Can't get slick-carousel to load via bower and manifest.json?

I can’t get slick-carousel bower script to load on the page after my set-up and running Gulp.

Here screen shot of my set-up.

bower.json file:

{
  "name": "sage",
  "homepage": "https://roots.io/sage/",
  "authors": [
"Ben Word <ben@benword.com>"
  ],
  "license": "MIT",
  "private": true,
  "dependencies": {
"bootstrap": "git://github.com/twbs/bootstrap.git#v4.0.0-alpha.6",
"slick-carousel": "^1.6.0",
"headroom.js": "^0.9.3"
  }
}

manifest.json file

    {
      "dependencies": {
        "main.js": {
          "bower": ["slick-carousel"],
          "files": [
            "scripts/main.js"
          ],
          "main": true
        },
        "main.css": {
          "files": [
            "styles/main.scss"
          ],
          "main": true
        },
        "customizer.js": {
          "files": [
            "scripts/customizer.js"
          ]
        },
        "jquery.js": {
          "bower": ["jquery"]
        }

I’ve been running gulp and gulp watch, when I look my source file I see only the main.js file, any suggestion?
