Could not create a minified css file using grunt-contrib-cssmin - gruntjs

I am using grunt first time, I could able to concat css file using grunt-contrib-concat but I am getting following error while creating minified css file using grunt-conrib-cssmin
Error is :
>> TypeError: Cannot call method 'clone' of undefined
Warning: CSS minification failed. Use --force to continue.
My package.json file is :
{
"name": "grunt-test-project",
"description":"testing grunt css and js files minification",
"repository":"",
"version": "0.1.0",
"devDependencies": {
"grunt": "~0.4.5",
"grunt-contrib-concat": "~0.5.0",
"grunt-contrib-cssmin" : "~0.10.0"
}
}
My Gruntfile.js file is :
module.exports = function(grunt) {
// Project configuration.
grunt.initConfig({
pkg: grunt.file.readJSON('package.json'),
concat: {
css: {
src: [
'css/popup.css', 'css/styles_layouts.css', 'css/style.css', 'css/fileuploader.css','css/uniform.default.css',
'css/login_popup.css','css/validationEngine.jquery.css','css/ui-custom/jquery-ui.css'
],
dest: 'css/build/combined.css'
}
},
cssmin: {
css:{
src: 'css/build/combined.css',
dest: 'css/build/combined.min.css'
}
}
});
grunt.loadNpmTasks('grunt-contrib-concat');
grunt.loadNpmTasks('grunt-contrib-cssmin');
// Default task(s).
grunt.registerTask('default', ['cssmin']);
}
It will help me lot if you could provide some solution.
Thanks you

Your code is a bit different than the one at the grunt-contrib-cssmin documentation page.`
cssmin: {
options: {
shorthandCompacting: false,
roundingPrecision: -1
},
target: {
files: {
'output.css': ['foo.css', 'bar.css']
}
}
}
`

You have a problem with cssmin configuration.
Try to change for it:
cssmin: {
css:{
files: {
'css/build/combined.min.css': ['css/build/combined.css']
}
}
}
Maybe this fix your problem.
Hope it helps.
Regards.

It may be that you forgot to register the task:
grunt.registerTask('default', ['concat', 'cssmin']);

Running minified in Grunt cannot read property of undefined

I'm trying to build a Grunt task that minifys my JS files and return a single minified JS file.
This is my gruntfile.js file:
module.exports = function (grunt) {
// Project configuration.
grunt.initConfig({
minified: {
files: {
src: [
'js/*.js',
],
dest: 'js/min/'
},
options: {
allinone: true
}
},
});
grunt.loadNpmTasks('grunt-minified');
};
When I run the task it does work, but it also returns an error.
> cmd.exe /c grunt -b "C:\Users\alucardu\documents\visual studio 2015\Projects\JS-demo\JS-demo" --gruntfile "C:\Users\alucardu\documents\visual studio 2015\Projects\JS-demo\JS-demo\Gruntfile.js" minified
Running "minified:files" (minified) task
Warning: Cannot read property 'yellow' of undefined Use --force to continue.
Process terminated with code 3.
Aborted due to warnings.
I've done a search action in my entire solution for 'yellow' but it doesn't return any results. Also when I empty both my JS files that are being minified it still returns the error.
Does anyone know why it's returning this error?
By removing the
options: {
allinone: true
}
The warning no longer showed up, but it also doesn't concat the files together. So I've added another task called concat. So now my gruntfile looks like this:
module.exports = function (grunt) {
// Project configuration.
grunt.initConfig({
watch: {
scripts: {
files: ['js/*.js'],
tasks: ['concat', 'minified', 'uglify'],
},
},
concat: {
dist: {
src: ['js/*.js'],
dest: 'js/min/concat.js'
},
},
minified: {
files: {
src: ['js/min/concat.js'],
dest: 'js/min/minified.js'
},
},
uglify: {
my_target: {
files: {
'js/min/uglify.js': ['js/min/minified.jsconcat.js']
}
}
},
});
grunt.loadNpmTasks('grunt-contrib-watch');
grunt.loadNpmTasks('grunt-contrib-concat');
grunt.loadNpmTasks('grunt-minified');
grunt.loadNpmTasks('grunt-contrib-uglify');
};
And it seems to be working fine.

