установить Rpy2 на Mac получил ошибку

Question

Я пытаюсь установить Rpy2 на mac Yosemite. Я прочитал все сообщения разных людей о том, как установить этот пакет. Никто не был полезен для меня, так как моя проблема специфична

я первый сделал

sudo easy_install pip 

Тогда я сделал

pip install rpy2 

Но я получил что-то вроде

Я попытался запустить с

easy_install rpy2 

Тогда я получил некоторые ошибки

error: can't create or remove files in install directory 

The following error occurred while trying to add or remove files in the 
installation directory: 

    [Errno 13] Permission denied: '/Library/Python/2.7/site-packages/test-easy-install-1490.pth' 

The installation directory you specified (via --install-dir, --prefix, or 
the distutils default setting) was: 

    /Library/Python/2.7/site-packages/ 

Perhaps your account does not have write access to this directory? If the 
installation directory is a system-owned directory, you may need to sign in 
as the administrator or "root" account. If you do not have administrative 
access to this machine, you may wish to choose a different installation 
directory, preferably one that is listed in your PYTHONPATH environment 
variable. 

For information on other options, you may wish to consult the 
documentation at: 

    https://pythonhosted.org/setuptools/easy_install.html 

Please make the appropriate changes for your system and try again. 

Finlly Я сделал это по-другому, и она работала, по-видимому

sudo easy_install rpy2

Для проверки установленных пакетов использования:

1 - в оболочке Python/введите команду help('modules')

2 - Команда pip list
