Cannot install matplotlib for python in Visual Studio 2017

[Hiline1961]

Hello,

I'm trying to follow a Python 3.6 tutorial that wants me to install the matplotlib. But, everytime I try to install it within the Python Environments window of VS 2017 I get the following in the Output window:

----- Installing 'matplotlib' -----

Does anyone know how to fix this? I would appreciate any help.


I did find an article that said this:

You can ignore SSL errors by setting pypi.org and files.pythonhosted.org as trusted hosts.

$ pip install --trusted-host pypi.org --trusted-host files.pythonhosted.org <package_name>

I'm not sure how I would manually type that pip command in VS 2017. Can it be done? And, that isn't really a solution - it appears to be a work around.

Thank you very much!!

PS: I tried to update PIP from 10.0.1 to 18.1 and got the same certificate errors.
