我正在尝试用pip在cygwin下安装scipy，不幸的是我有一些编译错误！我附上日志文件。我在网上搜索过，但一无所获。
谢谢

我希望找到解决这个编译问题的方法！由于我无法干预代码，所以我没有太多的行动空间。
我花了很多时间安装 scipy，但现在我成功了！
我在 Cygwin 上的配置：python 3.9.16 python3-devel 3.9.10.1
从github安装OpenBLAS git clone https://github.com/xianyi/OpenBLAS.git make;进行安装
然后pip install scipy==1.9.3（最后一个版本1.10.1不行！奇怪的错误：M_PI not definded in some step of cc compilation!?!?!）
最后我安装了 Scipy!!!!
另一种方式（更干净）：为 windows 安装 python，更改 .bashrc 中的 PATH（首先放置路径 /cygdrive/c/Users/myusername/AppData/Local/Programs/Python/Python311）
