У меня установлен XCode, а также FreeTDS. Я попытался подключиться к моему SQL Server, и он отлично работает.

Теперь мне нужно разработать приложение на python, которое работает с этим SQL Server, и я пытаюсь установить pymsql, но я получил эту ошибку при запуске команды sudo python setup.py:

==> sudo python setup.py install
