运行环境:windows 8.1

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:\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
