I have installed Grunt like so `npm install -g grunt-cli successfully.
I have also installed the grunt-contrib-concat libary succesfully like so: npm install grunt-contrib-concat --save-dev
I have created a package.json:
{
"name": "my-project-name",
"version": "0.1.0",
"devDependencies": {
"grunt": "~0.4.1",
"grunt-contrib-jshint": "~0.1.1",
"grunt-contrib-nodeunit": "~0.1.2"
}
}
and a Gruntfile.js:
module.exports = function(grunt) {
grunt.initConfig({
pkg: grunt.file.readJSON('package.json'),
concat: {
options: {
separator: ';'
},
dist: {
src: ['src/init.js', 'src/Game.js', 'ui/Ui.js', 'ui/AddBTS.js', 'ui/Toolbar.js'],
dest: 'built.js'
}
}
});
grunt.loadNpmTasks('grunt-contrib-concat');
};
Now when I run grunt concat I get the following error:
Fatal error: Unable to find local grunt.
If you're seeing this message, either a Gruntfile wasn't found or grunt
hasn't been installed locally to your project. For more information about
installing and configuring grunt, please see the Getting Started guide:
This is my first time using Grunt and I've been trying to solve this problem for over 2 hours now. Please could someone help me and advise what I've not set up correctly.
Thanks in advance!
It's likely that Grunt is not installed locally in your project folder (which is different than grunt-cli). You have it in your package.json so try doing npm install or alternately npm install grunt.
For more information see the getting started page:
Note that installing grunt-cli does not install the grunt task runner! The job of the grunt CLI is simple: run the version of grunt which has been installed next to a Gruntfile. This allows multiple versions of grunt to be installed on the same machine simultaneously.

I'm new to use grunt, I just create a real sample to run. But I get blocked my A warning Warning: Task "default" not found
I just copied sample from http://gruntjs.com/getting-started
My package is
{
"name": "my-project-name",
"version": "0.1.0",
"devDependencies": {
"grunt": "~0.4.5",
"grunt-contrib-jshint": "~0.10.0",
"grunt-contrib-nodeunit": "~0.4.1",
"grunt-contrib-uglify": "~0.5.0"
}
}
my Gruntfile.js is
module.exports = function(grunt) {
grunt.registerTask('default', 'Log some stuff.', function() {
grunt.log.write('Logging some stuff...').ok();
});
};
it just print some simple log, why it doesn't work?
Copying the pasting the code from the grunt page won't do anything by itself. Did you first install grunt by console: npm install -g grunt-cli ?
Grunt is a task runner; that is, it does not have the ability to do the task itself, but starts the program listed in the gruntfile, runs the program on the noted files or folders, and stops each task before going on to the next.
You'll need to make sure that the JSHint program has been installed on your system before running grunt, or grunt won't run that task. You'll enter this in your console to install it: npm install grunt-contrib-jshint --save-dev
Grunt doesn't know what files to run JSHint on, so you'll need to tell it where to look. To do that, you'll need to carefully read the grunt-contrib-jshint page in the npm plugins site at http://gruntjs.com/plugins.
In addition, JSHint has these options: http://jshint.com/docs/options/ You'll need to learn the correct syntax to put them in the gruntfile.
Grant makes repetitive tasks simpler, but you'll still need to do a bit of homework to put all the different pieces together to get it working for you.
I wrote a complete article on getting started in grunt, based on my own learning: https://iphonedevlog.wordpress.com/2016/10/31/how-to-use-grunt-to-automate-repetitive-tasks/
I made a folder g in root(C:/) in where I try to install Grunt via npm.
I sucessfull made: npm install -g grunt-cli.
I configured package.json to this:
{
"name": "testing",
"version": "0.0.0",
"dependencies": {
"grunt": "~0.4.5" },
"description": "testing",
"main": "index.html",
"scripts": {
"test": "echo \"Error: no test specified\" && exit 1"
},
"author": "",
"license": "ISC",
"devDependencies": {
"grunt": "^0.4.5"
}
}
So good so far.
BUT: When I try to install Grunt: npm install grunt --save-dev and modules(plugins) then I run into this error: npm WARN package.json testing#0.0.0 No repository field...
I use GitHub where I've forked Grunt and Grunticon.
Then I can't succed with nothing towards installing Grunt...
Any good clues and help in solving this?
Okay, I think I see the problem clearly now. Here are some instructions for getting Grunt running, try to follow these exactly, do not create any other folders as it could cause issues for Grunt or Node.
Create a folder for your project, this can be anywhere on your system.
Save the file you have above as package.json in that folder.
Now install the global Grunt CLI
~$ npm install -g grunt-cli <-- Note this is "grunt-cli" NOT "grunt"
Then go to the new directory you created and run this command:
~/new-directoty$ npm install
This will install the Grunt runtime locally for your project because it is specified in package.json
Create a very simple config file in the new directory and name it Gruntfile.js:
module.exports = function(grunt) {
grunt.initConfig({ /* your config will go in here */ });
/* multi-task definitions go here */
};
Now try to run Grunt just to test that it works:
~/new-directory$ grunt
After that you are ready to start adding plugins, but that's a bigger topic. Good luck.
I trying to use grunt-contrib-sass and receive an error:
You need to have Ruby and Sass installed and in your PATH for this task to work.
But i'm sure that i already install Ruby and Sass.
