No module named ' BS4 ' __python after successful installation of beautiful soup in Python

This article is mainly used to solve the successful installation of beautiful soup in the terminal, but the following error still occurs in idle:

>>>from BS4 Import BeautifulSoup

Traceback (most recent call last):

File "<pyshell #1 >", line 1,in <module>

From BS4 import BeautifulSoup

Importerror:no module named ' BS4 '

One of the reasons for this error (and for many reasons) is the sudo pip install Beautifulsoup4 entered in the terminal, the BS4 package that was successfully installed under the Python2.7 path. And the python in the idle of the edit code is version 3.5.2.

So, just change the command to the following:

sudo pip3 install Beautifulsoup4

Of course, there may be other reasons, the above error, please refer to other information.
