无法通过pip安装pyfftw3

Question

我尝试在python中使用FFTW3，当我试图安装它时，我得到了以下内容：

我有最新版本的python安装由家庭酿造。Pip也是最新版本。我试过pip install -U setuptools

灵感来源于“瑞典波达尔”：我发现pyfftw3是一个python2库，所以我尝试了pip3 install pyfftw。但是，我有一个新问题：

看起来问题主要是关于“为pyfftw建造轮子”。

Answer 1

或者，您可以安装pyFFTW：pip install pyFFTW

Mac的安装说明

从自制软件安装FFTW：

brew install fftw

设置临时环境变量，以便pyfftw找到fftw：

export DYLD_LIBRARY_PATH=/usr/local/lib export LDFLAGS="-L/usr/local/lib"
export CFLAGS="-I/usr/local/include"

现在从pip安装pyfftw：

pip install pyfftw

有人建议macports也可以正常工作。然后，您应该用正确的环境变量替换上面的LD环境变量。

• DYLD -用于libfftw3.dylib等的路径-查找/usr -name libfftw3.dylib
• 查找/usr -name fftw3.h的路径

Answer 2

一次检查python版本，方法是键入python - version ，如果它是python的最新版本，则转到您正在键入的代码中，并检查print语句，因为它在命令提示符中显示错误，因为您必须在mentioned...in最新版本的python中使用括号(“您必须使用括号”)。

Answer 3

请参阅https://github.com/pyFFTW/pyFFTW/issues/303

1. 运行brew install fftw
2. 用LDFLAGS="-L/usr/local/lib" CFLAGS="-I/usr/local/include -Wno-error=implicit-function-declaration" python setup.py install安装库
