使用ez_setup.py安装setuptools报错如下

Traceback (most recent call last):
  File "httpservice.py", line 5, in <module>
    import SimpleHTTPServer
  File "C:\Python27\lib\SimpleHTTPServer.py", line 27, in <module>
    class SimpleHTTPRequestHandler(BaseHTTPServer.BaseHTTPRequestHandler):
  File "C:\Python27\lib\SimpleHTTPServer.py", line 208, in SimpleHTTPRequestHandler
    mimetypes.init() # try to read system mime.types
  File "C:\Python27\lib\mimetypes.py", line 358, in init
    db.read_windows_registry()

    for subkeyname in enum_types(hkcr):

    ctype = ctype.encode(default_encoding) # omit in 3.x!
UnicodeDecodeError: 'ascii' codec can't decode byte 0xb0 in position 1: ordinal not in range(128)

解决方法：

通过分析最后的错误提示，是由于setuptools包中的setup.py编码格式错误，导致无法安装，以上虽然报错，但是setuptools-5.5.zip已经下载完成。那么就可以通过手工安装setuptools包：

1、解压setuptools-5.5.zip至C:\Python27\Lib\site-packages\setuptools-5.5 

2、修改setup.py，在代码中添加如下几句即可：

修改默认的编码方式

import sys

reload(sys) 

sys.setdefaultencoding('gb18030') 

3、在cmd窗口中进入Python27\Lib\site-packages\setuptools-5.5目录，然后输入：python setup.py install，即可安装成功
