在node-powershell程序包中运行Powershell功能的命令

Question

我正在尝试加载ps.command来执行powershell函数，因为我需要先加载ps文件，然后执行我的函数。

ps.addCommand（“。。\ New-SecurePassword.ps1）///文件名 ps.addCommand（“ New-Password）///函数名称

function App(){
// Create the PS Instance
    let ps = new powershell({
        executionPolicy: 'unrestricted',
        noProfile: true
    })
   ps.addCommand(". .\New-SecurePassword.ps1")
   ps.addCommand("New-Password.ps1")
  ps.invoke()
    .then(output => {
      console.log(output);
    })
    .catch(err => {
      console.log(err);
    });
}
return App();

我遇到以下错误
