I am trying to compile TypeScript to JavaScript by using the npm run build command in the terminal. I figured out that in the package.jason file, I had to change the forward slashes to two backslashes. This is not working:

"build": "./node_modules/.bin/gulp"

But this is working:

"build": ".\\node_modules\\.bin\\gulp"

Has anyone been through this problem? And why is it not working with forward slashes?
