issue installing PBIVIS on Windows PowerShell ISE

I am trying to walk-through the tutorial on Microsoft document (link below)

https://docs.microsoft.com/en-us/power-bi/developer/visuals/environment-setup?tabs=windows#install-pbiviz

I get the following error on my terminal

PS C:\Users\foldername> npm i -g powerbi-visuals-tools

How would I go about resolving this?
