Npm install error EPERM Operation not permitted

So when trying to run the angular4 project today my first error was : npm install eperm operation not permitted so I thought to delete my node modules folder and retry. But running npm install I am running in to this error npm ERR! argv "C:\\Program Files\\nodejs\\node.exe" "C:\\Program Files\\nodejs\\node_modules\\npm\\bin\\npm-cli.js" "start". I've closed vscode to try and run the install to make sure nothing was locking it. I've tried npm cache clean but results in errors.

Todays latest struggles :

0 info it worked if it ends with ok

Any suggestions?
