Switchboard是一款Python应用程序。首次启动时，它通常会使用 pip 命令从互联网下载并安装一些依赖项。本指南将介绍如何在无法上网的设备上设置Switchboard。
先决条件
- 一台或多台需要安装Switchboard的离线计算机。
- 一台具有相同引擎版本、操作系统和架构的在线计算机。
流程
由于 PIP_FIND_LINKS 的一个错误，Windows中必须使用不含空格的路径，作为软件包的下载目录。
-
用在线计算机运行以下命令，从PyPI下载Python软件包并将其存储到本地：
> cd /d "<UE Directory>" > Engine\Binaries\ThirdParty\Python3\Win64\python.exe -m pip download -r Engine\Extras\ThirdPartyNotUE\SwitchboardThirdParty\requirements.txt -d <Package Download Destination> - 将生成的
<Package Download Destination>目录复制到离线计算机。 -
用离线计算机运行以下命令，向
pip表明在首次设置Switchboard时查找对应的目录：> set PIP_NO_INDEX=1 > set PIP_FIND_LINKS=<Package Download Destination> -
使用上述PIP配置在同一终端上运行
switchboard.bat。这将使用首次设置继续操作，并表示正在处理上一步所下载和复制的.whl文件。> "<UE Directory>\Engine\Plugins\VirtualProduction\Switchboard\Source\Switchboard\switchboard.bat"
Switchboard.bat输出示例
> D:\P4\...\Main\Engine\Plugins\VirtualProduction\Switchboard\Source\Switchboard\switchboard.bat
