Unable to run npm run dev

Hi I am currently running laravel 5.4. i have node and npm installed on my windows machine I am trying to learn laravel mix but when i run the command npm run dev i receive the following error:

@JIYAAD you have to install node in your project

Navigate to your project root and run npm install to install node in your porject. Once it's done npm run dev would work

Hope it helps.

Hi I ran the command npm install and recieve the following output:

C:\wamp64\www\The-Hub>npm install
npm WARN optional SKIPPING OPTIONAL DEPENDENCY: fsevents@^1.0.0 (node_modules\chokidar\node_modules\fsevents):
npm WARN notsup SKIPPING OPTIONAL DEPENDENCY: Unsupported platform for [email protected]: wanted {"os":"darwin","arch":"any"} (current: {"os":"win32","arch":"x64"})

after that i ran the command npm run dev and recieve the follwoing output:

C:\wamp64\www\The-Hub>npm run dev

1.download node.js from Official site , use version 6 , not 7 2.after install , reopen your terminal. 3.run npm install in your project folder 4.it should be fine.

oh , by the way , please download the latest package.json file. or install a brand new laravel project which contains it .
