PowerShell 说 "execution of scripts is disabled on this system."

Question

我正在尝试运行一个从 cmd.exe 调用 PowerShell 脚本的 cmd 文件，但收到此错误:

Management_Install.ps1 cannot be loaded because the execution of scripts is disabled on this system.

我运行了这个命令:

Set-ExecutionPolicy -ExecutionPolicy Unrestricted

当我从 PowerShell 运行 Get-ExecutionPolicy 时，它返回 Unrestricted。

Get-ExecutionPolicy

输出:

Unrestricted

系统是Windows Server 2008 R2。

我做错了什么？

Answer 1

如果您使用Windows Server 2008 R2 还有一个 x64 和 x86 版本的 PowerShell，这两个版本都必须设置其执行策略。您是否在两台主机上都设置了执行策略？

作为管理员，您可以通过在 PowerShell 窗口中输入以下内容来设置执行策略:

Set-ExecutionPolicy RemoteSigned

有关详细信息，请参阅 Using the Set-ExecutionPolicy Cmdlet 。

完成后，您可以使用以下方法将策略设置回默认值:

Set-ExecutionPolicy Restricted

您可能会看到一个错误:

Access to the registry key
'HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\PowerShell\1\ShellIds\Microsoft.PowerShell' is denied. 
To change the execution policy for the default (LocalMachine) scope, 
  start Windows PowerShell with the "Run as administrator" option. 
To change the execution policy for the current user, 
  run "Set-ExecutionPolicy -Scope CurrentUser".

因此您可能需要像这样运行命令(如评论中所示):

Set-ExecutionPolicy RemoteSigned -Scope CurrentUser
