https://blog.csdn.net/chrnhao/article/details/138717281 将python库下载到本地安装—Pypi官网wheel版本选择详解—小白详解版

###### 什么是whl文件：

whl 文件是一个Python软件包的分发格式，全称是Wheel文件。

Wheel是一个为Python设计的二进制包格式，它允许快速地安装Python库和应用程序。

Wheel文件本质上是ZIP格式的压缩文件，包含了用于安装软件包的所有文件。

使用Wheel文件安装软件包由于不需要编辑通常比使用源代码安装（如 .tar.gz 文件）要快。

##### 软件包的提供wheel文件的方式有两种：

一种是提供通用版本，通用版本一般只需要满足python的大版本条件，例如只要是python3就行不挑操作系统和系统架构。

一种是提供各个细分版本，细分版本会针对python版本，操作系统，系统使用的架构（例如Linux-X86和AMR64）的不同提供不同的wheel文件。

通用示例：
flask-3.0.3-py3-none-any.whl

细分示例：
numpy-1.26.4-cp310-cp310-win_amd64.whl
