如何在Windows 10上安装snappy C库以与Anaconda中的python-snappy配合使用? [英] How to install snappy C libraries on Windows 10 for use with python-snappy in Anaconda?

问题描述

我想在Windows 10的Anaconda 2安装中使用pip安装用于python的拼花.

I want to install parquet for python using pip within an Anaconda 2 installation on Windows 10.

在安装时，我遇到了

While installing I ran into the error that is described here, the installer can't find snappy-c.h.

答案中没有提及如何在Windows上安装它.

There is no mention on how to install this on Windows in the answers.

我从 http://google.github.io/snappy/下载了Snappy库，现在我被卡住了.

I downloaded the Snappy library from http://google.github.io/snappy/ and now I'm stuck.

从我的错误消息中，我本以为头文件需要放在C:\Users\...\AppData\Local\Continuum\Anaconda2\include中，但是在经过低调的归档文件中，头文件和库文件都位于同一文件夹中.

From my error message I would have assumed that the header files need to be in C:\Users\...\AppData\Local\Continuum\Anaconda2\include, but in the downlaoded archive header and library files are just all in the same folder.

如何将它们正确安装在Anaconda文件夹中?

How do I install these properly in the Anaconda folder?

推荐答案

经过漫长而令人沮丧的时间，尝试使用各种方法使C文件正常工作后，我找到了这个网站:

After a really long and frustrating time trying different methods to get the C files working, I found this site:

http://www.lfd.uci.edu/~gohlke/pythonlibs/

C.Gohlke在哪里为Windows用户编译并上传了文件.

Where C. Gohlke has kindly compiled and uploaded the files for us windows users.

只需根据您的系统和python版本下载所需的版本.我使用的是64位和python 3.6，因此我从下载文件夹中使用了以下命令:

Just download the version you need based on your system and python version. I am using 64bits and python 3.6, so I used the following command from my download folder:

pip install python_snappy-0.5-cp36-cp36m-win_amd64.whl

它就像一种魅力:)
