Issue encountered while executing tasks in the Gruntfile.js file

Having trouble with Grunt concatenating my CSS files into one named production.css

Below is the output I received from the command prompt:

C:\Users\josha\Desktop\Repos\AJAX Project - Grunt Test>grunt

C:\Users\josha\Desktop\Repos\AJAX Project - Grunt Test\Gruntfile.js:2
  "name": "AjaxPmodule.exports = function(grunt) {
        ^
Loading "Gruntfile.js" tasks...ERROR
>> SyntaxError: Unexpected token :
Warning: Task "default" not found. Use --force to continue.

Aborted due to warnings.

C:\Users\josha\Desktop\Repos\AJAX Project - Grunt Test>grunt

C:\Users\josha\Desktop\Repos\AJAX Project - Grunt Test\Gruntfile.js:2
  "name": "AjaxPmodule.exports = function(grunt) {

>> SyntaxError: Unexpected token :
Warning: Task "default" not found. Use --force to continue.

Aborted due to warnings.

C:\Users\josha\Desktop\Repos\AJAX Project - Grunt Test>

This is a snippet of my Gruntfile:

{
  "name": "AjaxPmodule.exports = function(grunt) {

    // 1. All configuration goes here 
    grunt.initConfig({
        pkg: grunt.file.readJSON('package.json'),

concat: {   
    dist: {
        src: [
            'css/*.css', // All JS in the libs folder
        ],
        dest: 'css/production.css',
    }
}

    });

    // 3. Where we tell Grunt we plan to use this plug-in.
    grunt.loadNpmTasks('grunt-contrib-concat');

    // 4. Where we tell Grunt what to do when we type "grunt" into the terminal.
    grunt.registerTask('default', ['concat']);

};roject",
  "version": "0.1.0",
  "devDependencies": {
    "grunt": "~0.4.1",
    "grunt-contrib-concat": "^0.5.0"
  }
}

I'm utilizing grunt-contrib-concat for file concatenation, with a version of "^0.5.0"

It appears that there is some unnecessary text in your file. The correct starting point should be module.exports, and there seems to be extra content at the end.

Seems like you might have mistakenly pasted your grunt code into a snippet resembling package.json:

{
   "name": "ajaxProject",
   "version": "0.1.0",
   "devDependencies": {
      "grunt": "~0.4.1",
      "grunt-contrib-concat": "^0.5.0"
   }
}

Please try the following instead:

module.exports = function(grunt) {

    // 1. All configurations should be placed here 
    grunt.initConfig({
        pkg: grunt.file.readJSON('package.json'),

        concat: {   
            dist: {
                src: [
                    'css/*.css', // All CSS files in the libs folder
                ],
                dest: 'css/production.css',
            }
        }

    });

    // 3. Indicate Grunt plugin usage.
    grunt.loadNpmTasks('grunt-contrib-concat');

    // 4. Define tasks for when "grunt" is executed from the terminal.
    grunt.registerTask('default', ['concat']);

}
