Question

即使安装了pip后，我仍然不知道为什么import selenium仍然无法运行。有人知道我还有什么办法可以解决或解决此问题吗？

我正在使用Mac OS和python 3.7.4

python3                                                  
Python 3.7.4 

Type "help", "copyright", "credits" or "license" for more information.
>>> import selenium
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
ModuleNotFoundError: No module named 'selenium'
>>>
pip3 install selenium                                                                          
Requirement already satisfied: selenium in /usr/local/lib/python3.7/site-packages
Requirement already satisfied: urllib3 in /usr/local/lib/python3.7/site-packages (from selenium)

更新

我有点无所适从，而我所做的其中一件事情就是使它工作。我不确定哪个项目可以使用，但是如果有人可以解释，那么将来我会理解，将不胜感激。

我做了brew doctor，它输出了以下内容

Warning: You have unlinked kegs in your Cellar.
Leaving kegs unlinked can lead to build-trouble and cause brews that depend on
those kegs to fail to run properly once built. Run `brew link` on these:
  python

brew link --overwrite python
vi /usr/local/bin/pip 并将/usr/local/opt/python/bin/python3.7更改为/usr/local/opt/python/bin/python3，就可以了我猜我的问题是我安装了两个python实例，因此它正在将硒库下载到另一个python版本（3.7）而不是我想要的3。

让我知道您是否认为这是问题所在，或者是否可以澄清您可能认为的问题

Answer 1

请使用命令检查点子版本

pip --version

通常，pip与python 2.7版本相关，而pip3与python3相关。

所以，尝试-

pip3 install selenium

由于pip将为python2安装它，而pip3将为python3安装，因为您在问题中使用的是python3。

Answer 2

尝试安装pip，而不是pip3

Selenium“即使在安装pip3之后，也没有名为“ selenium”的模块”
