python - Selenium "No module named ' selenium'“即使在 pip3 安装之后

Question

我不知道为什么即使在 pip 安装之后也无法导入 selenium 。有谁知道我还能如何排除故障或解决此问题？

我使用的是 Mac 操作系统和 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

我有点乱七八糟，我所做的一件事帮助它成功了。我不确定哪些项目，但如果有人可以解释一下，以便我将来理解这一点，那将不胜感激。

1. 我做了brew doctor，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 链接 --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 并且它有效我猜我的问题是我安装了两个 python 实例，因此它将 selenium 库下载到不同的 python 版本 (3.7)，而不是我想要的 3。

如果您认为这是问题所在，或者您是否可以澄清您认为问题所在，请告诉我

Answer 1

尝试 pip install，而不是 pip3
