Grunt is not defined

问题

Just Getting started with grunt, and when I run grunt I get this error

Loading "Gruntfile.js" tasks...ERROR
>> ReferenceError: grunt is not defined

This is my Gruntfile.js

module.exports = function(grunt){
  'use strict';
};

I had it suddenly happen to me,

'use strict';
module.exports = function(grunt) {
  grunt.initConfig({
    sass: {
      dist: {
        files: {
          'style.css': 'style.scss'
        },
        options: {
          includePaths: ['css/'],
          outputStyle: 'nested'
        }
      }
    },
  });
  grunt.loadNpmTasks('grunt-sass');
  grunt.registerTask('sass', ['sass']);

};

Make sure the loadNpmTasks and registerTask commands are inside the module.export, if they're outside of the scope of that closure grunt won't be defined, so it fails

Not entirely sure why, but this resolved that issue:

'use strict';
module.exports = function(grunt){
};

回答3:

I too saw many "grunt not defined" error messages on my terminal.

I grabbed another gruntfile.js from the same directory where I had Node and NPM installed, and replaced the boilerplate gruntfile.js with the other gruntfile.js.

Now, I call Grunt and it works.

I had trailing commas in my gruntfile code which was throwing that error. Thank you ReSharper. Hope this helps someone.

   pkg: grunt.file.readJSON('package.json'),
    ngAnnotate: {
        options: {
            singleQuotes: true
        },
        FFApp: {
            files: {
                'Scripts/Angular-Annotated/Annotated.js': ['Scripts/Angular/**/*js']
            }
