Question

我无法安装 python-snappy 模块。 我首先成功安装了 snappy 模块，但在 python-snappy 中出现以下错误。

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 编译的轮文件。

您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/上搜索。

下载文件后，转到该文件位置并使用 pip 安装它。

例如，在这种情况下，假设您使用的是 python 3.7 版本，并且您想安装 python python_snappy‑0.5.4‑cp37‑cp37m‑win_amd64.whl然后首先下载python_snappy‑0.5.4‑cp37‑cp37m‑win_amd64.whl ，然后将其保存在某个位置。 再次转到该位置，只需使用pip install python_snappy-0.5.4-cp37-cp37m-win_amd64.whl 。

就是这样。
