In a new Laravel install I get the following error when I run `npm run dev`: `Module not found: Error: Can't resolve 'bootstrap' in 'path/here/resources/js'`

In my `package.json` under `devDependencies` I have `"bootstrap": "^4.0.0"` and I haven't edited anything.

Original Laravel bootstrap.js (this is Laravel's own bootstrap file, not the one from getbootstrap.com) can be found [here](https://github.com/laravel/laravel/blob/master/resources/js/bootstrap.js).
