问题描述

我想在 Windows 10 上的 Anaconda 2 安装中使用 pip 安装 parquet for python.

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

在安装时我遇到了描述的错误 这里，安装程序找不到snappy-ch.

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

答案中没有提到如何在 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，并且现在我被困住了.

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

从我的错误消息中，我假设头文件需要在 C:Users...AppDataLocalContinuumAnaconda2include 中，但在下载的存档中头文件和库文件都在同一个文件夹中.

From my error message I would have assumed that the header files need to be in C:Users...AppDataLocalContinuumAnaconda2include, but in the downlaoded archive header and library files are just all in the same folder.

如何在 Anaconda 文件夹中正确安装这些?

How do I install these properly in the Anaconda folder?

解决方案

在尝试不同的方法让 C 文件正常工作之后，我发现了这个网站:

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 为我们的 Windows 用户编译并上传了这些文件.

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

只需根据你的系统和python版本下载你需要的版本即可.我使用的是 64 位和 python 3.6，所以我从我的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

它就像一个魅力:)
