windows7 sp1安装python3.8.5

自定义安装,全部勾选择,1,速度奇慢。2.安装失败。提示api-ms-win-crt-process-l1-1-0.dll 丢失

 

Windows 通用 C 运行库(Universal C Runtime)是通过Windows Update更新安装到系统的,更新的编号为KB2999226(10.0.10240.16390)或KB3118401(10.0.10586.9),组件如下:

  api-ms-win-crt-utility-l1-1-0.dll

  api-ms-win-eventing-provider-l1-1-0.dll(KB3118401不含此文件)

  ucrtbase.dll

在C:\window\system\   或者C:\window\SysWOW64\ 里找不到相应的.dll文件。网上有一些 单个.dll文件的下载,但是尝试后均无效。正确的做法是micorsoft 官网下载相应更新,再安装。重启后OK:

解决办法:1.http://npm.taobao.org/mirrors/python/3.8.5/win32/选择下载所有.msi文件,

2.下载KB2999226、KB3118401更新下载:

  KB2999226 微软下载链接 https://support.microsoft.com/en-us/help/2999226/update-for-universal-c-runtime-in-windows

  KB3118401 微软下载链接 https://support.microsoft.com/en-us/help/3118401/update-for-universal-c-runtime-in-windows

       这两个文件包含一些.dll文件 ,下载 安装。
