EPERM: operation not permitted, unlink

Hi,

first thanks for your module bro, and i have a little issue with rimraf, I’m working on PC computer and I use the module only to delete the content on /dist folder, I’m using npm scripts to call rimraf

"scripts": {
    "dev": "webpack-dev-server",
    "prod": "npm run clean && cross-env NODE_ENV=production webpack -p",
    "clean": "rimraf ./dist/*"
  }

the issue happens when try delete a recursive folder, in my case when try delete /images folder as this folder have others folders like /logo , /background , /icons , I move all images to /images folder and run npm run prod and works perfectly, so maybe is a little issue or maybe I’m implementing wrong rimraf.

the error log is this.

> sass-example@1.0.0 clean C:\Users\userName\Documents\sass
> rimraf ./dist/*

C:\Users\userName\Documents\sass\node_modules\rimraf\bin.js:47
      throw er
      ^

Error: EPERM: operation not permitted, unlink 'C:\Users\userName\Documents\sass\dist\images\background'