I have check it with below command
ruby -v and receive 1.9.3p545
sass -v and receive 3.4.5
So that make me sure i already install Ruby and Sass.
But when i use
grunt sass
I receive that error.
Please help me and i really appreciate it.
Sorry my English is not so good.
This is my package.json
{
"name": "TEST",
"version": "0.0.1",
"dependencies":
{
"grunt": "~0.4.5",
"grunt-contrib-sass": "~0.8.1"
}
}
and this is gruntfile.js
module.exports = function(grunt)
{
grunt.loadNpmTasks('grunt-contrib-sass');
grunt.initConfig
({
sass:
{
dist:
{
options:
{
style: 'compressed'
},//options
files:
{
'css/style.css': 'component/sass/style.scss'
}//files
}//dist
}//sass
})//initConfig
}//exports
Run gem install sass and everything should be fine. Because a fresh install fixes the installation paths and bindings.
I'm trying to setup gruntJS on my local machine. These are the steps I have already done:
Install nodeJS
Download gruntJS in a root folder of project with command:
npm install -g grunt-cli
Download grunt also in a root folder of project with:
npm install grunt
Also, I have created Gruntfile.js and here is content of it:
module.exports = function(grunt) {
// Project configuration.
grunt.initConfig({
min: {
css: {
src: 'templates/folder1/css/*.css',
dest: 'app.min.css'
}
},
});
};
And I was expected how this will work and minimize all css files and move it to the root ( because destination specified as root ).
I need to say how I was follow this tutorial:
https://www.youtube.com/watch?v=q3Sqljpr-Vc
And I really don't know what I do wrong.
Here is how I call grunt and error ( its better to say warning message ) which I get:
C:\wamp\www\myProject>grunt min
Warning: Task "min" not found. Use --force to continue.
Aborted due to warnings.
you need to install some tasks for use. From your example i would guess you are trying to minify some CSS?
For that i would use the grunt-contrib-cssmin task. To use first install using
npm install grunt-contrib-cssmin
you will also need to register the task at the bottom of your gruntfile like this grunt.loadNpmTasks('grunt-contrib-cssmin').
then your gruntfile will look like this
module.exports = function(grunt) {
// Project configuration.
grunt.initConfig({
cssmin: {
minify: {
src: ['templates/folder1/css/*.css'],
dest: 'app.min.css'
}
}
});
grunt.loadNpmTasks('grunt-contrib-cssmin');
grunt.registerTask('min' ['cssmin']);
};
For more info i recommend you read the documentation and familiarise yourself with the examples at http://gruntjs.com/sample-gruntfile
I used the following as pre-build event in Visual Studio 2013 to compile Bootstrap 3.0 with recess according to this answer and it worked
recess "$(ProjectDir)Content\bootstrap\bootstrap.less" --compress > "$(ProjectDir)Content\bootstrap-compiled.css"
Now this doesn't work for Bootstrap 3.1.1 and they say Grunt will do it. I've tried:
grunt-contrib-less "$(ProjectDir)Content\bootstrap\bootstrap.less" --compress > "$(ProjectDir)Content\bootstrap-compiled.css"
But can't get it to work. Any ideas how to get Grunt to work with VS 2013.
Note: I've Installed Node.js and recess earlier, then > npm install grunt-contrib-less then to be sure >npm update grunt-contrib-less.
I've got this working in a slightly different way:
Ensure you've got grunt-cli installed globally (npm install -g grunt-cli)
Create a Gruntfile.js in your project or solution, and define a target to do whatever less compiling you want (e.g. less)
Add call grunt less to your pre-build event (if you don't specify CALL, then the process doesn't return after grunt)
You can add different targets to the development and production build processes if you like. You can also set up more targets for other tasks - I have one so I can run grunt watch to automatically recompile my CSS if I edit less files.
Step-by-step guide to converting the VS2013 sample project to use less and Grunt:
Remove bootstrap and install bootstrap less:
Uninstall-Package bootstrap
Install-Package Twitter.Bootstrap.less
Open a command prompt and cd to your project directory
Ensure grunt-cli is installed globally:
npm install -g grunt-cli
Create a package.json file:
npm init
Install grunt and grunt-contrib-less locally:
npm install grunt grunt-contrib-less`
Create a file in your project called Gruntfile.js with the following contents:
module.exports = function (grunt) {
grunt.initConfig({
pkg: grunt.file.readJSON('package.json'),
less: {
dev: {
options: {
sourceMap: true,
dumpLineNumbers: 'comments',
relativeUrls: true
},
files: {
'Content/bootstrap.debug.css': 'Content/bootstrap/bootstrap.less',
}
},
production: {
options: {
cleancss: true,
compress: true,
relativeUrls: true
},
files: {
'Content/bootstrap.css': 'Content/bootstrap/bootstrap.less',
}
}
},
});
grunt.loadNpmTasks('grunt-contrib-less');
// Default task(s).
grunt.registerTask('default', ['less']);
grunt.registerTask('production', ['less:production']);
grunt.registerTask('dev', ['less:dev']);
};
Edit your Visual Studio pre-build event to include:
cd $(ProjectDir)
call grunt --no-color
(--no-color removes some of the control characters from the Visual Studio build output)
Build your project, then enable show all files, and incldue the two compiled css files in your project (so that web deploy picks them up).
