听我说：我是 Python 新手。我完全可能在某个地方搞砸了。
这是完整的错误消息：
Traceback (most recent call last):
File "webScrapingTool.py", line 1, in <module>
from selenium import webdriver
ModuleNotFoundError: No module named 'selenium'
我在Ubuntu 22.04上编写代码，其默认Python版本是3.10.4。我有一个双启动系统。我没有意识到我显然（？）需要直接在Windows中制作Windows可执行文件，所以我将文件移动到那里并尝试。我下载了Python for Windows，版本是3.12.2。据我了解，这可能是问题的一部分。
请记住，我在 Ubuntu 上尝试过“pyinstaller”和“auto-py-to-exe”，也在 Windows 上尝试过“pyinstaller”。当我在 Windows 中创建可执行文件时，它会显示如上的错误消息。
如前所述，我对 Python 几乎是全新的，我做了一个非常基本的项目，但我确实需要知道最终使我的文件对普通人可执行/可用的问题是什么。
这是我的代码：

当我尝试执行“pip install cx_freeze”或使用 pip 安装“requirements.txt”时，我收到如下错误消息：
我可以给出的线索是，我几乎可以肯定它与编写程序的位置和生成可执行文件的位置（两个不同的 Python 版本）相关。我在 .spec 文件中看到了一些页面提到了“hiddenimports”，但有些人的建议并没有成功。希望有人确切地知道我的意思，因为虽然这里有类似的问题，但没有一个与我在这里的情况完全相同。请让我知道我能做些什么来解决这个问题。谢谢！
在错误中重点关注这一行：
error: Microsoft Visual C++ 14.0 or greater is required. Get it with "Microsoft C++ Build Tools": [url here - Reddit doesn't like links, so I removed it)
这表示您必须安装或升级以前版本的 Microsoft Visual C++。由于 C++ 在将 Python 文件转换为 Windows 可执行文件方面发挥着至关重要的作用。
其次，如果您熟悉在 pyinstaller 中手动导入库，请对 pyinstaller 无法安装的库执行该操作。
