why can't install setuptools in debian7?

I want to install setuptools according to the web. https://pypi.python.org/pypi/setuptools/#unix-wget In my vps console: root@online:~# python3 Python 3.4.0 (default, Oct 22 2014, 09:59:53) [GCC 4.7.2] on linux Type “help”, “copyright”, “credits” or “license” for more information.

exit()
