Solve the following python programming problem given the following code:
def setUp(self) : 
    super (TestCli, self).setUp () 
    self.do_alembic_cmd_p = mock.patch.object (cli, 'do_alembic_command') 
    self.do_alembic_cmd = self.do_alembic_cmd_p.start () 
    self.mock_alembic_err = mock.patch ('alembic.util.err').start () 
    self.mock_alembic_warn = mock.patch ('alembic.util.warn').start () 
    self.mock_alembic_err.side_effect = SystemExit 
    def mocked_root_dir(cfg) : 
        return os.path.join ('/fake/dir', cli._get_project_base (cfg)) 
mock_root = mock.patch.object (cli, '_get_package_root_dir').start () 
    mock_root.side_effect = mocked_root_dir 
    mock.patch ('neutron.common.utils.ensure_dir').start () 
    self.configs = [] 
    self.projects = ('neutron', 'networking-foo', 'neutron-fwaas') 
    ini = os.path.join (os.path.dirname (cli.__file__), 'alembic.ini') 
    self.useFixture (MigrationEntrypointsMemento ()) 
    cli.migration_entrypoints = { 
        
} 
    for project in self.projects : 
        config = alembic_config.Config (ini) 
        config.set_main_option ('neutron_project', project) 
        module_name = (project.replace ('-', '_') + '.db.migration') 
        attrs = ('alembic_migrations',) 
        script_location = ':'.join ([project, attrs [0]]) 
        config.set_main_option ('script_location', script_location) 
        self.configs.append (config) 
        entrypoint = pkg_resources.EntryPoint (project, module_name, attrs = attrs) 
        cli.migration_entrypoints [project] = entrypoint 

    
    

    Fix the buggy line: script_location = ':'.join ([project, attrs [0]])
