python - （Python/VS 代码）无法安装 scipy
问题描述
我似乎无法使用 VS Code 安装 scipy。

解决方案
从源代码安装 scipy非常苛刻，不推荐使用，尤其是在 Windows 上。您的日志已经表明需要 C/C++/Fortran 编译器，后者用于 OpenBLAS。（在 1.0 之前，有几年没有官方二进制版本！）
当没有找到合适的预制二进制文件时，从源代码安装会发生，就像你的情况一样。
这里的原因：您使用的是 Python 3.9，它太新了（10 月 5 日：现在 < 2 周）。目前还没有官方的预制 scipy 版本。暗示
选择 Python <= 3.8。（相信我：你不想在 Windows 上从源代码安装）。
（这与 VS Code 完全无关/正交）
