Task "default" not found. Use --force to continue. Aborted due to warnings

here is my gruntfile.js

var fs = require("fs"),
    browserify = require("browserify"),
    pkg = require("./package.json");

module.exports = function(grunt) {
  grunt.initConfig({
    mochaTest: {
      test: {
        options: {
          style: 'bdd',
          reporter: 'spec'
        },
        src: ['test/unit/*.js']
      }
    },
    pkg: grunt.file.readJSON('package.json'),
    uglify: {
      options: {
        banner: "/*\n" + grunt.file.read('LICENSE') + "*/"
      },
      dist: {
        files: {
          '<%=pkg.name%>-<%=pkg.version%>.min.js': ['<%=pkg.name%>-<%=pkg.version%>.js']
        }
      }
    }
  });

  grunt.registerTask('build', 'build a browser file', function() {
    var done = this.async();

    var outfile = './brain-' + pkg.version + '.js';

    var bundle = browserify('./browser.js').bundle(function(err, src) {
      console.log("> " + outfile);

      // prepend license
      var license = fs.readFileSync("./LICENSE");
      src = "/*\n" + license + "*/" + src;

      // write out the browser file
      fs.writeFileSync(outfile, src);
      done();
    });
  });
  grunt.registerTask('test', 'mochaTest');

  grunt.loadNpmTasks('grunt-mocha-test');
  grunt.loadNpmTasks('grunt-contrib-uglify');
};

When I simply run grunt in the terminal - here is the error

Warning: Task "default" not found. Use --force to continue. Aborted due to warnings.

After adding --force it shows:

Warning: Task "default" not found. Used --force, continuing. Done, but with warnings.

You forgot to add default task.

add following line after "grunt.registerTask('test', 'mochaTest');" line.

grunt.registerTask('default', ['test', 'build']);

this task will run both 'test' and 'build'. when run "grunt" without any argument.

For more details refer grunt document on task.

Tasks have to be registered in grunt before they can be executed.

You have registered a build task in your grunt,

grunt.registerTask('build', 'build a browser file', function() {
    var done = this.async();

    var outfile = './brain-' + pkg.version + '.js';

    var bundle = browserify('./browser.js').bundle(function(err, src) {
      console.log("> " + outfile);

      // prepend license
      var license = fs.readFileSync("./LICENSE");
      src = "/*\n" + license + "*/" + src;

      // write out the browser file
      fs.writeFileSync(outfile, src);
      done();
    });
  });

This can be executed by called grunt build.

When you execute grunt, by default, it looks for a task called default, which should be registered.

So, register a default task (same like build task)

grunt.registerTask('default', 'Executed default task', function() {
    ...
});

You can also pass the third parameter as array of registered tasks so that that will be executed if you run grunt.

grunt.registerTask('default', 'Executed default task', [
    'task1',
    'task4',
    'task3',
]);

Now when you execute grunt, all these tasks will be executed in sequence.

Please note that the each task in the tasks array should be registered using grunt.registerTask.

There is no task called "default" in your gruntfile. Are you trying to run the build task ?

If so, replace this line:

grunt.registerTask('build', 'build a browser file', function() { ...

With this line

grunt.registerTask('default', 'build a browser file', function() { ...

First you need to understand how grunt command work

  1. you define/register a task in your Gruntfile.js
  2. Thenyou call that task from the command prompt

From your grunt file below is a task registered

 grunt.registerTask('build', 'build a browser file', function() {
    var done = this.async();

    var outfile = './brain-' + pkg.version + '.js';

    var bundle = browserify('./browser.js').bundle(function(err, src) {
      console.log("> " + outfile);

      // prepend license
      var license = fs.readFileSync("./LICENSE");
      src = "/*\n" + license + "*/" + src;

      // write out the browser file
      fs.writeFileSync(outfile, src);
      done();
    });
  });

you can then call that task by calling grunt build which will run that task. And when you only run grunt it looks for a task which name is default

As in your grunt file there is no default task defined you command fails.
