準備工作

1.安裝python
2.安裝numpy
3.設定python環境變數，系統環境變數PATH後新增C:\Python27;C:\Python27\Scripts

安裝setuptools

使用ez_setup.py自動安裝，將此頁末尾程式碼儲存為“ez_setup.py”檔案，雙擊自動完成安裝。執行easy_install命令，出現下面結果，表示正確安裝，出現問題的話，關閉當前開啟的CMD視窗，重新開啟再輸入命令。

C:\Users\Admin>easy_install
error: No urls, filenames, or requirements specified (see --help)
 

解決使用Matplotlib遇到的問題

問題：

>>> import matplotlib
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "C:\Python27\lib\site-packages\matplotlib\__init__.py", line 110, in <mod
ule>
    raise ImportError("matplotlib requires dateutil")
ImportError: matplotlib requires dateutil
 

解決方法，使用已經安裝的setuptools，執行easy_install命令，安裝python-dateutil和pyparsing：

C:\Users\Admin>easy_install python-dateutil
C:\Users\Admin>easy_install pyparsing

ez_setup.py的程式碼：

#!python
"""Bootstrap setuptools installation

If you want to use setuptools in your package's setup.py, just include this
file in the same directory with it, and add this to the top of your setup.py::

    from ez_setup import use_setuptools
    use_setuptools()

If you want to require a specific version of setuptools, set a download
mirror, or use an alternate download directory, you can do so by supplying
the appropriate options to ``use_setuptools()``.

This file can also be run as a script to install or upgrade setuptools.
