NPM Package install fails

Running this from PowerShell as an Admin. Node.js and NPM are both updated to the recent versions, and I'm getting an error at "PS C:\Program Files\nodejs\node_modules\npm\node_modules> npm i jsdoc-plugin-suitescript

jsdoc-plugin-suitescript@1.0.0 postinstall C:\Program Files\nodejs\node_modules\npm\node_modules\jsdoc-plugin-suitescr ipt cp -r plugins/ templates/ ../jsdoc

'cp' is not recognized as an internal or external command, operable program or batch file."

It looks like the the plugin is working correctly, but I'm not sure. I've attached the npm-debug.lognpm-debug.log
