Installing packages through Anaconda?

[Athenaeum]

I have successfully installed the pandas package via Anaconda. At first, I was only able to use pandas when I opened Python via Anaconda. After playing around with it for a bit, I was able to install it such that I can now import pandas and use it without ever having to open Anaconda. I could be wrong, but I think I remember using the command below to install it via cmd:

py -m pip install pandas 

I have tried to install two other packages that came with Anaconda (statsmodels and scipy) via the same method and neither works. I can use both packages, but only if I open python via Anaconda. I would like to be able to use all Anaconda packages without having to access Python through it. Do you have any idea on how to achieve this?

I would copy and paste the error message, but it is several lines long and I am not sure how to copy Python output to clipboard.

Thanks for any advice you can provide.
