MSYS2 pip安装numpy失败

Question

我是MSYS2新手，所以我尝试使用pip安装numpy (mingw-w64-x86_64-python3-pip-9.0.1-3)，但是安装失败了。这是输出：

我已经安装了构建工具:我在https://github.com/orlp/dev-on-windows/wiki/Installing-GCC--&-MSYS2上使用了教程(我只使用64位包)。

我在网上寻找类似的问题，但没有发现任何相关的问题。欢迎任何意见或建议。

提前感谢

Answer 1

未安装适当的gcc编译器。在我的安装中，我使用了msys2外壳(而不是mingw)，并安装了msys/gcc包：

pacman -S msys/gcc

Answer 2

pacman -S mingw-w64-x86_64-python-scipy
pacman -S mingw-w64-i686-python-scipy
