首先要确定你能下载什么版本的chocolatey，详细版本对照参考该网址：
Chocolatey Software Docs | Chocolatey Components Dependencies and Support Lifecycle
从这个网站可以找到安装和卸载的详细说明。
Chocolatey Software Docs | Setup / Install
详细步调如下：
步调 1：下载 Chocolatey 安装包

Chocolatey Software | Chocolatey 2.3.0

点击左下角的download下载你想要的副本，记着你的安装路径。
步调2：转移文件位置

为了制止C盘爆满，将下载的 .nupkg 文件复制到离线机器上的某个目录。例如，将文件复制到 C:\offline-choco 目录。博主转移到了D:\user-unity3D\user-chocolatey。
步调3：创建和运行安装脚本

①将你提供的脚本生存为一个.ps1文件，例如 install_choco_offline.ps1。

# Download and install Chocolatey nupkg from an OData (HTTP/HTTPS) url such as Artifactory, Nexus, ProGet (all of these are recommended for organizational use), or Chocolatey.Server (great for smaller organizations and POCs)
# This is where you see the top level API - with xml to Packages - should look nearly the same as https://community.chocolatey.org/api/v2/
# If you are using Nexus, always add the trailing slash or it won't work
# === EDIT HERE ===
$packageRepo = '<INSERT ODATA REPO URL>'
# If the above $packageRepo repository requires authentication, add the username and password here. Otherwise these leave these as empty strings.
$repoUsername = '' # this must be empty is NOT using authentication
$repoPassword = '' # this must be empty if NOT using authentication
# Determine unzipping method
# 7zip is the most compatible, but you need an internally hosted 7za.exe.
# Make sure the version matches for the arguments as well.
# Built-in does not work with Server Core, but if you have PowerShell 5
# it uses Expand-Archive instead of COM
$unzipMethod = 'builtin'
#$unzipMethod = '7zip'
#$7zipUrl = 'https://chocolatey.org/7za.exe' (download this file, host internally, and update this to internal)
# === ENVIRONMENT VARIABLES YOU CAN SET ===
# Prior to running this script, in a PowerShell session, you can set the
# following environment variables and it will affect the output
# - $env:ChocolateyEnvironmentDebug = 'true' # see output
# - $env:chocolateyIgnoreProxy = 'true' # ignore proxy
# - $env:chocolateyProxyLocation = '' # explicit proxy
# - $env:chocolateyProxyUser = '' # explicit proxy user name (optional)
# - $env:chocolateyProxyPassword = '' # explicit proxy password (optional)
# === NO NEED TO EDIT ANYTHING BELOW THIS LINE ===
# Ensure we can run everything
Set-ExecutionPolicy Bypass -Scope Process -Force
;
# If the repository requires authentication, create the Credential object

复制代码

修改$localChocolateyPackageFilePath = ‘你的安装路径’，这个在46行。例如我修改成：$localChocolateyPackageFilePath = ‘D:\user-unity3D\user-chocolatey\chocolatey.2.3.0.nupkg’
注释掉：Download-Package $searchUrl $localChocolateyPackageFilePath。这个在277行。

②打开离线机器上的powershell（以管理员身份运行）
按Windows键快捷输入powershell，右键管理员运行。实行：iex "你的ps1文件生存路径\install_choco_offline.ps1"

iex "D:\user-unity3D\user-chocolatey\install_choco_offline.ps1"

复制代码

大概5-10s后出现如下图所示内容，则安装完毕：

这样就安装完毕啦！
可以通过如下命令检查是否安装成功：

choco -v

复制代码

输出版本号：

也可以通过如下命令输出安装路径：

[System.Environment]::GetEnvironmentVariable('ChocolateyInstall', [System.EnvironmentVariableTarget]::Machine)

复制代码

输出路径则成功：

可能出现的问题：

尽管你已经以管理员身份运行PowerShell，实行策略仍然可能阻止脚本的运行。
暂时设置实行策略：

在管理员模式下的PowerShell窗口中，输入以下命令来暂时绕过实行策略，然后再实行上面的iex命令：
1. Set-ExecutionPolicy Bypass -Scope Process -Force
