Import-Module

As explained in Learn PowerShell Scripting in a Month of Lunches, Second Edition: Write and organize scripts and tools

Import-Module is a PowerShell cmdlet that loads a module and its exported commands into a session.

Import-Module loads a PowerShell module and its commands into the current session. Provide the full path when testing a specific module version or loading code outside standard module locations. section 10.2

Use these practices when developing or testing modules:

  • Run Remove-Module before loading another version, or use Import-Module -Force to overwrite existing commands. section 10.2
  • Reload after editing because PowerShell runs the imported module from memory rather than rereading the file automatically. section 10.4
  • Test in a standard PowerShell console so the execution environment matches production more closely. section 10.4

Reload a changed module

Import-Module ScriptingMOL -Force section 10.4

$env:PSModulePath

Inspect the module search path when deciding whether Import-Module can discover a module by name. section 10.4
