bower failes for dependency "angular-ui-grid": "^3.2.9"

[mindej]

I get this error:

bower cached https://github.com/angular-ui/bower-ui-grid.git#3.2.9
bower validate 3.2.9 against https://github.com/angular-ui/bower-ui-grid.git#^3.2.9
bower cached https://github.com/angular/bower-angular.git#1.4.12
bower validate 1.4.12 against https://github.com/angular/bower-angular.git#>=1.2.16 1.4.x
bower install angular-ui-grid#3.2.9
bower install angular#1.4.12
>> Installed bower packages
Fatal error: ENOENT: no such file or directory, stat 'app/lib/angular-ui-grid/less'

to reproduce use bower.json:

{
  "name": "app",
  "version": "0.0.1",
  "dependencies": {
    "angular-ui-grid": "^3.2.9"
  },
  "analytics": false
}

Can you share your gruntfile please?

Here it is:

  bower: {
            install: {
                options: {
                    targetDir: 'app/lib',
//                    layout: 'byType',
                    install: true,
                    verbose: true,
                    cleanTargetDir: true,
                    cleanBowerDir: true,
                    bowerOptions: {}
                  }
            }
          }
