I successfully ran the npm run start from my windows terminal but when I am within my VisualStudio and try to run "npm run start" I get the following...

npm : The term 'npm' is not recognized as the name of a cmdlet, function, script file, or operable program. Check the spelling of the name, or if a path was included,
verify that the path is correct and try again.
