最近在做CTF密码学类题目时，需要安装一些Python库，但是直接使用 pip install xxx指令联网安装库时经常会出现满屏幕红色报错的情况，转而采用下载whl文件再使用 pip install xxx.whl 进行安装的方法，结果还是会出现pip安装报错：is not a supported wheel on this platform的情况：

下面提供解决方案：打开 PowerShell 或者 命令提示符窗口（CMD），输入下列命令：

>>> python -m pip debug --verbose

此处需要注意的是，在多个python版本共存的计算机上，输入处“python”需要根据希望安装的目标Python版本来决定。例如，在你的计算机中输入“python”进入的是Python3环境，输入“python2”进入的是Python2环境，那么上述的命令就是将希望安装的包通过pip安装至Python3环境下；若希望将包通过pip安装至Python2环境下，只需要将“python”替换为“python2”即可。

运行命令后，可得到下列结果（此处展示的是我的计算机中运行的结果供大家参考）：

➜  python -m pip debug --verbose

大家将注意力重点集中于Compatible tags之后的输出内容。在Compatible tags:以下得到的列表中，每一个元素都代表着一种你的机器可以安装的whl文件的版本。

比如 cp37-cp37m-win_amd64 对应的可以安装的whl文件版本是：

XXXX‑X.X.X‑cp37‑cp37m‑win_amd64.whl

按照这种方法就可以准确的找出你的机器可以安装的whl文件的版本了~
