Simply fix paths in angular-cli.json

"styles": [
  "main.scss",
  "highlightjs/material-light.css",
  {"input": "assets/custom-themes/pink-bluegrey.scss", "lazy": true},
  {"input": "assets/custom-themes/deeppurple-amber.scss", "lazy": true},
  {"input": "assets/custom-themes/indigo-pink.scss", "lazy": true},
  {"input": "assets/custom-themes/purple-green.scss", "lazy": true}
],

This may be caused by not building the themes. I put the steps you need to run locally in #425 (comment).
