Answer 1

试试这个
```
  from bs4 import BeautifulSoup    
```
适用于python3和BS 4以及

或许这会有所帮助：

 from bs4 import BeautifulSoup as bs
 import urllib
 url="http://example.com"
 soup = bs(urllib.urlopen(url))
 for link in soup.findAll('a'):
 print link.string

获取任何标签数据只需替换＆＃34; a＆＃34;带有你想要的标签

交叉检查文件名是否已命名＆＃34; bs4.py＆＃34;或者类似于＆＃34; HTMLParser.py＆＃34;

Answer 2

The reinstall failed..

由于pip install --upgrade --force-reinstall beautifulsoup4失败了。我猜你的系统中安装了多个版本的python，或者模块安装不正确。

您应该先尝试pip uninstall <module>卸载该模块，然后重新安装pip install <module>

导入beautifulsoup时出错
