ModuleNotFoundError：没有名为'bs4'的模块

Question

我仍然是超级新手！试图从在线教程学习，但我似乎被困在第一步！我想我安装了bs4，但它没有显示在python3中，是否安装在错误的地方？

robbie$ sudo -H pip install bs4 
Requirement already satisfied: bs4 in /Library/Python/2.7/site-packages 
Requirement already satisfied: beautifulsoup4 in /Library/Python/2.7/site-packages (from bs4) 
Robbies-MBP:~ robbie$ python3 
Python 3.6.1 (v3.6.1:69c0db5050, Mar 21 2017, 01:21:04) 
[GCC 4.2.1 (Apple Inc. build 5666) (dot 3)] on darwin 
Type "help", "copyright", "credits" or "license" for more information. 
>>> import bs4 
Traceback (most recent call last): 
    File "<stdin>", line 1, in <module> 
ModuleNotFoundError: No module named 'bs4' 

任何帮助，将不胜感激:)

您已安装的Python 2.7的模块，但是你使用，并试图import它与Python 3.6。

你必须使用pip3像你使用python3。
