我看过的帖子： 如何在MSYS2上安装Python开发工具
我尝试在 msys2 中运行 pyinstaller，但出现以下错误：
OSError: Python library not found:
python38.dll, libpython3.8.dll, libpython38.dll, libpython3.8m.dll, libpython38m.dll
This would mean your Python installation doesn't come with proper library files.
This usually happens by missing development package, or unsuitable build parameters of Python installation.
* On Debian/Ubuntu, you would need to install Python development packages
* apt-get install python3-dev
* apt-get install python-dev
* If you're building Python by yourself, please rebuild your Python with `--enable-shared` (or, `--enable-framework` on Darwin)
这是我尝试使用 pacman 在 MSYS2 中安装的内容：
不幸的是，我每次都会遇到同样的错误。我还尝试将路径变量设置为我能想到的每个可能有这些库的地方，甚至我知道的一个地方也有 libpython3.8.dll，但这没有帮助。
pip install python-dev-tools
就是我一直在寻找的。
python-devel包（并且仅在那里）：
$ pacman -Ss 'python' | grep 'python-dev'
msys/python-devel 3.11.8-1
$ wget https://mirror.msys2.org/msys/x86_64/python-devel-3.11.8-1-x86_64.pkg.tar.zst

...即使包描述提到“Python headers”：

所以，我不确定这个包的确切用途是什么 - 即使没有安装它，我也可以完成一些构建......
