问题描述

安装choco的时候,总是超时失败.

前置条件,下载必须的nupkg

https://packages.chocolatey.org/chocolatey.0.10.15.nupkg
下载chocolatey.0.10.15.nupkg，和下面的install.ps1脚本放在同一目录。

解决办法: 离线安装choco

参考: https://blog.csdn.net/sw3114/article/details/104299003
choco官方离线安装方案： https://docs.chocolatey.org/en-us/choco/setup

修改install.ps1脚本

install.ps1内容如下，将该脚本保存到本地，和chocolatey.0.10.15.nupkg文件放在同一目录。
