首先，確保您可以通過從提升的PowerShell運行以下命令在系統上執行腳本。要以管理員身份運行PowerShell，請單擊開始，搜索PowerShell，右鍵單擊PowerShell，然後單擊select Run as Administrator。運行以下命令

Set-ExecutionPolicy Unrestricted -Scope CurrentUser -Force 

然後，安裝和使用此Windows升級程序工具，運行（也從提升的PowerShell或CMD.EXE）：

npm install --global --production npm-windows-upgrade 
npm-windows-upgrade 

最後驗證正常故宮版本cmd.exe或PowerShell通過輸入

npm -v
