Window下python 2.73安装pip

(1)安装pip到官网下载.gz文件，解压后在其目录下执行cmd

 命令：pyhton setup.py install

安装完成后将pip.exe所在的目录添加到系统路径便于调用

发现【ImportError: No module named setuptools】提示先要安装setuotools

(2)使用https://bootstrap.pypa.io/ez_setup.py脚本(新建一个txt将所有内容拷贝下来改名为ez setup.py)安装setuptools  命令：pyhton ez setup.py install

可能遇到的错误【UnicodeDecodeError: 'ascii' codec can't decode byte 0xd3 in position 9: ordinal not in range(128)】

说明：这里有很多方法，例如在lib/mimify.py进行处理，但后来试了不行，采用下面的方法可行

解决方法：在python/lib/site.py中加入  （若有import sys ,则该句省略）

import sys
reload(sys)
sys.setdefaultencoding('gbk')

原因：

Unicode Default Encoding

    The Unicode implementation has to make some assumption about the    encoding of 8-bit strings passed to it for coercion and about the    encoding to as default for conversion of Unicode to strings when    no specific encoding is given.  This encoding is called <default    encoding> throughout this text.    For this, the implementation maintains a global which can be set    in the site.py Python startup script.  Subsequent changes are not    possible.  The <default encoding> can be set and queried using the    two sys module APIs:      sys.setdefaultencoding(encoding)        --> Sets the <default encoding> used by the Unicode implementation.            encoding has to be an encoding which is supported by the            Python installation, otherwise, a LookupError is raised.            Note: This API is only available in site.py!  It is            removed from the sys module by site.py after usage.      sys.getdefaultencoding()        --> Returns the current <default encoding>.    If not otherwise defined or set, the <default encoding> defaults    to 'ascii'.  This encoding is also the startup default of Python    (and in effect before site.py is executed).    Note that the default site.py startup module contains disabled    optional code which can set the <default encoding> according to    the encoding defined by the current locale.  The locale module is    used to extract the encoding from the locale default settings    defined by the OS environment (see locale.py).  If the encoding    cannot be determined, is unknown or unsupported, the code defaults    to setting the <default encoding> to 'ascii'.  To enable this    code, edit the site.py file or place the appropriate code into the    sitecustomize.py module of your Python installation.
