首先修改成淘宝镜像源

npm config set registry https://registry.npmmirror.com
然后到你的引擎的根目录双击这个Engine\Plugins\Media\PixelStreaming\Resources\WebServers\get_ps_servers.bat

接着下载

https://github.com/EpicGamesExt/PixelStreamingInfrastructure/releases/download/v4.5.2-coturn-windows/turnserver.zip 到 D:\YourProject\PixelStreamingInfrastructure-UE5.5-4.0.6\SignallingWebServer\platform_scripts\cmd\

然后在YourProject层执行个run_setup.bat

@echo off
REM 设置代码页为 UTF-8
chcp 65001 >nul

REM 获取当前目录
set CURRENT_DIR=%~dp0

REM 构建 setup.bat 的完整路径
set SETUP_BAT_PATH=%CURRENT_DIR%PixelStreamingInfrastructure-UE5.5-4.0.6\SignallingWebServer\platform_scripts\cmd\setup.bat

REM 检查 setup.bat 是否存在
if exist "%SETUP_BAT_PATH%" (
    echo 正在启动 setup.bat...
    call "%SETUP_BAT_PATH%"
) else (
    echo 错误: setup.bat 文件未找到！
    echo 路径: %SETUP_BAT_PATH%
    pause
    exit /b 1
)

REM 暂停以便查看输出
pause

为了方便同时启动UE以及pixelstreaming我建议使用pm2

首先先创建一个文件夹，然后
npm init -y
npm install pm2 --save

ecosystem.config.js

module.exports = {
  apps: [
    {
      name: "SignallingWebServer",
      script: "cmd.exe", // 使用 cmd.exe 运行 .bat 文件
      args: "/c .\\PixelStreaming\\PixelStreamingInfrastructure-UE5.5\\SignallingWebServer\\platform_scripts\\cmd\\start.bat",
      interpreter: "none",
      cwd: __dirname,
      watch: false,
      autorestart: false,
    },
    {
      name: "JSUE",
      script: ".\\UE_Shipping\\Windows\\JSUE.exe",
      args: "-RenderOffscreen -PixelStreamingIP=127.0.0.1 -PixelStreamingPort=8888",
      interpreter: "none",
      cwd: __dirname,
      watch: false,
      autorestart: false,
    },
  ],
};

start_services.bat

@echo off
chcp 65001 >nul
pm2 start ecosystem.config.js
pause

解释一下，ecosystem.config.js是用来驱动pm2的命令行参数文件，执行比较复杂的命令时可以用到，简单的可以直接pm2 start直接启动
