Error on step 7 of install with Windows

[mdede439]

I am stuck on step 7 where it says to run this command "west packages pip --install". I keep getting the error message -- west: unknown command "packages". I am installing the environment under Windows 10 and running the command from a regular user command prompt, not opened as administrator nor PowerShell. Am I doing something wrong?

Full message below:
(.venv) C:\NCS-Project>west packages pip --install
usage: west [-h] [-z ZEPHYR_BASE] [-v] [-q] [-V] ...
west: unknown command "packages"; workspace C:\NCS-Project does not define this extension command -- try "west help" and "west -vv status"
