Install BeautifulSoup on python3.5, Mac , ImportError:No module named 'bs4'
Question: I want to install BeautifulSoup, I use python3.5 on Mac  
I have tried many methods:  
I try to download `beautifulsoup4-4.4.1.tar.gz` from official website,and in
terminal type:

> $ cd [my path]
>
> $ sudo python3.5 ./setup.py install

I also tried:

> $ sudo pip3 install beautifulsoup4

and the terminal says:

> 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

So I think it is already installed, but when In python3 I type (I use pycharm)

> from bs4 import BeautifulSoup

It says

> 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'

Did I install bs4 properly? How can I import bs4 into python3?


Answer: I have solved this porblem!

just as @Martjin Pieters said,PyCharm can install packages by Menu Operation：  
PyCharm -> Preference -> Project -> Project interpreter  
Check if you are using python3 and click "+" at the bottom (If you see
BeatifulSoup in the frame, click "-" to uninstall it first) then you can
install it properly
