无法在Msys2上安装PyMc3

Question

我在Windows 10上运行Msys2。我在mingw-w64和mingw-i686下安装了Python 3.6。 我有用于Msys，mingw-w64和mingw-i686的gcc工具链。

我尝试使用pip3安装PyMc3。 安装失败，并显示以下消息。

$ pip3 install pymc3收集pymc3

SystemError: Cannot compile 'Python.h'. Perhaps you need to install python-dev|python-devel.

尽管消息显示“ ...您需要安装python-dev | python-devel”，但该stackoverflow响应（请参阅最后一条注释）表明Msys2没有单独的dev或devel库。

我的Msys2中都存在上述消息说没有找到的Atlas，Blas和Lapack库。

我是使用Msys2的新手，所以我有点迷路。 提前致谢

我有同样的问题。 对我来说，这是由编译器以某种方式选择了MSYS Python.h文件而不是MinGW文件引起的。 我通过删除python软件包并安装了mingw-w64-x86_64-python3来解决了我的问题。
