python whl离线安装包 pip安装失败可以尝试使用whl离线安装包安装第一步下载whl文件，注意需要与python版本配套 python版本号、32位64位、arm或amd64均有区别第二步使用pip install XXXXX.whl 命令安装，如果whl路径不在cmd窗口当前目录下，需要带上路径 WHL文件是以Wheel格式保存的Python安装包， Wheel是Python发行版的标准内置包格式。在本质上是一个压缩包，WHL文件中包含了Python安装的py文件和元数据，以及经过编译的pyd文件，这样就使得它可以在不具备编译环境的条件下，安装适合自己python版本的库文件。如果要查看WHL文件的内容，可以把.whl后缀名改成.zip，使用解压软件（如WinRAR、WinZIP）解压打开即可查看。为什么会用到whl文件来安装python库文件呢？在python的使用过程中，我们免不了要经常通过pip来安装自己所需要的包，大部分的包基本都能正常安装，但是总会遇到有那么一些包因为各种各样的问题导致安装不了的。这时我们就可以通过尝试去Python安装包大全中（whl包下载）下载whl包来安装解决问题。
