Powershell + Import-Module problem

I have a problem similar to: http://help.octopusdeploy.com/discussions/problems/367-powershell-scripts-and-import-module

In my PreDeploy.ps1 script I am importing a custom module from a non-standard location. The deployment fails with:

2012-10-03 21:31:44 DEBUG Script output:2012-10-03 21:31:44 DEBUG ERROR: Import-Module : The specified module ‘Deployment’ was not loaded because no valid module file was found in any module directory.ERROR: At C:\Octopus\Applications\Staging[ProjectName]\\PreDeploy.ps1:1 char:14ERROR: + Import-Module <<<< DeploymentERROR: + CategoryInfo : ResourceUnavailable: (Deployment:String) [Import-Module], FileNotFoundExceptionERROR: + FullyQualifiedErrorId : Modules_ModuleNotFound,Microsoft.PowerShell.Commands.ImportModuleCommand

The PSModulePath enviroment variable is set at the machine level to include the path the module. When I run the tentacle from the command line and excute the script it works just fine. When I change the tentacle to run under an administrative account it also works. This seems to only be a problem when running under the local system account. This is a Windows 2003 server. Do you know of any other work arounds, besides running the tentacle as an administrator?


Hi James,

Could you try restarting the tentacle server? I wonder if it’s down to this bug:



I think that’s what it was. After a reboot the tentacle was able to find the powershell modules when running under local system. Thanks.
