title: Install BeautifulSoup on python3.5, Mac , ImportError:No module named 'bs4'
body: <p>I want to install BeautifulSoup, I use python3.5  on Mac<br>
  I have tried many methods:<br>
  I try to download <code>beautifulsoup4-4.4.1.tar.gz</code> from official website,and in terminal type:</p>
  
  <blockquote>
    <p>$ cd [my path]</p>
    
    <p>$ sudo python3.5 ./setup.py install</p>
  </blockquote>
  
  <p>I also tried:</p>
  
  <blockquote>
    <p>$ sudo pip3 install beautifulsoup4  </p>
  </blockquote>
  
  <p>and the terminal says:</p>
  
  <blockquote>
    <p>Requirement already satisfied (use --upgrade to upgrade): beautifulsoup4 in /Library/Frameworks/Python.framework/Versions/3.5/lib/python3.5/site-packages/beautifulsoup4-4.4.1-py3.5.egg</p>
  </blockquote>
  
  <p>So I think it is already installed,
  but when In python3 I type (I use pycharm)</p>
  
  <blockquote>
    <p>from bs4 import BeautifulSoup</p>
  </blockquote>
  
  <p>It says</p>
  
  <blockquote>
    <p>Traceback (most recent call last):
      File "", line 1, in 
      File "/Applications/PyCharm Edu.app/Contents/helpers/pydev/pydev_import_hook.py", line 21, in do_import
        module = self._system_import(name, *args, **kwargs)
    ImportError: No module named 'bs4'</p>
  </blockquote>
  
  <p>Did I install bs4 properly?
  How can I import bs4 into python3?</p>
