Fatal error: options argument must be an object

[atav32]

module.exports = function(grunt) {
  grunt.loadNpmTasks('grunt-bower-task');

  grunt.initConfig({
    bower: {
      install: {
        options: {
        }
      }
    }
  });
};

same here:

Running "bower:install" (bower) task
Fatal error: options argument must be an object

 bower: {
            install: {
                options: {
                    copy: false
                }
            }
        },

You should check the bower version in your package.json, so it looks like this:

"grunt-bower-task": "~0.4.0"
