Trouble configuring grunt bower-install

Question

I am quite new to the Yeoman workflow(started using Yeoman today). I am trying to install grunt bower-install, in order to automate the asset management process.

The problem is that despite the fact I followed the the instructions in the docs to the last of them, when trying to run grunt bower-install I get errors.

When trying to run this command from the home DIR, the errors are as following:

oleg@ob:~$ !!
Running "bower-install:app" (bower-install) task
Verifying property bower-install.app.src exists in config...ERROR
>> Unable to process task.
Warning: Required config property "bower-install.app.src" missing. Use --force to continue.

Aborted due to warnings.

Total 12ms

After cding into the app directory and running the command again, I get a different error:

oleg@ob:~/app$ grunt bower-install
Loading "gruntfile.js" tasks...ERROR
>> Error: Unable to read "package.json" file (Error code: ENOENT).
Warning: Task "bower-install" not found. Use --force to continue.

Aborted due to warnings.

Any help is much more then greatly appreciated!

My Gruntfile.js (within app/ dir) looks as following:

'use strict';

module.exports = function (grunt) {
    // Project configuration
    grunt.initConfig({
        // Metadata
        pkg: grunt.file.readJSON('package.json'),
        banner: '/*! <%= pkg.name %> - v<%= pkg.version %> - ' +
            '<%= grunt.template.today("yyyy-mm-dd") %>\n' +
            '<%= pkg.homepage ? "* " + pkg.homepage + "\\n" : "" %>' +
            '* Copyright (c) <%= grunt.template.today("yyyy") %> <%= pkg.author.name %>;' +
            ' Licensed <%= props.license %> */\n',
        // Task configuration
        concat: {
            options: {
                banner: '<%= banner %>',
                stripBanners: true
            },
            dist: {
                src: ['lib/<%= pkg.name %>.js'],
                dest: 'dist/<%= pkg.name %>.js'
            }
        },
        uglify: {
            options: {
                banner: '<%= banner %>'
            },
            dist: {
                src: '<%= concat.dist.dest %>',
                dest: 'dist/<%= pkg.name %>.min.js'
            }
        },

                tasks: ['jshint:lib_test', 'qunit']
            }
        }
    });

    // These plugins provide necessary tasks
    grunt.loadNpmTasks('grunt-contrib-concat');

    // Default task
    grunt.registerTask('default', ['jshint', 'qunit', 'concat', 'uglify']);
};

You're right to run grunt commands from the root directory of your project. However, I believe you're running the wrong grunt-bower-install subtask, judging from this error:

Running "bower-install:app" (bower-install) task
Verifying property bower-install.app.src exists in config...ERROR
>> Unable to process task.
Warning: Required config property "bower-install.app.src" missing.

If you simply run grunt bower-install, it should work. Either that, or rename

'bower-install': {
    target: { /* ... */ }
}

to...

'bower-install': {
    app: { /* ... */ }
}
