannot be posted.
