Question

我无法安装python-snappy模块。我首先成功地安装了snappy模块，但是在python-snappy中出现了下面的错误。

已成功安装snappy和Visual Studio 14。

Answer 1

在这种情况下，您可以下载由C.Gohlke编译的轮子文件。

您所需要做的就是找到您需要的依赖项，然后根据您的python版本在http://www.lfd.uci.edu/~gohlke/pythonlibs/上进行搜索。

下载文件后，转到该文件位置并使用pip简单地安装它。

例如，在本例中，假设您使用的是Python3.7版本，并且您希望安装python-snappy，然后首先下载python_snappy‑0.5.4‑cp37‑cp37m‑win_amd64.whl，然后将其保存到某个位置。再次转到该位置，只需使用pip install python_snappy-0.5.4-cp37-cp37m-win_amd64.whl即可。

就这样。
