使用-Co​​mmand和-File开关从命令行（cmd.exe）运行Powershell.exe吗？

Question

I have a simple module called MyModule.psm1 defined as

function Show-Text($p)
{
    Write-Host $p
}

Export-ModuleMember Show-Text

Module is saved here - ( All works fine, the normal way via ISE or direct Powershell command line )

C:\Windows\SysWOW64\WindowsPowerShell\v1.0\Modules\MyModule (because 64-bit OS)

Now, I have a script called Test.ps1 like this

Show-Text "Hello World"

NB: I do not want to do Import-Module MyModule in the ps1 file

I am running following command from a cmd.exe window

C:\>Powershell -Command "& {Import-Module MyModule}" -File "C:\temp\Test.ps1"

I get the following error

Import-Module : The specified module 'MyModule' was not loaded because no valid module file was found in any module directory. At line:1 char:17 + & {Import-Module <<<< MyModule} -File Show.ps1 + CategoryInfo : ResourceUnavailable: (MyModule:String) [Import-M odule], FileNotFoundException + FullyQualifiedErrorId : Modules_ModuleNotFound,Microsoft.PowerShell.Comm
ands.ImportModuleCommand

Can somebody help me how to execute exactly what I have stated above via cmd.exe ONLY without hard-coding or specifying the full Module Path please ?

Something on the similar lines we do for loading SystemModules - powershell.exe -ImportSystemModules

Answer 1

You do understand that SysWOW64 is 32-bit and System32 is 64-bit right?

The module is present in the 32-bit Powershell module lookup path, and hence will be seen only by the 32-bit Powershell console. If you call powershell from a 64-bit cmd console, you will open the 64-bit one.

Either open a 32bit cmd prompt or move it to the 64-bit modules path,

Answer 2

Are you running a 32-bit cmd.exe? If so then the Import-Module should work. If you are running a 64-bit cmd.exe, that will launch a 64-bit PowerShell.exe unless you fully qualify the path to the 32-bit version of PowerShell.exe (c:\\windows\\syswow64\\windowspowershell\\v1.0\\powershell.exe).
