laravel用了分组的权限认证后，路由里的name值全部失效

Route::get('admins/account/login','admins\Account@login')->name('login');
Route::get('admins/account/captcha','admins\Account@captcha')->name('captcha');
Route::post('admins/account/dologin','admins\Account@dologin')->name('dologin');


Route::namespace('admins')->middleware(['auth','rights'])->group(function (){
    Route::get('admins/account/captcha','Home@index')->mame('index');
});

用了分组后带有name值的路由全部失效，咋办啊，route（'index'）和外面相关的均无法使用Copy