Compass can't find any sass files to compile after running grunt

I'm trying to run compass to compile my .scss files. I'm getting the following error:
Running "compass:dist" (compass) task
Compass can't find any Sass files to compile.
Is your compass configuration correct?.
If you're trying to start a new project, you have left off the directory argument.
Run "compass -h" to get help.
Running "watch" task
Waiting...
My .scss files are stored in /myproject/sass/ and /myproject/sass/bootstrap/
I'm expecting the .scss files to be compiled into a minified style.css file.
What do I need to do to sort this?
compass: {
dist: {
options: {
sassDir: 'sass',
cssDir: 'css'
}
}
},
watch: {
css: {
files: '**/*.scss',
tasks: ['compass']
}
}
});
grunt.loadNpmTasks('grunt-contrib-compass');
grunt.loadNpmTasks('grunt-contrib-watch');
grunt.loadNpmTasks('grunt-minified');
grunt.loadNpmTasks('grunt-contrib-concat');
grunt.loadNpmTasks('grunt-contrib-cssmin');
grunt.loadNpmTasks('grunt-contrib-uglify');
grunt.registerTask('default',['concat', 'minified', 'uglify', 'compass', 'watch']);
This might be worth trying:
watch: {
sass: {
files: '/sass/**/*.scss',
tasks: ['default']
},
},
I fixed it by adding this code:
compass: {
compile: {
options: {
cssDir: 'css'
}
}
},
This compiles the css (does not minify). I also changed a couple of other values for the files and directories so my grunt file now looks like this:
compass: {
dist: {
options: {
sassDir: ['sass/**/*.scss', 'sass/*.scss'],
cssDir: 'css/style.css'
}
}
},
compass: {
compile: {
options: {
cssDir: 'css'
}
}
},
watch: {
css: {
files: ['sass/style.scss'],
tasks: ['compass']
}
}

Grunt Watch isn't working anymore

I was trying to figure out why my JS wasn't being compiled by grunt, so I edited the gruntfile.js. And then grunt watch stopped. I've tried reverting the file with git and I've npm installed to try to see if that might help... does anyone see a problem with my gruntfile? Or perhaps have another possible solution?
module.exports = function(grunt){
grunt.loadNpmTasks('grunt-contrib-uglify');
grunt.loadNpmTasks('grunt-contrib-watch');
grunt.loadNpmTasks('grunt-contrib-compass');
grunt.initConfig({
uglify:{
my_target: {
files: {
'js/script.js': ['_/js/*.js']
}//files
}//target
},//uglify
compass:{
dev:{
options: {
config:'config.rb'
}//options
}//dev
}, //compass
watch: {
options:{ livereload: true },
scripts: {
files: ['_/js/*.js'],
tasks: ['uglify']
},
sass: {
files:['_/sass/*.scss'],
tasks: ['compass:dev']
}//sass
//scripts
// html: {
// files: ['*.html']
// } //for auto refresh browser, need script on html as well.
}//watch
})//initConfig
grunt.registerTask('default','watch') //run gunt and wait for changes
}//exports
and here are my package.json dependencies
"dependencies" : {
"grunt" : "~0.4.5",
"grunt-contrib-watch" : "~0.6.1",
"grunt-contrib-compass" : "~1.0.3",
"grunt-contrib-uglify" : "~0.9.1",
"matchdep" : "~0.3.0"
}

Grunt SCSS - Not reloading

I am trying to achieve a smooth workflow.
my problem:
My JS modifications are shown and minified and the live reload works fine. When I make changes to my SCSS files they do not run under the run command:
grunt
or the grunt plugin:
grunt watch
It only works when I invoke:
grunt sass
This was the output from the 'grunt sass' console window:
Macintosh:grunt-test Neil$ grunt sass
Running "sass:dist" (sass) task
File "css/global.css" created.
Done, without errors.
Notes:
When I run 'grunt watch' on a sass file I have noticed that grunt runs the minification on the javascript for no reason. Surely this be invoked when that file or one of its dependencies is effected?
Gruntfile.js Contents:
module.exports = function(grunt) {

grunt.initConfig({
pkg: grunt.file.readJSON('package.json'),

livereload: true

// 3. Where we tell Grunt we plan to use this plug-in.

