grunt –version

grunt-cli v0.1.8
grunt v0.4.1

$ npm -v

1.2.18

$ node -v

v0.10.6

and when i do grunt init, to create the Gruntfile.js i get error:

$ grunt init 
A valid Gruntfile could not be found. Please see the getting started guide for
more information on how to configure grunt: http://gruntjs.com/getting-started
Fatal error: Unable to find Gruntfile.

I have searched for Grunfile.js, i get:

/home/ka/.npm/grunt-cli/0.1.8/package/Gruntfile.js
/home/ka/tmp/npm-1464/1368671910572-0.38816986070014536/package/Gruntfile.js

/root/.npm/grunt/0.4.1/package/Gruntfile.js
/root/.npm/grunt-cli/0.1.8/package/Gruntfile.js

Can i just copy one of these grunt files, to /ex/co/www/dev/htdocs/unittest ( where the javascipt / quint test are ) ? or is there something else i am missing

i am trying to run grunt on Centos 6.4

and why does’nt grunt init creates the Gruntfile.js ?

cp /root/.npm/grunt/0.4.1/package/Gruntfile.js /ex/co/www/dev/htdocs/unittest/

ok copied it AS-IS and now getting better errors:

I think what you’re looking for is the actual command line tool grunt-init found in the Project Scaffolding documentation.

Your current command grunt init is looking for a Gruntfile.js and the task init inside it. It is obviously unable to find your Gruntfile.js so is throwing that error.

Edit:

Your new error is because you have copied a Gruntfile.js file over and the default task (found near the bottom if you want to open it) will be calling those modules. Normally you will have used something like bower to install them into your local directory.

Your default task I referred to above will look something like this:
```
grunt.registerTask('default', ['jshint', 'qunit', 'concat', 'uglify']);
```
This is basically saying: when I run grunt at the command line, run the tasks jshint, qunit, concat and uglify in that order. These tasks will have been specified earlier on in the Gruntfile. To understand the file more check out a sample Gruntfile.

May I suggest taking a look at the Yeoman as it is a great tool to provide you with scaffolding for your apps (including a working Gruntfile.js).

Edit 2:

It is important you understand what is happening. The Gruntfile.js you have copied over looks to be calling “subgrunt” tasks. i.e. grunt tasks in sub projects. Is this what you are wanting?

Following through your Gruntfile.js – when you run grunt it is calling the following order: 'jshint', 'nodeunit', 'subgrunt'.

Ideally you want to write this yourself rather than copying it as there are some options being called by jshint I am unfamiliar with. If you read the jshint documentation it doesn’t mention the first three options.

I think you should try something like this:
```
jshint: {
  options: {
    curly: true,
    eqeqeq: true,
    immed: true,
    latedef: true,
    newcap: true,
    noarg: true,
    sub: true,
    undef: true,
    unused: true,
    boss: true,
    eqnull: true,
    node: true,
    es5: true
  }
  files: {
    src: ['path/to/your/*.js', 'another/path/to/your/*.js']
  }
}
```
You should read through the documentation for each task and make sure you understand the options you are passing through.

Another hint. If you see a file reference like the following:
```
 
```
This is a reference to a particular file/property set in the Gruntfile.js. In this case, this came from the watch task and points to the jshint.gruntfile property as a file to watch.
