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：
复制代码 代码如下:
pip install beautifulsoup4
运行的时候，报错如下：
复制代码 代码如下:

Storing debug log for failure in C:UsersAdministratorpippip.log
解决方法：打开C:Python27Lib下的 mimetypes.py 文件，找到大概256行的
复制代码 代码如下:
default_encoding = sys.getdefaultencoding()
改成：
复制代码 代码如下:
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：
复制代码 代码如下:
C:UsersAdministrator>python
Python 2.7.6 (default,Nov 10 2013,19:24:24) [MSC v.1500 64 bit (AMD64)] on 32
Type "help","copyright","credits" or "license" for more information.
>>> 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：
复制代码 代码如下:
Traceback (most recent call last):
File "<stdin>",line 1,in <module>
ImportError: No module named bs4