// IMG CRUSH PLUGIN
grunt.loadNpmTasks('grunt-contrib-imagemin');
// GRUNT WATCH PLUGIN
grunt.loadNpmTasks('grunt-contrib-watch');
// SASS LIBARY PLUGIN
grunt.loadNpmTasks('grunt-contrib-sass');
// 4. Where we tell Grunt what to do when we type "grunt" into the terminal.
grunt.registerTask('default', ['sass','concat', 'uglify', 'imagemin', 'watch']);
};
I hope the above information helps. I have previously used Codekit, and it a really great app. I want to move to grunt but maybe my configuration file is incorrect I am close.
Any help would be greatly appreciated.

It looks like both of your issues occur within the watch configuration.
First, the reason the SASS task isn't working during watch is due to the files entry pointing to the wrong location. Your current files entry points to the "css" folder, but it should point to the "scss" folder, according to what you've specified in the actual "sass" task. In other words, your entry should be: files: ['scss/*.scss'].
css: {
files: ['scss/*.scss'],
tasks: ['sass'],
options: {
spawn: false,
}
}
Second, the JavaScript minification occurs during the watch whenever a SASS file changes because you have it listed here:
scripts: {
files: ['js/*.js', 'scss/*.scss'], // <-- scss is covered here
tasks: ['concat', 'uglify'],
options: {
spawn: false,
}
}
Change it to files: ['js/*.js'], instead to have the watch task kick in for JavaScript files only.
Once you address those issues, if things are slightly working you might want to expand the patterns so that it covers all files in the subdirectories for your JavaScript, CSS, SASS, etc. For example, js/*.js includes all .js files under the js folder, while js/**/*.js covers the js folder and its subfolders. You can read more under the GruntJS "globbing patterns" documentation.
EDIT: here's how the updated watch should look like...
watch: {
options: {
livereload: true
},
// css is really for Sass
css: {
files: ['scss/*.scss'],
tasks: ['sass'],
options: {
spawn: false,
}
},
// scripts will detect js changes
scripts: {
files: ['js/**/*.js'],
tasks: ['jshint', 'concat', 'uglify'],
options: {
spawn: false,
}
}
},
As mentioned, your individual tasks might need to use the ** pattern similar to what I've done with the "scripts" entry above: js/**/*.js

Compass watch with Grunt

I'd like to create a task to watch all my scss files. And I used "grunt-contrib-watch" and "grunt-contrib-sass" but it doesn't work.
My files and my directories : http://glui.me/?i=pz7vmwu9cfgbzt3/2013-11-28_at_12.46_2x.png/
My error :
MacBook-Pro-of-username:src username:src$ grunt
Running "cssmin:minify" (cssmin) task
File lib/stylesheets/bottom.min.css created.
Running "watch" task
Waiting...Bus error: 10
My grunt code :
module.exports = function(grunt){
grunt.initConfig({
pkg: grunt.file.readJSON('package.json'),
sass: {
dist: {
files: {
'lib/stylesheets/bottom.css' : 'lib/sass/bottom.scss'
}
}
},
watch: {
css: {
files: '**/*.scss',
tasks: ['sass']
}
},
cssmin: {
minify: {
files: [{
'lib/stylesheets/bottom.min.css': ['lib/stylesheets/bottom.css']
}]
}
}
});
grunt.loadNpmTasks('grunt-contrib-watch');
grunt.loadNpmTasks('grunt-contrib-sass');
grunt.registerTask('default', ['watch']);
}
There was an issue with node <= 0.10.20 and OSX mavericks. Upgrade node.js to the latest and it should fix the issue. See https://github.com/gruntjs/grunt-contrib-watch/issues/204
