初学Python，只会写简单的代码。手头有份Python代码，但是调用C模块生成?报错

报错内容如下：

Traceback (most recent call last):
  File "E:\Python27\setup.py", line 16, in <module>
    from setuptools import setup, find_packages
ImportError: No module named setuptools

我在调试之前，做了以下相关的安装：

[Cython](www.cython.org). Runtime requirements are the 
Python packages [numpy](www.numpy.org), [scipy](www.scipy.org),
[dateutil](https://labix.org/python-dateutil), [sqlalchemy](www.sqlalchemy.org), 
[sympy](http://sympy.org) and [jinja2](http://jinja.pocoo.org). The setup.py script described below
will pull these requirements automatically, but depending on your OS you might favor to install
them using your system's package manager.
Some of the decoder implementations require additional software, namely 
[GLPK](http://www.gnu.org/software/glpk/) (with C headers),
[IBM CPLEX](http://www.ibm.com/software/commerce/optimization/cplex-optimizer/), and
[Gurobi](http://gurobi.com). The first is open source, the others have free academic licenses
available.


We use the alternative gurobi python API called [gurobimh](https://github.com/supermihi/gurobimh).

有哪位大神指点，感激不尽！！
