Grunt executes multiple times, creates infinite loop - node.js

Question

We are working as on a project with a couple of other devs on GIT, using the same repo, it works fine with everyone else. However, when I run grunt it executes multiple times, seems to be running into an infinite loop, without me actually making any changes. It's only happening to me on a different computer
I am considering that maybe I need something else installed.
I deleted node, npm and reinstalled with homebrew which I'm also using for updates. Node v5.3.0, npm 3.3.12
Running Mavericks.
What am I missing?
Here's the loop:
Reloading watch config...
Running "watch" task
Waiting...
>> File "Gruntfile.js" changed.
>> File "js/all-js/bootstrap-hover-dropdown.min.js" changed.
>> File "js/all-js/site.js" changed.
Running "uglify:build" (uglify) task
>> 1 file created.
Done, without errors.

Here's my Gruntfile.js:
module.exports = function(grunt) {
//Get all tasks from the package.json file
require("matchdep").filterDev("grunt-*").forEach(grunt.loadNpmTasks);
grunt.initConfig({
pkg: grunt.file.readJSON('package.json'),
/* Concurrent Task */
concurrent: {
watch: {
tasks: ['watch', 'compass:dist', 'browserSync'],
options: {
logConcurrentOutput: true
}
}
},
/* SASS task */
compass: {
dist: {
options: {
sassDir: ['SASS/'],
cssDir: ['css/'],
environment: 'development', /* development | production */
importPath: ['SASS/'],
outputStyle: 'compressed', /* expanded for development | compressed for production */
watch: true,
sourcemap: true
},
},
live: {
options: {
sassDir: ['SASS/'],
cssDir: ['css/'],
environment: 'production', /* development | production */
importPath: ['SASS/'],
outputStyle: 'compressed', /* expanded for development | compressed for production */
watch: false,
force: true,
},
},
},
/* Javascript Tasks */
uglify: {
// Uglify files
build: {
src: [
'js/all-js/bootstrap.js',
'js/all-js/site.js'
],
dest: 'js/site.min.js'
}
},
/* Run tasks when needed */
watch: {
js: {
files: ['js/all-js/*.js'],
tasks: ['uglify'],
options: { livereload: true }
},
gruntfile: {
files: ['Gruntfile.js'],
options: {reload: true}
}
},
/* Browser Reload with BrowserSync */
browserSync: {
bsFiles: {
src : [
'css/**/*.css',
'js/site.min.js',
'**/*.php'
]
},
}
});
// Where we tell Grunt what to do when we type "grunt" into the terminal.
grunt.registerTask('default', ['concurrent:watch']);
grunt.registerTask('live', ['compass:live']);
};
Here's my package.json file:
{
"name": "ourframework",
"version": "0.1.0",
"devDependencies": {
"grunt": "~0.4.1",
"grunt-contrib-compass": "*",
"grunt-browser-sync": "*",
"grunt-contrib-watch": "*",
"grunt-concurrent": "*",
"grunt-contrib-uglify": "*",
"matchdep": "*"
}
}

Look at the timestamps in the grunt output, eg:
Completed in 3.740s at Tue Jan 05 2016 13:11:10
Completed in 1.885s at Tue Jan 05 2016 13:12:04
Notice these compilations are a minute apart - you are running the grunt watch task. This will watch a set of specified files and re-run tasks if there are any changes.
There is no 'loop' - it will simply re-compile every time something changes, which is often desirable.
You can see your default task is set to concurrent:watch
grunt.registerTask('default', ['concurrent:watch']);
So if you just type grunt, it will run that task.
