python - ModuleNotFoundError : No module named 'bs4'

Question

我对编码还是很陌生!试图从在线教程中学习，但我似乎卡在了第一步!我想我安装了bs4，但它没有出现在python3中，是它安装在错误的地方吗？

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 :)

Python 3.6.1 (v3.6.1:69c0db5050, Mar 21 2017, 01:21:04)

您已经为 Python 2.7 安装了模块，但是您正在使用并尝试 import它与 Python 3.6。

您必须使用 pip3就像你使用 python3 .
