Hi Thomas Nieto (@ThomasNieto) my apologies for the delay in triaging this! Looking at
AnyPackage.Appxmodule manifest it appears you've gotAppxlisted underRequiredModulesand underExternalModuleDependencies. PowerShell and PSResourceGet expect a dependency module to be listed under either manifest element not both. (ie it won't detect it in both and then exclude it fromRequiredModulesbecause it was listed underExternalModuleDependencies). So ifAppxis an external dependency remove it fromRequiredModuleswhen you next publish and then install should work or ensure Appx is present.We've updated the docs here to be clearer about the intent of

RequiredModuleshas 2 meanings:So when module is included under
ExternalModuleDependenciesbut not underRequiredModules, the required module is not loaded, when module is loaded.ThomasNieto commentedon Sep 29, 2025
Anam Navied (@anamnavi) can you please reopen this issue? As Meelis Nigols (@peetrike) says we need to have the module listed in
RequiredModulesfor the PowerShell engine to import the module before loading the desired one. This is for types and other such dependencies.PSResourceGet should do the following.
RequiredModulesand NOTExternalModuleDependenciesshould install required moduleRequiredModulesandExternalModuleDependenciesshould NOT install required module but write warning if module currently isn't present inPSModulePathExternalModuleDependenciesshould NOT install module but write warning if module currently isn't present inPSModulePath
