[66] Error: ENOTEMPTY: directory not empty

Using symbols (:, &, #) in nuxt.config.js stops the development server and throws an error:

I found this issue when trying to use an & in my description meta data, it only occurs when the development server is running and running yarn or npm run dev again fixes the issue and the error no longer shows.

Environment: Nuxt 0.8.8, Node v7.1.0

Error while rebuild the app: { Error: ENOTEMPTY: directory not empty, rmdir '/mnt/c/Users/Anthony/Documents/acook.me/.nuxt/components'
  errno: -39,
  code: 'ENOTEMPTY',
  syscall: 'rmdir',
  path: '/mnt/c/Users/Anthony/Documents/acook.me/.nuxt/components' }
