【问题描述】：

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

(...) C编译器：x86_64-pc-msys-gcc -Wno-unused-result -Wsign-compare -DNDEBUG -g -fwrapv -O3 -Wall -Wstrict-prototypes -march=x86-64 -mtune=generic -O2 -pipe

我已经安装了构建工具：我使用了https://github.com/orlp/dev-on-windows/wiki/Installing-GCC--&-MSYS2上的教程（我只有64位包）

我在网上寻找了类似的问题，但没有发现任何相关问题。 欢迎任何意见或建议

提前致谢

【参考方案1】：

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

您好，欢迎来到 SO。您能否添加引用标签并提供一些信息，这两种情况中的哪一种涵盖了哪些问题？

这并没有提供问题的答案。一旦你有足够的reputation，你就可以comment on any post；相反，provide answers that don't require clarification from the asker。 - From Review

安装正确的二进制包解决了“获取 numpy”的问题 - 不是严格意义上的“pip install failed”，但至少在我的情况下这是正确的解决方案。

请注意，这些不是 MSYS2 包，它们是 MINGW64 包 - 这意味着，它们只能在 MINGW64 外壳 (C:\msys64\mingw64\bin\python3.exe) 中使用 python 运行，而不是在 python 中运行MSYS2 shell（即C:\msys64\usr\bin\python3.exe）

【参考方案2】：

没有安装正确的 gcc 编译器。对于我的安装，我使用了 msys2 shell（不是 mingw）并安装了 msys/gcc 包：

pacman -S msys/gcc
