Windows8下安装Python的BeautifulSoup

运行环境：Windows 8.1
Python：2.7.6

在安装的时候，我使用的pip来进行安装,命令如下：

pip install beautifulsoup4

运行的时候，报错如下：

Exception:

Storing debug log for failure in C:\Users\Administrator\pip\pip.log

解决方法：打开C:\Python27\Lib下的 mimetypes.py 文件，找到大概256行的

default_encoding = sys.getdefaultencoding()

改成：

if sys.getdefaultencoding() != 'gbk':

    reload(sys)

    sys.setdefaultencoding('gbk')

default_encoding = sys.getdefaultencoding()

安装成功后，验证是否安装成功：

C:\Users\Administrator>python

Python 2.7.6 (default, Nov 10 2013, 19:24:24) [MSC v.1500 64 bit (AMD64)] on 32

>>> from bs4 import BeautifulSoup

>>> exit()

如果“from bs4 import BeautifulSoup”没有报错的话，则说明安装成功，否则，将报类似错误如下：

Traceback (most recent call last):

  File "<stdin>", line 1, in <module>

ImportError: No module named bs4
