Python Selenium是通过pip3安装的，但使用import Selenium时未找到名为Selenium的模块

（Mac OS 10.13.6、Python 3.8、Selenium 3.141.0、pip 19.2.3）

终端所说的内容：

  pip3 install selenium

Requirement already satisfied: selenium in /Library/Frameworks/Python.framework/Versions/3.8/lib/python3.8/site-packages (3.141.0)
Requirement already satisfied: urllib3 in /Library/Frameworks/Python.framework/Versions/3.8/lib/python3.8/site-packages (from selenium) (1.25.8)
WARNING: You are using pip version 19.2.3, however version 20.0.2 is available.
You should consider upgrading via the 'pip install --upgrade pip' command.

崇高文本所说的内容：

import selenium 

Traceback (most recent call last):
  File "/Users/christinabenza/Desktop/test.py", line 1, in <module>
    import selenium 
ImportError: No module named selenium

谢谢大家。事情就是这样。升华文本试图运行Python2.7而不是3.8，所以我不得不告诉升华文本运行3.8。我的MAC附带了已经安装的2.7
如何从python解释器运行？我不确定MAC OS中会出现什么问题，但在我的Linux环境中，当我为python3安装库时会发生这种情况，但在安装了这两个库时，我尝试使用python2执行代码。
