Как удалить эту ошибку при установке numpy на Ubuntu?

Я получаю это исключение при попытке установить numpy. Я попробовал обоих путем прямого вызова зернышка (команда: победите устанавливают numpy), и через sudo также. Помогите разрешить это:

    fareha@fareha-Inspiron-5537:~$ sudo pip install numpy scipy
    [sudo] password for fareha: 
    The directory '/home/fareha/.cache/pip/http' or its parent directory  is not owned by the current user and the cache has been disabled. Please check the permissions and owner of that directory. If executing pip with sudo, you may want sudo's -H flag.
