No Build System : Sublime Text 3

I can't seem to get the sublime build system to work, I get "No build System" when I try to run my code.

I've set build system to Automatic under Tools->Build Systems, and the file has been save as Node.sublime-build in my Sublime Text settings folder.

These are the different variations I have tried below :

{
    "cmd": ["C:\\Program Files\\nodejs\\node.exe", "$file"] 
    "selector" : "*.js"
}

{
   "cmd": ["C:\\Program Files\\nodejs\\node.exe", "$file"] 
    "selector" : "source.js"
}

{
    "cmd": ["C:/Program Files/nodejs/node.exe", "$file"] 
    "selector" : "*.js"
}

{
    "shell_cmd": ["C:\Program Files\nodejs\node.exe", "$file"] 
    "selector" : "*.js"
}
