from bs4 import BeautifulSoup 报错

导入BeautifulSoup，出现下面错误：

Python 2.7.14 (default, Sep 17 2017, 18:50:44)

Type "help", "copyright", "credits" or "license" for more information.
>>> from bs4 import BeautifulSoup
Traceback (most recent call last):

百度半天，都是说bs4写错的，还好看到个大佬解决了问题：http://blog.csdn.net/codechelle/article/details/56292200

解决方法：就如博客大佬说的，改个名字，将 base.py 改为 _base.py，将 base.pyc 改为 _base.pyc 即可。

                  路径一般是一样的，照抄即可。
