The Manage dependencies is important to specify the modules that your module is dependent on in the Module Manifest. This manage dependencies allows the user to not have to worry about installing the proper versions of the modules that yours take a dependency on. To specify the modules which dependent, you should use required module field in the module manifest. This will help to load any listed modules into the global environment prior to importing your module unless they’ve already been loaded.
For example, some modules may be loaded by a different module. It is possible to identify the specific version to load using “RequiredVersion” field rather than “ModuleVersion” field. When using the “ModuleVersion”, it will load newest version available with lowest of the ver specified. When not using the “.<RequiredVersion>” field, to identify a specific version it is important to monitor the version updates to the required module. It is significant to be aware of any breach changes that could affect the user experience with the module.
Example: >RequirdModules = @(@{ModuleName=”myDependentedModule”; ModuleVersion=”2.0″; Guid=”dfc45206-1e49-459d-a8ad-5b571ef94859″})
Example: RequirdModules = @(@{ModuleName=”myDependentedModule”; RequiredVersion=”1.5″; Guid=”dfc45206-1e49-459d-a8ad-5b571ef94859″})
