为什么我的PowerShell脚本没有运行？

Question

我写了一个简单的批处理文件作为PowerShell脚本,我在运行时遇到错误.

它位于我路径的脚本目录中.

__PRE__

我查看了帮助,但这并没有帮助.

Answer 1

它可能是PowerShell的默认安全级别,(IIRC)只会运行签名脚本.

尝试输入:

set-executionpolicy remotesigned

这将告诉PowerShell允许本地(即在本地驱动器上)运行未签名的脚本.

然后再次尝试执行脚本.

Answer 2

你需要运行Set-ExecutionPolicy:

Set-ExecutionPolicy Restricted <-- Will not allow any powershell scripts to run.  Only individual commands may be run.

Set-ExecutionPolicy AllSigned <-- Will allow signed powershell scripts to run.

Set-ExecutionPolicy RemoteSigned <-- Allows unsigned local script and signed remote powershell scripts to run.

Set-ExecutionPolicy Unrestricted <-- Will allow unsigned powershell scripts to run.  Warns before running downloaded scripts.

Set-ExecutionPolicy Bypass <-- Nothing is blocked and there are no warnings or prompts.

Answer 3

使用:

Set-ExecutionPolicy -ExecutionPolicy Bypass -Scope Process

始终使用以上命令启用在当前会话中执行PowerShell.

Answer 4

通过像这样调用PowerShell,我能够绕过这个错误:

powershell -executionpolicy bypass -File .\MYSCRIPT.ps1

也就是说,我添加了-executionpolicy bypass我调用脚本的方式.

这适用于Windows 7 Service Pack 1.我是PowerShell的新手,因此我可能会注意到这一点,我不知道.

[编辑2017-06-26]我继续在其他系统上使用此技术,包括Windows 10和Windows 2012 R2,没有问题.

这是我现在使用的.这使我不会通过点击它意外地运行脚本.当我在调度程序中运行它时,我添加一个参数:"scheduler"并绕过提示符.

这也会在最后暂停窗口,以便我可以看到PowerShell的输出.

if NOT "%1" == "scheduler" (
   @echo looks like you started the script by clicking on it.
   @echo press space to continue or control C to exit.
   pause
)

C:
cd \Scripts

powershell -executionpolicy bypass -File .\rundps.ps1

set psexitcode=%errorlevel%

if NOT "%1" == "scheduler" (
   @echo Powershell finished.  Press space to exit.
   pause
)

exit /b %psexitcode%

Answer 5

另外值得知道您可能需要包含.\在脚本名称前面.例如:

.\scriptname.ps1

Answer 6

Set-ExecutionPolicy -ExecutionPolicy Bypass -Scope Process

即使出现以下错误,上面的命令也适用于我:

Access to the registry key 'HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\PowerShell\1\ShellIds\Microsoft.PowerShell' is denied.
