Loading "gruntfile.js" tasks...ERROR >> SyntaxError: Unexpected identifier Warning: Task "default" not found. Use --force to continue

Question

This is my gruntfile.js

module.exports = function(grunt) {
grunt.loadNpmTasks('grunt-contrib-uglify');
grunt.loadNpmTasks('grunt-contrib-watch');

grunt.initConfig({
uglify:{
my_target: {
files:{
'_/js/script.js': ['_/components/js/*.js']      
}//files
}//myTarget
},//uglify
compass: {
dev:{
options: {
config: 'config.rb',                    
}//options
}//dev
},//compass
watch: {
options: {livereload: true},
scripts: {
files: ['_/components/js/*.js'],
tasks: ['uglify']       
},//scripts     
html: {
files: ['*.html']
},//html
sass: {
files: ['_/components/sass/*.scss']
tasks: ['compass:dev']
},//sass  
}//watch
})//initConfig
grunt.registerTask('default','watch'); 
}//exports

Running grunt in Command Prompt gives ERROR: Loading "gruntfile.js" tasks...ERROR >> SyntaxError: Unexpected identifier Warning: Task "default" not found. Use --force to continue.

When I comment out SASS block (in gruntfile.js)... then grunt says: Running "watch" task Waiting ... and everything is working fine!

Does anyone know what could be a problem?

To me there just seemed to be a few simple typo's, missing ,'s etc Also, try register a task like this:

grunt.registerTask('default', ['watch']);

here is a tidied up version, hopefully this works for you.

module.exports = function(grunt) {

    grunt.initConfig({
        uglify: {
            my_target: {
                files: {
                    '_/js/script.js': ['_/components/js/*.js']
                } //files
            } //myTarget
        }, //uglify
        compass: {
            dev: {
                options: {
                    config: 'config.rb'
                } //options
            } //dev
        }, //compass
        watch: {
            options: {
                livereload: true
            },
            scripts: {
                files: ['_/components/js/*.js'],
                tasks: ['uglify']
            }, //scripts     
            html: {
                files: ['*.html']
            }, //html
            sass: {
                files: ['_/components/sass/*.scss'],
                tasks: ['compass:dev']
            } //sass  
        } //watch
    }); 
    //initConfig
    grunt.loadNpmTasks('grunt-contrib-uglify');
    grunt.loadNpmTasks('grunt-contrib-watch');

    grunt.registerTask('default', ['watch']);
} //exports
