复制代码 代码如下:

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

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:\Users\Administrator>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
