I had this issue i did the following steps and i have no issues anymore:

1. Delete node_modules directory
2. Detete package-lock.json file -> very important
3. Run npm install
4. Run npm run dev

My details:

npm -v => 5.0.3 node -v => v8.1.4

"laravel-mix": "^1.2.1", "cross-env": "^5.0.1", "vue": "^2.4.1",
