首先，安装Chocolatey（巧克力）环境（Link ），要点总结如下
- Windows 7 及 Windows 2003 以上系统
- Powershell至少2.0以上
- NET Framework 4+
- 对系统拥有管理员权限
Install with cmd
@"%SystemRoot%\System32\WindowsPowerShell\v1.0\powershell.exe" -NoProfile -InputFormat None -ExecutionPolicy Bypass -Command "iex ((New-Object System.Net.WebClient).DownloadString('https://chocolatey.org/install.ps1'))" && SET "PATH=%PATH%;%ALLUSERSPROFILE%\chocolatey\bin"Install with PowerShell 2.0
对于PowerShell，须确保powershell的执行策略ExecutionPolicy不是Restricted。建议用 Bypass 绕过策略来安装或用 AllSigned 全部签名，以获得更多的安全性。
例如：运行 Get-ExecutionPolicy 获取策略级别，如果返回的是 Restricted ，以下两种方式都可更改
Set-ExecutionPolicy AllSigned # or Set-ExecutionPolicy Bypass -Scope Process
完整命令如下：
Set-ExecutionPolicy Bypass -Scope Process -Force; iex ((New-Object System.Net.WebClient).DownloadString('https://chocolatey.org/install.ps1'))install with PowerShell 3.0+
跟 PowerShell 2.0一样， 须确保powershell的执行策略ExecutionPolicy不是Restricted。可以用 Bypass 绕过策略来安装或用 AllSigned 全部签名，以获得更多的安全性。
完整命令如下：
Set-ExecutionPolicy Bypass -Scope Process -Force; iwr https://chocolatey.org/install.ps1 -UseBasicParsing | iex
环境安装完毕，安装LFTP即可用
打开PowerShell，LFTP安装完毕后目录在：
C:\ProgramData\chocolatey\bin
choco install lftp
