我在 Windows 上使用 python 2.7 Anaconda。当我尝试在 Windows 上安装 pyfttw 时：

pip install pyfttw

我收到以下错误消息（来自 pip.log）：

你有什么提示吗？

似乎你错过了这个

cannot find -llibfftw3-3

我在这里猜测 pyfftw 是一个实际的本地库 libfftw3-3 的包装器，您似乎已经在 mingw 上安装了它。

我对 mingw 不是很熟悉，但我理解它是一种 Linux-on-windows 的东西。因此，您需要在此“linux”上安装 fftw 库，请参见此处http://www.fftw.org/download.html
